public class BooleanUtils extends Object
Utilities for translating boxed Booleans to/from primitive bytes.

  • Field Details

    • NULL_BOOLEAN_AS_BYTE

      public static final byte NULL_BOOLEAN_AS_BYTE
      The byte encoding of null booleans. Do not use to compare values, use isNull(byte) instead.
      See Also:

    • TRUE_BOOLEAN_AS_BYTE

      public static final byte TRUE_BOOLEAN_AS_BYTE
      The byte encoding of true booleans. Do not use to compare values, use byteAsBoolean(byte) instead.
      See Also:

    • FALSE_BOOLEAN_AS_BYTE

      public static final byte FALSE_BOOLEAN_AS_BYTE
      The byte encoding of false booleans. This is the only safe value to use when comparing byte representations.
      See Also:

    • NULL_BOOLEAN_AS_BYTE_BOXED

      public static final Byte NULL_BOOLEAN_AS_BYTE_BOXED
      The byte encoding of the null boolean, as a boxed Byte.

  • Method Details

    • byteAsBoolean

      public static Boolean byteAsBoolean(byte byteValue)
      Convert byteValue to a Boolean.
      Parameters:
      byteValue - the byte to convert to a boxed boolean
      Returns:
      the boxed boolean represented by byteValue

    • isNull

      public static boolean isNull(byte byteValue)
      Check if a byte represents a null boolean.
      Parameters:
      byteValue - the byte to check if it represents a null boolean
      Returns:
      true if byteValue represents a null boolean

    • booleanAsByte

      public static byte booleanAsByte(Boolean booleanValue)
      Convert booleanValue to a byte.
      Parameters:
      booleanValue - the boxed boolean value to convert to a byte
      Returns:
      booleanValue represented as a byte

    • booleanAsByte

      public static byte booleanAsByte(boolean booleanValue)
      Convert booleanValue to a byte.
      Parameters:
      booleanValue - the unboxed boolean value to convert to a byte
      Returns:
      booleanValue represented as a byte

    • booleanAsByteArray

      public static byte[] booleanAsByteArray(boolean[] booleanArray)
      Convert an array of booleanValues to an array of bytes.
      Parameters:
      booleanArray - the primitive boolean array to convert to a byte
      Returns:
      booleanArray represented as a byte array

    • booleanAsByteArray

      public static byte[] booleanAsByteArray(Boolean[] booleanArray)
      Convert an array of booleanValues to an array of bytes.
      Parameters:
      booleanArray - the boxed boolean array to convert to a byte
      Returns:
      booleanArray represented as a byte array
