Method Details

allIgnorable

public boolean allIgnorable(String s)

Description copied from interface: RbnfLenientScanner

Returns true if a string consists entirely of ignorable characters.

Specified by:

allIgnorable in interface RbnfLenientScanner

Parameters:

s - The string to test

Returns:

true if the string is empty or consists entirely of characters that are ignorable.

findText

public int[] findText(String str,
 String key,
 int startingAt)

Description copied from interface: RbnfLenientScanner

Searches a string for another string. This might use a Collator to compare strings, or just do a simple match.

Specified by:

findText in interface RbnfLenientScanner

Parameters:

str - The string to search

key - The string to search "str" for

startingAt - The index into "str" where the search is to begin

Returns:

A two-element array of ints. Element 0 is the position of the match, or -1 if there was no match. Element 1 is the number of characters in "str" that matched (which isn't necessarily the same as the length of "key")

findText2

public int[] findText2(String str,
 String key,
 int startingAt)

CLOVER:OFF

prefixLength

public int prefixLength(String str,
 String prefix)

CLOVER:ON

Specified by:

prefixLength in interface RbnfLenientScanner

Parameters:

str - The string being tested

prefix - The text we're hoping to see at the beginning of "str"

Returns:

the number of characters in "str" that were matched
