Interface FieldTransform
- All Superinterfaces:
- ClassFileTransform<FieldTransform, FieldElement, FieldBuilder>
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface
public non-sealed interface FieldTransform
extends ClassFileTransform<FieldTransform, FieldElement, FieldBuilder>
A transformation on streams of 
FieldElement.
 
 Refer to ClassFileTransform for general guidance and caution around
 the use of transforms for structures in the class file format.
 
 A field transform can be lifted to a class transform via ClassTransform.transformingFields(FieldTransform), transforming only
 the FieldModel among the class members and passing all other elements
 to the builders.

endHandlerCreates a field transform that passes each element through to the builder, and calls the specified function when transformation is complete.- Parameters:
- finisher- the function to call when transformation is complete
- Returns:
- the field transform
 
- 
droppingCreates a field transform that passes each element through to the builder, except for those that the suppliedPredicateis true for.- Parameters:
- filter- the predicate that determines which elements to drop
- Returns:
- the field transform

andThenDescription copied from interface:ClassFileTransformChain this transform with another; elements presented to the builder of this transform will become the input to the next transform.This method is implemented by the Class-File API. Users usually don't have sufficient access to Class-File API functionalities to override this method correctly for generic downstream transforms. - Specified by:
- andThenin interface- ClassFileTransform<FieldTransform, FieldElement, FieldBuilder>
- Implementation Requirements:
- The default implementation returns this field transform chained with another field transform from the argument. Chaining of two transforms requires to involve a chained builder serving as a target builder for this transform and also as a source of elements for the downstream transform.
- Parameters:
- t- the downstream transform
- Returns:
- the chained transform
