Constructor Detail

LCSDetector

public LCSDetector()

Constructor. Uses the standard default profile

LCSDetector

public LCSDetector(String name)

Constructor which takes a profile name allows user to choose a different profile other than the default

Parameters:

name - name of profile to use

Method Detail

setCharacterSetFilter

public int setCharacterSetFilter(String charset)

Set character set filter if user know the character set of the input data. The default value is none. if both language filter and character set filter are set, they will be ignored. If invalid ISO character set name is passed in, it will be ignored.

Parameters:

charset - ISO character set name.

setLanguageFilter

public int setLanguageFilter(String language)

Set language filter if user knows the language of the input data. The default value is none. If both language filter and character set filter are set, they will be ignored. If invalid language name is passed in, it will be ignored.

detect

public void detect(byte[] input)

Statistical data is cumulated in an internal structure when the detect() methods are called. Use reset() to clear the cumulated statictics.

Parameters:

input - the bytes to be sampled by detect

detect

public int detect(byte[] input,
                  int offset,
                  int length)

Statistical data is cumulated in an internal structure when the detect() methods are called. Use reset() to clear the cumulated statictics. Only the specified length of bytes will be sampled

Parameters:

input - the bytes to be sampled by detect

offset - the index of the first byte to sample

length - the number of bytes to sample

Returns:

the number of bytes smapled, or -1 if the end of the array reached(?)

detect

public void detect(InputStream input)
            throws IOException

Statistical data is cumulated in an internal structure when the detect() methods are called. Use reset() to clear the cumulated statistics. The entire stream will be sampled by detect.

Parameters:

input - inputStream to be sampled by detect

Throws:

IOException - if error occurs while doing operation on stream

detect

public int detect(InputStream input,
                  int length)
           throws IOException

Statistical data is cumulated in an internal structure when the detect() methods are called. Use reset() to clear the cumulated statistics. Only the specified length of bytes will be sampled

Parameters:

input - inputStream to be sampled by detect

length - the number of bytes to sample

Returns:

the number of bytes sampled, or -1 if the end of the stream is reached

Throws:

IOException - if error occurs while doing operation on stream

detect

public void detect(String input)

Statistical data is cumulated in an internal structure when the detect() methods are called. Use reset() to clear the cumulated statistics. The entire String will be sampled by detect.

detect

public int detect(String input,
                  int length)

Statistical data is cumulated in an internal structure when the detect() methods are called. Use reset() to clear the cumulated statistics. Only the specified length of chars will be sampled

Parameters:

input - a string to be sampled by detect

length - the number of chars to sample

Returns:

the number of chars sampled, or -1 if the end of the String is reached

detect

public void detect(char[] input)

Statistical data is cumulated in an internal structure when the detect() methods are called. Use reset() to clear the cumulated statistics. The entire array will be sampled by detect

Parameters:

input - the chars to be sampled by detect

detect

public int detect(char[] input,
                  int offset,
                  int length)

Statistical data is cumulated in an internal structure when the detect() methods are called. Use reset() to clear the cumulated statistics. Only the specified length of chars will be sampled

Parameters:

input - the char array to be sampled by detect

offset - the index of the first char to sample

length - the number of chars to sample

Returns:

the number ofchars sampled, or -1 if the end of the array reached

getResult

public oracle.i18n.lcsd.LCSDResultSet getResult()

Determines the high hit language/character set pairs from the cumulated statistical data

Returns:

a LCSDResultSet object which contains the result

reset

public void reset()

To resetstatistical data for all pairs to 0.
