Parameters:

table - The encoder table for chars 0x0A-0xFF

Method Detail

encodeChars

public int encodeChars(char[] chars,
                       int off,
                       int len,
                       byte[] buffer,
                       int outputIndex)
                throws CharEncodingException,
                       EncodingBufferFullException

Encode some number of characters into bytes in a buffer. Derived classes may want to override this for better performance.

Overrides:

encodeChars in class CharEncoder

Parameters:

chars - The array of characters to convert

off - The offset into the array of the first character to convert

len - The number of characters to convert

buffer - The byte array in which to store the encoded bytes

outputIndex - The offset into buffer at which to store the encoded bytes

Returns:

The number of bytes stored in the buffer

Throws:

CharEncodingException - If a character could not be encoded

CharEncoderBufferFull - If the passed buffer is too small

EncodingBufferFullException

encodeChar

public int encodeChar(int c,
                      byte[] buffer,
                      int off)
               throws CharEncodingException,
                      EncodingBufferFullException

Implementation of character encoding

Specified by:

encodeChar in class CharEncoder

Parameters:

c - The 32-bit character value to encode

buffer - The byte buffer in which to placed encoded bytes

off - The offset at which to place bytes into the buffer

Returns:

The number of bytes placed in the buffer

Throws:

CharEncodingException - The character could not be encoded in the implemented encoding scheme.

EncodingBufferFullException - There is not enough room in buffer for all the bytes needed to encode the character.
