  • Constructor Details

    • ConstantDynamic

      public ConstantDynamic(String name, String descriptor, Handle bootstrapMethod, Object... bootstrapMethodArguments)
      Constructs a new ConstantDynamic.
      Parameters:
      name - the constant name (can be arbitrary).
      descriptor - the constant type (must be a field descriptor).
      bootstrapMethod - the bootstrap method to use to compute the constant value at runtime.
      bootstrapMethodArguments - the arguments to pass to the bootstrap method, in order to compute the constant value at runtime.
