Version 1 Current »


 
Returns the value of the one or more specified attributes of an application instance. The instance is specified by its numeric instanceID that uniquely identifies it in the remote EDMdatabase. The attributes are identified by their attributeIds.
Related function: edmiRemoteGetAttrsBN
Header:
#include "sdai.h"
Prototype:
EdmiError edmiRemoteGetAttrs(SdaiServerContext serverContextId,
                              SdaiInstance      instance, 
                              SdaiVersion       version, 
                              SdaiInteger       numberAttr, 
                              SdaiInvocationId  *edmiInvocationId, 
                             /* [SdaiAttr attributeId, SdaiPrimitiveType valueType, void *value] */ 
                               ...); 
 
Arguments:

serverContextId

Context identification, from edmiDefineServerContext

instance

A numeric instanceID that uniquely identifies the instance of interrest in the remote _EDMdatabase{_}.

version

The version of the edmModel to apply this function call on. The <version> parameter is a numeric sequence number counting from one by increments of one for each new model version that is created. A zero model version number means the current version.

numberAttr

The number of attributes for which to to assign values.

edmiInvocationId

Currently not used.

value

For each attribute value to read the following three arguments must be specified:

  1. <attributeID> : The numeric attributeId that uniquely identifies the attribute definition instance in the remote EDMdatabase.
  2. <valueType> : The primitive type of the attribute. This type must be the same as the actual data type of the attribute value or any compatible data type. The primitive type sdaiSELECT can be used to get all data types. The primitive type sdaiADB can be used to get all data types except typed values. The primitive type sdaiINTEGER is compatible with sdaiREAL, and sdaiBOOLEAN is compatible with sdaiLOGICAL, hence conversion between these compatible data types will be performed automatically when required.
  3. <value> : The variable that will hold receive the data value from the actual attribute.

Returns:
A completion code of datatype EdmiError is the returned function value. The completion code has the following values:
Completion code = 0 : Operation successfully performed.
Completion code != 0: Error in operation. Completion code is an _EDMinterface_ error code. Use edmiGetErrorText to get the error text corresponding to the error code.
Example:
#define S_NATTR 3
int i, j;
EdmiError rstat;
SdaiServerContext myContext;
SdaiInteger index, nHits;
SdaiAttr attrIds[S_NATTR];
SdaiQueryResult qexRes;
SdaiString attrVals[S_NATTR];
 
/* Create Server Context */
rstat = edmiDefineServerContext("MyContext",
"Johnny", "Supervisor", "cf37ftr", 
"TCP", "9090", "MyServerHost", 
NULL, NULL, NULL, NULL, NULL, &myContext); 
 
/* Get attribute ids of the Person entity */
rstat = edmiRemoteGetAttrDefinitionBN(myContext, "MySocialRelations",
"Person", "FIRST_NAME", &attrIds[0], NULL); 
rstat = edmiRemoteGetAttrDefinitionBN(myContext, "MySocialRelations",
"Person", "LAST_NAME", &attrIds[1], NULL); 
rstat = edmiRemoteGetAttrDefinitionBN(myContext, "MySocialRelations",
"Person", "PHONE_NO", &attrIds[2], NULL); 
 
/* Select all person instances */
rstat = edmiRemoteSelectInstances(myContext, "MyRepository",
"MySocialRelations", "Person", 
NULL, ONLY_INSTANCE_IDS, NULL, NULL, NULL, 
&index, &nHits, &qexRes, NULL, NULL, NULL, NULL); 
 
/* Get their names and phone numbers */
for (i=0;i<nHits;i++) {
rstat = edmiRemoteGetAttrs(myContext,
qexRes->instanceIds[i], 0, S_NATTR, NULL,  
attrIds[0], sdaiSTRING, &attrVals[0], 
attrIds[1], sdaiSTRING, &attrVals[1], 
attrIds[2], sdaiSTRING, &attrVals[2]); 
 
printf("\n%s %s, Phone No. %s",  
attrVals[0], attrVals[1], attrVals[2]); 
 
for (j=0;j<=S_NATTR;j++) { 
edmiFree(attrVals[j]); 

}
edmiFreeQueryResult(qexRes);
