Constructor Details

MethodCodeTransform

public MethodCodeTransform(CodeTransform xform)

Creates an instance of a MethodCodeTransform record class.

Parameters:

xform - the value for the xform record component

Method Details

resolve

public 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>

Specified by:

resolve in interface MethodTransform

Parameters:

builder - the builder to bind to

Returns:

the bound result

andThen

public MethodTransform andThen(MethodTransform next)

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>

Specified by:

andThen in interface MethodTransform

Parameters:

next - the downstream transform

Returns:

the chained transform

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

xform

public CodeTransform xform()

Returns the value of the xform record component.

Returns:

the value of the xform record component

accept

default void accept(MethodBuilder builder,
 MethodElement element)

Description copied from interface: ClassfileTransform

Transform an element by taking the appropriate actions on the builder. Used when transforming a classfile entity (class, method, field, method body.) If no transformation is desired, the element can be presented to ClassfileBuilder.with(ClassfileElement). If the element is to be dropped, no action is required.

Specified by:

accept in interface ClassfileTransform<MethodTransform,MethodElement,MethodBuilder>

Parameters:

builder - the builder for the new entity

element - the element

atEnd

default void atEnd(MethodBuilder builder)

Description copied from interface: ClassfileTransform

Take any final action during transformation of a classfile entity. Called after all elements of the class are presented to ClassfileTransform.accept(ClassfileBuilder, ClassfileElement).

Specified by:

atEnd in interface ClassfileTransform<MethodTransform,MethodElement,MethodBuilder>

Parameters:

builder - the builder for the new entity

atStart

default void atStart(MethodBuilder builder)

Description copied from interface: ClassfileTransform

Take any preliminary action during transformation of a classfile entity. Called before any elements of the class are presented to ClassfileTransform.accept(ClassfileBuilder, ClassfileElement).

Specified by:

atStart in interface ClassfileTransform<MethodTransform,MethodElement,MethodBuilder>

Parameters:

builder - the builder for the new entity
