Enum FloatConstant

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

  • Enum Constant Details

    • ZERO

      public static final FloatConstant ZERO
      A float constant of value 0.0f.

    • ONE

      public static final FloatConstant ONE
      A float constant of value 1.0f.

    • TWO

      public static final FloatConstant TWO
      A float constant of value 2.0f.

  • Field Details

    • SIZE

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

    • opcode

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

  • Constructor Details

    • FloatConstant

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

  • Method Details

    • values

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

    • valueOf

      public static FloatConstant valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name
      NullPointerException - if the argument is null

    • forValue

      public static StackManipulation forValue(float value)
      Creates a stack manipulation for loading a float 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 float value to load onto the stack.
      Returns:
      A stack manipulation for loading the given float 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.
