Method Summary

Methods

Modifier and Type	Method and Description
boolean	allIgnorable(String s) Returns true if a string consists entirely of ignorable characters.
int[]	findText(String str, String key, int startingAt) Searches a string for another string.
int	prefixLength(String str, String prefix) Matches characters in a string against a prefix and return the number of chars that matched, or 0 if no match.

Method Detail

allIgnorable

boolean allIgnorable(String s)

Returns true if a string consists entirely of ignorable characters.

Parameters:

s - The string to test

Returns:

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

Status:

Stable ICU 4.4.

prefixLength

int prefixLength(String str,
               String prefix)

Matches characters in a string against a prefix and return the number of chars that matched, or 0 if no match. Only primary-order differences are significant in determining whether there's a match. This means that the returned value need not be the same as the length of the prefix.

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

Status:

Stable ICU 4.4.

findText

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

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

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")

Status:

Stable ICU 4.4.
