Method Detail

setEntity

public void setEntity(E entity,
                      String fieldName,
                      V value)
               throws Exception

Parameters:

entity - as The entity to process or initialize for the field-value we want to set in it.

fieldName - as String, to set the value in the Entity for this field

value - as the value to set once processing is done.

Throws:

Exception

getProcessor

public EntityFieldSetter<E,V> getProcessor()

Takes in the main Entity type of the transformation process and initializes whatever fields are require and then sets it

setProcessor

public void setProcessor(EntityFieldSetter<E,V> processor)

Takes in the main Entity type of the transformation process and initializes whatever fields are require and then sets it

getPredicate

public Predicate<V> getPredicate()

If the Predicate.test(Object) is true then #process should be called
If null will only process if value passed to this is not null. To override this one may pass a custom Predicate.

setPredicate

public void setPredicate(Predicate<V> predicate)

If the Predicate.test(Object) is true then #process should be called
If null will only process if value passed to this is not null. To override this one may pass a custom Predicate.
