  net.sf.gilead.core.beanlib.transformer.UnionCustomBeanTransformer

public class UnionCustomBeanTransformer
extends java.lang.Object

The UnionCustomBeanTransformer hold an array of CustomBeanTransformerSpi, checks if a given instance of a source class if transformable into a destination class iterating over the array of CustomBeanTransformerSpi finding the first appropriate one. Transforms the given instance of the source class into and instance of a destination class iterating over the array of CustomBeanTransformerSpi finding the first appropriate one.

Method Detail

isTransformable

public <T> boolean isTransformable(java.lang.Object from,
                                   java.lang.Class<T> toClass,
                                   PropertyInfo propertyInfo)

Iterate over the given array of CustomBeanTransformerSpi, checking if there is a valid transformer to transform the 'from' object, to the target 'toClass'

Parameters:

from - the source object instance

toClass - the destination class to transform the 'from' object in

Returns:

true if a custom bean transformer was found, false if not

transform

public <T> T transform(java.lang.Object in,
                       java.lang.Class<T> toClass,
                       PropertyInfo propertyInfo)

Transforms 'in' object into an instance of class 'toClass', using the first valid transformer in the _customTransformers array. Returns null if no valid customTransmer is available.

Parameters:

in - the source object to be transformed

toClass - the destination class which the instance will be returned

propertyInfo - the property which will be passed on the to the valid CustomBeanTransformerSpi registered

Returns:

instance of the 'toClass' as a result of a transformation of the 'in' object
