java.lang.Object
  net.sourceforge.hiveutils.util.DefaultMethodMappingBuilder

All Implemented Interfaces:

MethodMappingBuilder

public class DefaultMethodMappingBuilder
extends java.lang.Object
implements MethodMappingBuilder

Default implementation to generate a mapping between public methods of a source class (or interface) into equivalent methods (same name, same arguments, compatible returned type, but possibly different thrown exceptions).

Method Detail

buildMapping

public java.util.Map<java.lang.reflect.Method,java.lang.reflect.Method> buildMapping(java.lang.Class source,
                                                                                     java.lang.Class target,
                                                                                     MethodMappingErrorHandler handler)

The method analyses all public methods of source class. For each method:

• search a public method with the name and arguments list in target
• check the returned type of the target method is assignable to the the returned type of the source method

If a source method has no target method with matches for name and arguments, then a warning is generated and that method will not appear in the returned Map.

Specified by:

buildMapping in interface MethodMappingBuilder

Parameters:

source - class (or interface) which methods need to be mapped to target

target - class (or interface) to which source methods need to be mapped

handler - the instance that will be called back when errors occur

Returns:

a Map of source Methods to equivalent target Methods
