Method Detail

getMaxByteCount

public int getMaxByteCount(char[] forThis,
                           int start,
                           int end)

Description copied from class: CharToByteConverter

Returns the number of bytes that the specified character sequence will require for encoding. For instance, in UTF8 encoding, a character can be encoded as one, two, or three bytes. This method should always be called before the convert() method. The value returned may not be the actual number of converted bytes that will be produced due to conversion errors, but it will be the maximum that will be produced.

Specified by:

getMaxByteCount in class CharToByteConverter

Parameters:

forThis - contains the character sequence that will be encoded to determine the number of bytes required

start - offset into the character array to begin processing

end - ending offset in the character array to end processing. The number of processed characters will then be (end-start).

Returns:

?

convert

public int convert(char[] src,
                   int srcStart,
                   int srcEnd,
                   byte[] dst,
                   int dstStart,
                   int dstEnd)

Description copied from class: CharToByteConverter

Converts the specified char array into a byte array based on this CharToByteConverter's encoding scheme. getMaxByteCount() should always be called first to find out how much room is required in the destination byte array.

Specified by:

convert in class CharToByteConverter

Parameters:

src - the same character array passed to getMaxByteCount()

srcStart - the same starting offset as passed to getMaxByteCount()

srcEnd - the same ending offset as passed to getMaxByteCount()

dst - the destination byte array

dstStart - offset to begin storing converted characters in the destination array

dstEnd - the ending location for storing converted characters into the destination array. This argument may usually be ignored, as the algorithm may choose to continue converting characters until finished.

Returns:

?

flush

public int flush(byte[] buff,
                 int start,
                 int end)

Description copied from class: CharToByteConverter

Tells the CharToByteConverter to convert any unconverted data it has internally stored. Some CharToByteConverter's will store state between calls to convert(). Since the converter may be left in an unknown state, the converter should be flushed to notify it that no more input will be received. The converter can handle any unfinished conversions before its output is used.

Specified by:

flush in class CharToByteConverter

Parameters:

buff - the destination byte array

start - the next available offset into the destination array

end - offset in the destination array to stop placing data (may be ignored by some algorithms)

Returns:

?

CharToByteConverter.convert(char[],int,int,byte[],int,int)

getName

public String getName()

Description copied from class: CharToByteConverter

Returns the name of this encoding scheme. For example, "UTF8".

Specified by:

getName in class CharToByteConverter

Returns:

?
