All Implemented Interfaces:

ConverterTableInterface

Direct Known Subclasses:

CedictB5ConverterTable, CedictGBConverterTable

public class CedictConverterTable

extends AbstractConverterTable

This class implements the search functions from the ConverterTableInterface. It can search by GB2312, Pinyin, and English. The dictionary entry vector is passed in when construct this class. This class handles the cedict.GB file, and we assume that each line which contains the '[' and ']' is a dictionary entry. If there is a line which contains the '[' and ']' but it's not an entry, then it might cause problem.

Method Detail

init

public void init(ConverterListener listener)
          throws java.io.IOException

Description copied from class: AbstractConverterTable

Initialization method, to be overridden by subclasses.

Specified by:

init in class AbstractConverterTable

java.io.IOException

readInFileByLine

private void readInFileByLine(ConverterListener listener)
                       throws AbortSearchException

Assume that each line in cedict.GB is an entry. Read in cedict.GB byte by byte, and when reach the end of a line, parse the line just read in into a cedictEntry.

AbortSearchException

parseLine

private void parseLine(ByteVector linev)
                throws java.io.UnsupportedEncodingException

Parse a line from cedict.GB. When a Chinese word has multiple English definitions, several entries will be created based on the number of English definitions.

Parameters:

linev - a ByteVector contains a line of cedict.GB

java.io.UnsupportedEncodingException

pinyinRoughlyMatches
