ForConstantValue
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.
-
ForConstantValue
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.
-
ForConstantValue
private ForConstantValue(Assigner assigner, Assigner.Typing typing, StackManipulation valueLoadInstruction, TypeDescription loadedType) Creates a new constant pool fixed value implementation.- 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.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 Details
-
withAssigner
Defines an explicit assigner to this fixed value implementation.- Specified by:
withAssigner
in interfaceFixedValue.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
Prepares a given instrumented type.- Specified by:
prepare
in interfaceInstrumentedType.Prepareable
- Parameters:
instrumentedType
- The instrumented type in its current form.- Returns:
- The prepared instrumented type.
-
appender
Creates a byte code appender that determines the implementation of the instrumented type's methods.- Specified by:
appender
in interfaceImplementation
- 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(org.objectweb.asm.MethodVisitor methodVisitor, Implementation.Context implementationContext, MethodDescription instrumentedMethod) Applies this byte code appender to a type creation process.- Specified by:
apply
in interfaceByteCodeAppender
- 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.
