Field Summary

static java.lang.String	IT_CONS
static java.lang.String	IT_VOWELS
int[]	offsets

Constructor Summary

OrthographicRules(java.lang.String ruleset)
Constructor.

Method Summary

int[]	getOffsetTable() Returns the offset table.
static void	main(java.lang.String[] argv) We provide main() so that our services will be available outside Java (i.e., so we can run as a Un*x-style filter).
java.lang.String	normalize(java.lang.String s) Applies the normalization rules in ruleset to s, without offset tracking.
java.lang.String	normalize(java.lang.String s, int[] offsets) Applies the normalization rules in ruleset to s, with offset tracking.

Constructor Detail

OrthographicRules

public OrthographicRules(java.lang.String ruleset)

Constructor.

Parameters:

ruleset - name of rule set to apply

Method Detail

normalize

public java.lang.String normalize(java.lang.String s,
                                  int[] offsets)

Applies the normalization rules in ruleset to s, with offset tracking.

WARNING: Arboreal will not work properly if a normalization substitution replaces a source character with more than two target characters! This is simply a BUG, and should be fixed. Fortunately, however, one does not often need such a replacement.

FIXME: If the orthographic rules eliminate all characters in a word, word counting in ContentRenderPane will not work correctly!

Parameters:

s - source string

offsets - character offset table

Returns:

normalized string

normalize

public java.lang.String normalize(java.lang.String s)

Applies the normalization rules in ruleset to s, without offset tracking.

Parameters:

s - source string

Returns:

normalized string

getOffsetTable

public int[] getOffsetTable()

Returns the offset table.

Returns:

offset table

main

public static void main(java.lang.String[] argv)

We provide main() so that our services will be available outside Java (i.e., so we can run as a Un*x-style filter).
