Original Class: SOMClass

Syntax

boolean somSupportsMethod (SOMClass receiver, somId methodId)

Parameters

receiver (SOMClass): A pointer to the class object to be tested.

methodId (somId): An ID that represents the name of the method.

Return Code

rc (boolean): Returns 1 (true) if instances of the specified class support the specified method, and 0 (false) otherwise.

Remarks

The somSupportsMethod method determines if instances of the specified class respond to the specified (static or dynamic) method.

Example Code

/* ------------------------------------------------
   Note:  animal supports a setSound method;
          animal does not support a doTrick method.
   ------------------------------------------------ */
#include <animal.h>
main()
{
  SOMClass animalClass;
  char *methodName1 = "setSound";
  char *methodName2 = "doTrick";
  animalClass =
      AnimalNewClass(Animal_MajorVersion, Animal_MinorVersion);
  if (_somSupportsMethod(animalClass,
                         somIdFromString(methodName1)))
      somPrintf("Animals respond to %s\n", methodName1);
  if (_somSupportsMethod(animalClass,
                          somIdFromString(methodName2)))
      somPrintf("Animals respond to %s\n", methodName2);
}
