Enum Class DoubleConstant

java.lang.Object
java.lang.Enum<DoubleConstant>
net.bytebuddy.implementation.bytecode.constant.DoubleConstant
All Implemented Interfaces:
Serializable, Comparable<DoubleConstant>, Constable, StackManipulation
public enum DoubleConstant extends Enum<DoubleConstant> implements StackManipulation
This class is responsible for loading any double constant onto the operand stack.

  • Enum Constant Details

    • ZERO

      public static final DoubleConstant ZERO
      A double constant of value 0.0.

    • ONE

      public static final DoubleConstant ONE
      A double constant of value 1.0.

  • Field Details

    • SIZE

      private static final StackManipulation.Size SIZE
      The size impact of loading a double constant onto the operand stack.

    • opcode

      private final int opcode
      The shortcut opcode for loading a double constant.

  • Constructor Details

    • DoubleConstant

      private DoubleConstant(int opcode)
      Creates a new shortcut operation for loading a common double onto the operand stack.
      Parameters:
      opcode - The shortcut opcode for loading a double constant.

  • Method Details

    • values

      public static DoubleConstant[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static DoubleConstant valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null

    • forValue

      public static StackManipulation forValue(double value)
      Creates a stack manipulation for loading a double value onto the operand stack.

       

      This is achieved either by invoking a specific opcode, if any, or by creating a constant pool entry.
      Parameters:
      value - The double value to load onto the stack.
      Returns:
      A stack manipulation for loading the given double value.

    • isValid

      public boolean isValid()
      Determines if this stack manipulation is valid.
      Specified by:
      isValid in interface StackManipulation
      Returns:
      If false, this manipulation cannot be applied and should throw an exception.

    • apply

      public StackManipulation.Size apply(org.objectweb.asm.MethodVisitor methodVisitor, Implementation.Context implementationContext)
      Applies the stack manipulation that is described by this instance.
      Specified by:
      apply in interface StackManipulation
      Parameters:
      methodVisitor - The method visitor used to write the method implementation to.
      implementationContext - The context of the current implementation.
      Returns:
      The changes to the size of the operand stack that are implied by this stack manipulation.
