Field Details

ACCEPT_ALL

static final MethodTransform ACCEPT_ALL

A method transform that sends all elements to the builder.

Method Details

ofStateful

static MethodTransform ofStateful(Supplier<MethodTransform> supplier)

Create a stateful method transform from a Supplier. The supplier will be invoked for each transformation.

Parameters:

supplier - a Supplier that produces a fresh transform object for each traversal

Returns:

the stateful method transform

endHandler

static MethodTransform endHandler(Consumer<MethodBuilder> finisher)

Create a method 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 method transform

dropping

static MethodTransform dropping(Predicate<MethodElement> filter)

Create a method transform that passes each element through to the builder, except for those that the supplied Predicate is true for.

Parameters:

filter - the predicate that determines which elements to drop

Returns:

the method transform

transformingCode

static MethodTransform transformingCode(CodeTransform xform)

Create a method transform that transforms CodeModel elements with the supplied code transform.

Parameters:

xform - the method transform

Returns:

the class transform

resolve

default ClassfileTransform.ResolvedTransform<MethodElement> resolve(MethodBuilder builder)

Description copied from interface: ClassfileTransform

Bind a transform to a builder. If the transform is chained, intermediate builders are created for each chain link. If the transform is stateful (see, e.g., ClassTransform.ofStateful(Supplier)), the supplier is invoked to get a fresh transform object.

This method is a low-level method that should rarely be used by user code; most of the time, user code should prefer ClassfileBuilder.transform(CompoundElement, ClassfileTransform), which resolves the transform and executes it on the current builder.

Specified by:

resolve in interface ClassfileTransform<MethodTransform,MethodElement,MethodBuilder>

Parameters:

builder - the builder to bind to

Returns:

the bound result

andThen

default MethodTransform andThen(MethodTransform t)

Description copied from interface: ClassfileTransform

Chain this transform with another; elements presented to the builder of this transform will become the input to the next transform.

Specified by:

andThen in interface ClassfileTransform<MethodTransform,MethodElement,MethodBuilder>

Parameters:

t - the downstream transform

Returns:

the chained transform
