Constructor Detail

TextMatcher

public TextMatcher(LocaleId locale1,
                   LocaleId locale2)

Creates a new TextMatcher object.

Parameters:

locale1 - locale of the first language.

locale2 - locale of the second language.

Method Detail

minimum

protected static short minimum(int value1,
                               int value2,
                               int value3)

Returns the minimum value between three given values.

Parameters:

value1 - the first given value.

value2 - the second given value.

value3 - the third given value.

Returns:

the minimum value between three given values.

compare

public int compare(TextFragment frag1,
                   TextFragment frag2,
                   int options)

Compare two textFragment content.

Parameters:

frag1 - The base fragment.

frag2 - the fragment to compare against the base fragment.

options - Comparison options.

Returns:

A score between 0 (no match) and 100 (exact match).

prepareBaseTokens

public List<String> prepareBaseTokens(String plainText)

Creates a list of tokens from a string to use with the compareToBaseTokens(String, List, TextFragment).

Parameters:

plainText - the based text.

Returns:

the list of tokens for the given fragment.

compareToBaseTokens

public int compareToBaseTokens(String text1,
                               List<String> tokens1,
                               TextFragment frag2)

Compare a list of tokens to a TextFragment object.

Parameters:

text1 - the original plain text.

tokens1 - the list of tokens.

frag2 - the fragment to compare against list of tokens.

Returns:

A score between 0 (no match) and 100 (exact match).
