EdmiError edmiRemoteIsInstanceOfBN(SdaiServerContext serverContextId,
SdaiInstance instanceId,
SdaiString entityName,
SdaiBoolean *isInstanceOf,
SdaiInvocationId *edmiInvocationId);
Determines whether an instance is an instance of exactly the specified instance type.
Arguments
| Type | Name | Comment |
| SdaiServerContext | serverContextId | Context identification, from edmiDefineServerContext |
SdaiInstance | instanceId | A numeric instanceID that uniquely identifies the instance of interest in the remote database |
| SdaiString | entityName | The name of the entity. The entity must be defined by the underlying Express Schema of the edmModel that contains the instance given by the <instanceId> argument. Entity names are case insensitive. |
| SdaiBoolean | isInstanceOf | A variable that will receive TRUE if the instance given in argument <instanceId> is of the instance type given in the argument <entityId>. Otherwise, FALSE will be returned. |
| SdaiInvocationId | edmiInvocationId | Currently not used. |
