EdmiError edmiRemoteIsKindOf(SdaiServerContext serverContextId,
                               SdaiInstance      instanceId,

Determines whether an instance is of a specified instance type or of any subtype of this instance type. The instance type is identified by its unique entityId. This operation returns sdaiTRUE if the specified instance is of the specified instance type or a subtype of this instance type, else sdaiFALSE is returned.

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 EDMdatabase
SdaiEntity	entityId	A numeric entityID that uniquely identifies an entity definition instance in a dictionary model in the remote EDMdatabase
SdaiBoolean	isKindOf	A variable that will receive sdaiTRUE if the instanceId given in argument <instanceId> is of an instance type equal to that given in argument <entityId> or to any of its subtypes. If there is no such type relation, sdaiFALSE will be returned.
SdaiInvocationId	edmiInvocationId	Currently not used.

Return Value
