Constructor Detail

ForPoolValue

protected ForPoolValue(StackManipulation valueLoadInstruction,
                       Class<?> loadedType)

Creates a new constant pool fixed value implementation.

Parameters:

valueLoadInstruction - The instruction that is responsible for loading the constant pool value onto the operand stack.

loadedType - A type description representing the loaded type.

ForPoolValue

protected ForPoolValue(StackManipulation valueLoadInstruction,
                       TypeDescription loadedType)

Creates a new constant pool fixed value implementation.

Parameters:

valueLoadInstruction - The instruction that is responsible for loading the constant pool value onto the operand stack.

loadedType - A type description representing the loaded type.

Method Detail

withAssigner

public Implementation withAssigner(Assigner assigner,
                                   Assigner.Typing typing)

Defines an explicit assigner to this fixed value implementation.

Specified by:

withAssigner in interface FixedValue.AssignerConfigurable

Parameters:

assigner - The assigner to use for assigning the fixed value to the return type of the instrumented value.

typing - Indicates if dynamic type castings should be attempted for incompatible assignments.

Returns:

A fixed value implementation that makes use of the given assigner.

prepare

public InstrumentedType prepare(InstrumentedType instrumentedType)

Prepares a given instrumented type.

Specified by:

prepare in interface InstrumentedType.Prepareable

Parameters:

instrumentedType - The instrumented type in its current form.

Returns:

The prepared instrumented type.

appender

public ByteCodeAppender appender(Implementation.Target implementationTarget)

Creates a byte code appender that determines the implementation of the instrumented type's methods.

Specified by:

appender in interface Implementation

Parameters:

implementationTarget - The target of the current implementation.

Returns:

A byte code appender for implementing methods delegated to this implementation. This byte code appender is also responsible for handling methods that were added by this implementation on the call to InstrumentedType.Prepareable.prepare(InstrumentedType).

apply

public ByteCodeAppender.Size apply(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.
