Method Detail

isTransformable

public boolean isTransformable(Object from,
                               Class<?> toClass,
                               PropertyInfo propertyInfo)

Description copied from interface: CustomBeanTransformerSpi

Returns true if the given object is to be transformed by this transformer; false otherwise.

from - source object

toClass - target class

propertyInfo - If null, it means the in object is a root level object. Otherwise, propertyInfo contains information about the input object as a java bean property value to be transformed.

transform

public <T> T transform(Object in,

Description copied from interface: Transformable

Returns an object transformed from the input object with the given target class.

Specified by:

transform in interface Transformable

Parameters:

in - the input object to be transformed. If propertyInfo is non-null, the input object is a JavaBean property value.
