Method Summary

java.lang.Object	createInstance(java.lang.Class clazz) Creates an instance of the type clazz.
java.lang.String	getMethodName(java.lang.Class clazz, java.lang.String attribute, boolean set) Returns the get/set method name for an attribute read by the parser
void	init() Restore initial state
java.lang.Class	resolveInterface(java.lang.Object object) Determines the interfaces this object was created upon.
void	setAttribute(java.lang.Object target, java.lang.String attribute, java.lang.Object value) Sets the attribute on an instance returned via createInstance(Class) target and attribute are guaranteed to be not null.

Method Detail

createInstance

java.lang.Object createInstance(java.lang.Class clazz)

Creates an instance of the type clazz.

clazz is never null

Parameters:

clazz -

Returns:

An instance of the type clazz.

setAttribute

void setAttribute(java.lang.Object target,
                  java.lang.String attribute,
                  java.lang.Object value)

Sets the attribute on an instance returned via createInstance(Class)

target and attribute are guaranteed to be not null.

value is guaranteed to be not null if called by the parser

Parameters:

target - Object to set the attribute to

attribute - Attribute name

value - value to set

init

void init()

Restore initial state

resolveInterface

java.lang.Class resolveInterface(java.lang.Object object)

Determines the interfaces this object was created upon.

Parameters:

object - Object created by createInstance(Class) of this object

Returns:

Target The interfaces this object was created upon.

getMethodName

java.lang.String getMethodName(java.lang.Class clazz,
                               java.lang.String attribute,
                               boolean set)

Returns the get/set method name for an attribute read by the parser

Parameters:

clazz -

attribute -

set - true if set method is requested, false if get

Returns:

Null if attribute can not be handled or strategy does not support the operation, name of method otherwise
