Inherited Methods

From class sun.io.CharToByteConverter

boolean	canConvert(char c) Returns true if the given character can be converted to the target character encoding.
abstract int	convert(char[] input, int inStart, int inEnd, byte[] output, int outStart, int outEnd) Converts an array of Unicode characters into an array of bytes in the target character encoding.
byte[]	convertAll(char[] input) Converts an array of Unicode characters into an array of bytes in the target character encoding.
int	convertAny(char[] input, int inStart, int inEnd, byte[] output, int outStart, int outEnd)
abstract int	flush(byte[] output, int outStart, int outEnd) Writes any remaining output to the output buffer and resets the converter to its initial state.
int	flushAny(byte[] output, int outStart, int outEnd) Writes any remaining output to the output buffer and resets the converter to its initial state.
int	getBadInputLength() Returns the length, in chars, of the input which caused a MalformedInputException.
abstract String	getCharacterEncoding() Returns the character set id for the conversion.
static CharToByteConverter	getConverter(String encoding) Returns appropriate CharToByteConverter subclass instance.
static CharToByteConverter	getDefault() Create an instance of the default CharToByteConverter subclass.
abstract int	getMaxBytesPerChar() Returns the maximum number of bytes needed to convert a char.
int	nextByteIndex() Returns the index of the byte just past the last byte written by the previous call to convert.
int	nextCharIndex() Returns the index of the character just past the last character successfully converted by the previous call to convert.
abstract void	reset() Resets converter to its initial state.
void	setSubstitutionBytes(byte[] newSubBytes) Sets the substitution bytes to use when the converter is in substitution mode.
void	setSubstitutionMode(boolean doSub) Sets converter into substitution mode.
String	toString() Returns a string representation of the class.

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Fields

protected short[] index1

protected String[] index2

Public Constructors

public CharToByteDoubleByte ()

Public Methods

public boolean canConvert (char ch)

Return whether a character is mappable or not

Parameters

ch	character to test

Returns

true if a character is mappable

public int convert (char[] input, int inOff, int inEnd, byte[] output, int outOff, int outEnd)

Converts characters to sequences of bytes. Conversions that result in Exceptions can be restarted by calling convert again, with appropriately modified parameters.

Parameters

input	char array containing text in Unicode
inOff	begin conversion at this offset in input array.
inEnd	offset of last byte to be converted
output	byte array to receive conversion result
outOff	start writing to output array at this offset.
outEnd	offset of last byte to be written to

Returns

the characters written to output.

Throws

ConversionBufferFullException
MalformedInputException
UnknownCharacterException

public int flush (byte[] output, int outStart, int outEnd)

Writes any remaining output to the output buffer and resets the converter to its initial state.

Parameters

output	byte array to receive flushed output.
outStart	start writing to output array at this offset.
outEnd	stop writing to output array at this offset (exclusive).

Throws

ConversionBufferFullException
MalformedInputException

public short[] getIndex1 ()

public String[] getIndex2 ()

public int getMaxBytesPerChar ()

the maximum number of bytes needed to hold a converted char

public void reset ()

Resets the converter. Call this method to reset the converter to its initial state
