public final Class PatternProps

extends Object
Class Inheritance
Implements the immutable Unicode properties Pattern_Syntax and Pattern_White_Space. Hardcodes these properties, does not load data, does not depend on other ICU classes.

Note

Both properties include ASCII as well as non-ASCII, non-Latin-1 code points, and both properties only include BMP code points (no supplementary ones). Pattern_Syntax includes some unassigned code points.

Method Summary

Modifier and TypeMethod and Description
public static boolean

Returns:

true if there are no Pattern_White_Space or Pattern_Syntax characters in s.
isIdentifier(CharSequence s)

Tests whether the CharSequence contains a "pattern identifier", that is, whether it contains only non-Pattern_White_Space, non-Pattern_Syntax characters.

public static boolean

Returns:

true if there are no Pattern_White_Space or Pattern_Syntax characters in s between start and (exclusive) limit.
isIdentifier(CharSequence s, int start, int limit)

Tests whether the CharSequence contains a "pattern identifier", that is, whether it contains only non-Pattern_White_Space, non-Pattern_Syntax characters.

public static boolean

Returns:

true if c is a Pattern_Syntax code point.
isSyntax(int c)

public static boolean

Returns:

true if c is a Pattern_Syntax or Pattern_White_Space code point.
isSyntaxOrWhiteSpace(int c)

public static boolean

Returns:

true if c is a Pattern_White_Space character.
isWhiteSpace(int c)

public static int

Returns:

The smallest index at or after i with a Pattern_White_Space or Pattern_Syntax character.
skipIdentifier(CharSequence s, int i)

Skips over a "pattern identifier" starting at index i of the CharSequence.

public static int

Returns:

The smallest index at or after i with a non-white space character.
skipWhiteSpace(CharSequence s, int i)

Skips over Pattern_White_Space starting at index i of the CharSequence.

public static String

Returns:

s except with leading and trailing SpaceChar characters removed.
trimSpaceChar(String s)
