getInstanceClass

public Class<?> getInstanceClass()

Gets the class of instances created by this class definition.

If the class loading fails, an error message is logged and a null value is returned.

Before triggering the class loading, makes sure that the class library is known to the context class loader.

Specified by:

Overrides:

getInstanceClass in class ClassDefEntity

Returns:

The requested class (null on failure).

getMember
