Constructor Details

Appender

protected Appender(TypeDescription instrumentedType,
 StackManipulation baseline,
 List<FieldDescription.InDefinedShape> fieldDescriptions,
 ElementMatcher<? super FieldDescription.InDefinedShape> nonNullable,
 ElementMatcher<? super FieldDescription.InDefinedShape> identity)

Creates a new appender.

Parameters:

instrumentedType - The instrumented type.

baseline - The baseline stack manipulation.

fieldDescriptions - A list of fields to use for the comparison.

nonNullable - A matcher to determine fields of a reference type that cannot be null.

identity - A matcher to determine that a field should be considered by its identity.

Method Details

apply

public ByteCodeAppender.Size apply(org.objectweb.asm.MethodVisitor methodVisitor,
 Implementation.Context implementationContext,
 MethodDescription instrumentedMethod)

Applies this byte code appender to a type creation process.

Specified by:

apply in interface ByteCodeAppender

Parameters:

methodVisitor - The method visitor to which the byte code appender writes its code to.

implementationContext - The implementation context of the current type creation process.

instrumentedMethod - The method that is the target of the instrumentation.

Returns:

The required size for the applied byte code to run.
