| |
| | |
| This document describes the C++ class definitions for code that implements | |
| the semantics for records created from Database Definitions. The definitions
| |
| are intended for code that:
| |
| * includes header files generated from dbd definitions. Header files are generated from the following dbd definitions:
| |
| ** <tt>record</tt>
| |
| ** <tt>struct</tt>
| |
| ** <tt>menu</tt>
| |
| * does not include the header files.
| |
| | |
| The following headers files are described:
| |
| * <tt>epicsTypes.h</tt> - A set of primitive types that are part of <tt>base/src/libCom</tt>
| |
| * <tt>dbdTypes.h</tt> - Type definitions for non-primitive <field> definitions in <struct> or <record> DBD definitions.
| |
| * <tt>dbdStatements.h</tt> - Type definitions for DBD statements.
| |
| * <tt>dbdInterfaces.h</tt> - Type definitions for interfaces related to DBD definitions.

| |
| === <tt>epicsTypes.h</tt> ===
| |
| <tt>epicsTypes.h</tt> defines a set of primitive tupes. It is used because the <tt>C99<tt> standard does not define the exact number of bits for the primitive data types. It only defines the minimum number of bits.
| |
| | |
| In addition two extra types are defined:
| |
| * epicsUnknownT - Unknown
| |
| * epicsOctetT - An 8 bit byte.
| |
| | |
| <tt>epicsTypes.h</tt> contains the following:
| |
| | |
| enum epicsType {
| |
| epicsUnknownT,
| |
| epicsBooleanT,
| |
| epicsOctetT,
| |
| epicsInt16T,
| |
| epicsUInt16T,
| |
| epicsInt32T,
| |
| epicsUInt32T,
| |
| epicsInt64T,
| |
| epicsUInt64T,
| |
| epicsFloat32T,
| |
| epicsFloat64T,
| |
| };
| |
| | |
| /* some of the following may require OSD definitions*/
| |
| typedef bool epicsBoolean;
| |
| typedef char epicsOctet;
| |
| typedef short epicsInt16;
| |
| typedef unsigned short epicsUInt16;
| |
| typedef int epicsInt32;
| |
| typedef unsigned int epicsUInt32;
| |
| typedef long long epicsInt64;
| |
| typedef unsigned long long epicsUInt64;
| |
| typedef float epicsFloat32;
| |
| typedef double epicsFloat64;
| |
| | |
| === Discussion of epicsTypes ===
| |
| | |
| | |
| The types epicsBoolean, epicsOctet, epicsInt16, epicsUInt16, epicsInt32, epicsUInt32, epicsInt64, epicsUInt64, epicsFloat32, epicsFloat64 all map to a C or C++ primitive type. It may be necessary to provide operating system dependent definitions for some of the types. For example on some architectures a epicsInt64 may have to be defined as a <tt>long</tt> rather than a <tt>long long</tt>.
| |
| | |
| If a record is defined as:
| |
| record(xxx) extends iocRecord {
| |
| ...
| |
| field(fbool,bool)
| |
| field(foctet,octet)
| |
| ...
| |
| field(ffloat64,float64)
| |
| ...
| |
| }
| |
| Then the generated header file will be
| |
| class xxxRecord : iocRecord {
| |
| public:
| |
| epicsBoolean fbool;
| |
| epicsOctet foctet;
| |
| ...
| |
| epicsFloat64 ffloat64;
| |
| ...
| |
| };
| |
| | |
| <tt>epicsType epicsTypeUnknownT</tt> is reserved for unknown types and will normally be cause by some configuration error.

| === <tt>dbdTypes.h</tt> ===
| |
| File dbdTypes.h describes the non-primitive types used by V4 databases:
| |
| The following naming conventions are used:
| |
| ; Dbf
| |
| : any class starting with Dbf describes a struct or record field. For example DbfString describes a field(name,string).
| |
| ; *Dbd*
| |
| : A class name that has Dbd imbeded in it describes something directly related to a dbd statement. For example LinkDbdSupport describes a dbd link definition.
| |
| | |
| <tt>dbdTypes.h</tt> contains the following:
| |
| #include <epicsTypes.h>
| |
| enum dbdType {
| |

| | |
| === Discussion of dbdTypes ===
| |
| | |
| ==== Primitive Types ====
| |
| The types dbdBoolean, dbdOctet, dbdInt16, dbdUInt16, dbdInt32, dbdUInt32, dbdInt64, dbdUInt64, dbdFloat32, dbdFloat64 all map to an epicsType.
| |
| ==== DbfString ====
| |
| <tt>DbfString</tt> is described as:
| |
| class DbfString {
| |
| public:
| |
| dbdInt32 capacity; /*capacity in bytes*/
| |
| dbdOctet *pstorage;
| |
| };
| |
| If a record definition contains
| |
| field(sfield,string)
| |
| Then the generated header file contains
| |
| DbfString sfield;
| |
| | |
| <tt>pstorage</tt>will always be the address of a UTF-8 null terminated character string. The <tt>capacity</tt> is the the number of bytes referenced by <tt>pstorage</tt> NOT the number of characters.
| |
| | |
| A support library and rules must be created for managing DbfStrings.
| |
| | |
| ==== DbfStruct ====
| |
| | |
| <tt>DbfStruct></tt> is described as:
| |
| class DbfStruct{
| |
| public:
| |
| StructDbdDef *pstructDef;
| |
| StructDbd *pstruct; // address of storage
| |
| };
| |
| | |
| If a record definition contains
| |
| field(sstruct,struct(name))
| |
| Then the generated header file contains
| |
| DbfStruct sfield;
| |
| <tt>pstruct</tt> is the address of storage for the structure and <tt>pstructDef</tt> is the address of a description of the structure. StructDbdDef is described in <tt>dbdStatatements.h</tt>
| |
| | |
| Note that given a dbdStruct it is possible to locate both the address and description of the associated structure.
| |
| | |
| ==== DbfArray ====
| |
| | |
| Discussion needed. Note that multi-dimensional arrays must also be described.
| |
|
| |
| | |
| ==== DbfMenu ====
| |
| <tt>dbdMenu></tt> is described as:
| |
| class DbfMenu{
| |
| public:
| |
| dbdInt16 index;
| |
| MenuDbfDef *pmenuDef;
| |
| };
| |
| | |
| If a record definition contains
| |
| field(fmenu,menu(name))
| |
| Then the generated header file contains
| |
| DbfMenu fmenu;
| |
| The definition of dbdMenu provides the current menu index and also the menu definition.
| |
| | |
| ==== DbfEnum ====
| |
| <tt>DbfEnum></tt> is described as:
| |
| class DbfEnum{
| |
| public:
| |
| dbdInt16 index;
| |
| MenuDbdDef *pmenuDef; /* address of record instance menu */
| |
| };
| |
| | |
| If a record definition contains
| |
| field(fenum,enum)
| |
| Then the generated header file contains
| |
| DbfEnum fenum;
| |
| Note that the definition of DbfEnum looks identical to DbfMenu. The difference
| |
| is that DbfMenu has the address of a global MenuDbfDef but DbfEnum has the addrsss of a MenuDbfDef that belongs to the record instance.
| |
| ==== DbfLink ====
| |
| <tt>DbfLink</tt> is described as
| |
| class DbfLink{
| |
| public:
| |
| LinkDir dir;
| |
| LinkDbd *plinkDef;
| |
| DbfStruct dataStruct;
| |
| };
| |
| If a record definition contains
| |
| field(flink,link(in))
| |
| Then the generated header file contains
| |
| DbfLink flink;
| |
| The fields of DbfLink are initialized by locating a dbd <tt>link</tt> definition that matches the <tt>dir</tt> specified in the dbd <tt>field</tt> definition.
| |
| | |
| The fields of <tt>DbfLink</tt> are initialized as follows:
| |
| ; <tt>dir</tt>
| |
| : This is taken from either the <tt>field</tt> definition or from the <tt>LinkDbd</tt> definition and is the most restrictive. For example if one says inout and the other says in then <tt>dir</tt> will be in.
| |
| ; <tt>choiceName</tt>
| |
| : The record instance specifies this and it is used to locate the associated dbd <tt>link</tt> definition.
| |
| ; <tt>plinkDef</tt>
| |
| : This is the address of the <tt>LinkDbd</tt>.
| |
| ; <tt>dataStruct</tt>
| |
| : The describes the data structure specified in the dbd <tt>link</tt> definition. It contains data used by the link support.
| |
| | |
| Note that link support always implements interface <tt>LinkDbdSupport</tt>
| |
| ==== dbdDevice ====
| |
| | |
| A <tt>dbdDevice</tt> is similar to a <tt>dbdLink</tt> except that the interface implemented by the device support is also specified, i.e. instead of implementing interface <tt>LinkDbdSupport</tt>, the device support implements an interface that both record support and device support understand.

| | |
| === Discussion of dbdStatements ===
| |
| The classes in <tt>dbdStatements.h</tt> allow introspection of ioc records. They describe everything defined in DBD definitions.
| |
| ==== Struct ===
| |
| The Struct classes describe the fields in a dbd <tt>struct</tt> or <tt>record</tt> definition. The classes are : <tt>StructDbdDef</tt>, <tt>StructDbdField</tt>,and <tt>StructFieldAttribute</tt>
| |
| The fields of <tt>StructDbdDef</tt> are:
| |
| ; <tt>name</tt>
| |
| : The name of the struct.
| |
| ; <tt>plifetime</tt>
| |
| : The address of an implementation of interface <tt>StructDbdLifetime</tt>. The implementation is automatically generated from the dbd <tt>struct</tt> statement. See below for a description of the <tt>StructDbdLifetime</tt> methods.
| |
| ; <tt>nfields</tt>
| |
| : The number of fields, e.g. fields in the structure.
| |
| ; <tt>pfields</tt>
| |
| : pointer to an array of pointers to <tt>StructDbdField</tt>. Each StructDbdField contains the name and type of the fields.
| |
| | |
| The fields of <tt>StructDbdField</tt> are:
| |
| ; <tt>name</tt>
| |
| : The name of the field
| |
| ; <tt>type</tt>
| |
| : The dbfType for the field.
| |
| ; <tt>pattribute</tt>
| |
| : The address of a StructFieldAttribute for the field
| |
| | |
| The fields of <tt>StructFieldAttribute</tt> show the falue of the attributes for the field.
| |
| | |
| ==== Menu ===
| |
| | |
| A dbd <tt>menu</tt> is described by the classes: MenuDbdDef and MenuDbdChoice
| |
| | |
| The fields of MenuDbdDef are:
| |
| ; <tt>name</tt>
| |
| : The menu name.
| |
| ; <tt>nchoices</tt>
| |
| : The number of menu choices.
| |
| ; <tt>pchoice</tt>
| |
| : The address of an array of pointers to choices
| |
| | |
| The fields of MenuDbdChoice described a single choice:
| |
| ; <tt>choiceName</tt>
| |
| : The choice name, i.e. the C++ variable name that appears in the generated enum statement for the menu
| |
| ; <tt>menuName</tt>
| |
| : The menu choice that DCTs and the value returned when the menu choice strings are requested.
| |
| | |
| === Link and Device ===
| |
| | |
| Each dbd <tt>link</tt> definition has an associated class LinkDbd with fields:
| |
| ; <tt>dir</tt>
| |
| : The link direction
| |
| ; <tt>choiceName</tt>
| |
| : The name that to find a LinkDbd for a DbfLink instance.
| |
| ; <tt>dataStructName</tt>
| |
| : The class name of a DbfStruct for the Interface implementation
| |
| ; <tt>pinterface</tt>
| |
| : The address of the Interface implementation. The interface class is LinkDbdSupport
| |
| | |
| Each dbd <tt>device</tt> definition has an associated class DeviceDbd with fields:
| |
| ; <tt>dir</tt>
| |
| : The link direction
| |
| ; <tt>interfaceName</tt>
| |
| : The name of the interface class implemented by the device support
| |
| ; <tt>choiceName</tt>
| |
| : The name that to find a LinkDbd for a DbfLink instance.
| |
| ; <tt>dataStructName</tt>
| |
| : The class name of a DbfStruct for the Interface implementation
| |
| ; <tt>pinterface</tt>
| |
| : The address of the Interface implementation. The interface class is LinkDbdSupport

| === Discussion of dbdInterfaces ===
| |
| ==== <tt>StructDbdLifetime</tt> ====
| |
| Every dbd <tt>struct</tt> and <tt>record</tt> has an associated <tt>StructDbdLifetime</tt> interface implementation. A tool is provided that automatically generates the implementation form the dbd definition.
| |
| <tt>StructDbdLifetime</tt> is described as:
| |
| class StructDbdLifetime {
| |
| public:
| |
| virtual StructDbdPtr create() = 0;
| |
| virtual bool initialize(dbfString *errorMessage,
| |
| StructDbdPtr ptr) = 0;
