Method Detail

transform

public abstract Component transform(Component cc)

Transforms one Component object to another.

Parameters:

cc - the Component object to transform.

Returns:

the transformed Component object.

transform

public Component transform(java.lang.Object key,
                           Component cc)

Transforms one Component object to another. By default, this delegates to transform(cc);

Parameters:

key - the component key.

cc - the component.

Returns:

the transformed Component object.

seq

public final ComponentTransformer seq(ComponentTransformer ct)

Create a new ComponentTransformer by sequencing this transformer and another transformer. i.e., t1.seq(t2).transform(cc) is equivalent to t2.transform(t1.transform(cc)).

Parameters:

ct - the ComponentTransformer object to sequence with.

Returns:

the new ComponentTransformer object.
