public class LCSDetectionHTMLReader
extends LCSDetectionReader

The LCSDetectionHTMLReader class extends the LCSDetectionReader class to support the language/encoding detection for input in HTML format.

You can choose the character set of the HTML meta value or the detected character set value as the input character set with the flag METAVAL or DETECTVAL. The default flag value is DETECTVAL.

The detection sampling length indicates how many bytes of plain text on which the detection feature will perform. The default sampling length is 1K. Generally, LCSD handles the language/encoding detection, and you do not need to set this value. By allowing changes to this value, you can control the detection sampling length.

You can get the detection results from the LCSDResultSet class if needed.

Any read method returns UTFDataFormatException if the source is UTF-8 data and an invalid UTF-8 sequence is found.

Since:

10.2

Constructor Detail

LCSDetectionHTMLReader

public LCSDetectionHTMLReader(InputStream in)
                       throws IOException,
                              UTFDataFormatException

Creates an LCSDetectionHTMLReader object. Use the default sampling length and default profile for detection. The detected character set is used for conversion.

Parameters:

in - input stream that you want to detect

Throws:

IOException - if any I/O error occurs

UTFDataFormatException - if any invalid UTF-8 data sequence is detected. Note this occurs only if the source is UTF-8 data

LCSDetectionHTMLReader

public LCSDetectionHTMLReader(InputStream in,
                              int len)
                       throws IOException,
                              UTFDataFormatException

Creates an LCSDetectionHTMLReader object. Use the specified sampling length and default profile for detection. The detected character set is used for conversion.

Parameters:

in - input stream that you want to detect

len - the sampling length

Throws:

IOException - if any I/O error occurs

UTFDataFormatException - if any invalid UTF-8 data sequence is detected. Note this occurs only if the source is UTF-8 data

LCSDetectionHTMLReader

public LCSDetectionHTMLReader(InputStream in,
                              int len,
                              int flag)
                       throws IOException,
                              UTFDataFormatException

Creates an LCSDetectionHTMLReader object. Use the specified sampling length and default profile for detection. The detected character set is used for conversion if the flag is DETECTVAL or the meta value of the character set is used for conversion if the flag is METAVAL.

Parameters:

in - input stream that you want to detect

len - the sampling length

flag - METAVAL or DETECTVAL

Throws:

IOException - if any I/O error occurs

UTFDataFormatException - if any invalid UTF-8 data sequence is detected. Note this occurs only if the source is UTF-8 data
