  • malformedForLength

    public static CoderResult malformedForLength(int length)
                                          throws IllegalArgumentException

    Gets a CoderResult object indicating a malformed-input error.

    Parameters:

    length - the length of the malformed-input.

    Returns:

    a CoderResult object indicating a malformed-input error.

    Throws:

    IllegalArgumentException - if length is non-positive.

  • unmappableForLength

    public static CoderResult unmappableForLength(int length)
                                           throws IllegalArgumentException

    Gets a CoderResult object indicating an unmappable character error.

    Parameters:

    length - the length of the input unit sequence denoting the unmappable character.

    Returns:

    a CoderResult object indicating an unmappable character error.

    Throws:

    IllegalArgumentException - if length is non-positive.

  • isUnderflow

    public boolean isUnderflow()

    Returns true if this result is an underflow condition.

    Returns:

    true if an underflow, otherwise false.

  • isError

    public boolean isError()

    Returns true if this result represents a malformed-input error or an unmappable-character error.

    Returns:

    true if this is a malformed-input error or an unmappable-character error, otherwise false.

  • isMalformed

    public boolean isMalformed()

    Returns true if this result represents a malformed-input error.

    Returns:

    true if this is a malformed-input error, otherwise false.

  • isOverflow

    public boolean isOverflow()

    Returns true if this result is an overflow condition.

    Returns:

    true if this is an overflow, otherwise false.

  • isUnmappable

    public boolean isUnmappable()

    Returns true if this result represents an unmappable-character error.

    Returns:

    true if this is an unmappable-character error, otherwise false.

  • length

    public int length()
               throws UnsupportedOperationException

    Gets the length of the erroneous input. The length is only meaningful to a malformed-input error or an unmappable character error.

    Returns:

    the length, as an integer, of this object's erroneous input.

    Throws:

    UnsupportedOperationException - if this result is an overflow or underflow.

  • throwException

    public void throwException()
                        throws BufferUnderflowException,
                               BufferOverflowException,
                               UnmappableCharacterException,
                               MalformedInputException,
                               CharacterCodingException

    Throws an exception corresponding to this coder result.

    Throws:

    BufferUnderflowException - in case this is an underflow.

    BufferOverflowException - in case this is an overflow.

    UnmappableCharacterException - in case this is an unmappable-character error.

    MalformedInputException - in case this is a malformed-input error.

    CharacterCodingException - the default exception.

  • toString

    public String toString()

    Returns a text description of this result.

    Overrides:

    toString in class Object

    Returns:

    a text description of this result.
