Syntax

return = objectName._getMethod( methodName, metadata );

return = objectName._getMethod( methodID, metadata2 );

return = objectName._getMethod( methodName, metadata3, instance );

return = objectName._getMethod( methodID, metadata4, instances );

Argument Type Use Description

return Numeric Return returns a value indicating whether the method was successfully retrieved: 0 if successful, 1 if not successful

methodName Character Input specifies the name of the method you want to retrieve

metadata Numeric Update specifies the identifier of a list that when returned contains method metadata. If the method is overloaded, the list will contain a sublist for each signature.

methodID Numeric Input specifies the unique id of the method you want to retrieve. Useful when a method is overloaded to uniquely identify the method.

metadata2 List Update specifies the identifier of a list that when returned contains method metadata

metadata3 List Update specifies the identifier of a list that when returned is filled with the method metadata

instance Character Input specifies whether methods are returned for instances of the class. This option is only valid for class instances.

metadata4 List Update specifies the identifier of a list that when returned is filled with method metadata

instances Character Input specifies whether the method is returned for instances of the class. This option is valid for class instances only.

methodID	Numeric	Input	specifies the unique id of the method you want to retrieve. Useful when a method is overloaded to uniquely identify the method.
metadata2	List	Update	specifies the identifier of a list that when returned contains method metadata
metadata3	List	Update	specifies the identifier of a list that when returned is filled with the method metadata
instance	Character	Input	specifies whether methods are returned for instances of the class. This option is only valid for class instances.
metadata4	List	Update	specifies the identifier of a list that when returned is filled with method metadata
instances	Character	Input	specifies whether the method is returned for instances of the class. This option is valid for class instances only.

Details

Consider the following information when you use _getMethod:

Use the _getMethod signature that passes the instance argument only with class IDs; use the other _getMethod signatures with either class ID or instance.
To retrieve the metadata for a specific signature, use the form _getMethod(methodID). If you use the method name as the argument, you retrieve the first signature in the list.
_getMethod does not return a method in an ancestor class that is out of scope (that is, defined as private or protected) for the calling object or class. You can use _getIMethodList if you need to return all methods regardless of scope.
