Enum ConversionInstruction.ConversionType

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      D2F
      Narrows a double to a float, rounding to nearest and overflowing to infinity.
      D2I
      Converts a double to an int, truncating toward zero and clamping to the int range; NaN becomes zero.
      D2L
      Converts a double to a long, truncating toward zero and clamping to the long range; NaN becomes zero.
      F2D
      Widens a float to a double without loss of value.
      F2I
      Converts a float to an int, truncating toward zero and clamping to the int range; NaN becomes zero.
      F2L
      Converts a float to a long, truncating toward zero and clamping to the long range; NaN becomes zero.
      I2D
      Widens an int to a double without loss of value.
      I2F
      Converts an int to a float, rounding to nearest when the magnitude exceeds 24 bits of precision.
      L2D
      Converts a long to a double, rounding to nearest when the magnitude exceeds 53 bits of precision.
      L2F
      Converts a long to a float, rounding to nearest when the magnitude exceeds 24 bits of precision.
      L2I
      Narrows a long to an int by keeping only the low 32 bits.

    • Method Detail

      • values

        public static ConversionInstruction.ConversionType[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (ConversionInstruction.ConversionType c : ConversionInstruction.ConversionType.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static ConversionInstruction.ConversionType 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

      • getOpcode

        public int getOpcode()
        Returns:
        the opcode

      • getMnemonic

        public String getMnemonic()
        Returns:
        the mnemonic

      • fromOpcode

        public static ConversionInstruction.ConversionType fromOpcode​(int opcode)
        Looks up the conversion type for a JVM opcode.
        Parameters:
        opcode - the JVM opcode
        Returns:
        the matching type, or null if the opcode is not a conversion opcode
