Description copied from interface: ObjectTransform

Our one method; this transforms one object into another. Transformation must be nondestructive, but may produce a derived product that is still affected by changes to the original, so beware.

Specified by:

transform in interface ObjectTransform

getElseTransform

public ObjectTransform getElseTransform()

Optional transform to run if ifCondition evaluates to false. By default passes the object through unchanged.

setElseTransform

public void setElseTransform(ObjectTransform newElseTransform)

Transform run if ifCondition evaluates to false.

getIfCondition

public UnaryPredicate getIfCondition()

Condition which, if it evaluates to true, runs the thenTransform, otherwise runs the elseTransform if it exists.

setIfCondition

public void setIfCondition(UnaryPredicate newIfCondition)

Condition which, if it evaluates to true, runs the thenTransform, otherwise runs the elseTransform if it exists.

getThenTransform

public ObjectTransform getThenTransform()

Transform run if ifCondition evaluates to true.

setThenTransform

public void setThenTransform(ObjectTransform newThenTransform)

Transform run if ifCondition evaluates to true.
