Enclosing class:
FixedValue

@Enhance protected static class FixedValue.ForPoolValue extends FixedValue implements FixedValue.AssignerConfigurable, ByteCodeAppender
A fixed value implementation that represents its fixed value as a value that is written to the instrumented class's constant pool.
  • Field Details

    • valueLoadInstruction

      private final StackManipulation valueLoadInstruction
      The stack manipulation which is responsible for loading the fixed value onto the operand stack.
    • loadedType

      private final TypeDescription loadedType
      The type of the fixed value.
  • Constructor Details

    • 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.

    • ForPoolValue

      protected ForPoolValue(StackManipulation valueLoadInstruction, TypeDescription loadedType)
      Creates a new constant pool fixed value implementation.
      Parameters:

    • ForPoolValue

      private ForPoolValue(Assigner assigner, Assigner.Typing typing, 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.
      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.
  • Method Details

    • 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(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.
