Methods
  NameDescription
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodFindFunctionMapping(MemberInfo)
Finds the function mapping associated with the property specified.
Public methodFindFunctionMapping(MethodInfo)
Finds the function mapping associated with the method/function specified.
Protected methodFindFunctionMapping(String, Type, Int32)
Finds the function mapping associated with the method/function specified.
