Class PatternProps

java.lang.Object

com.ibm.icu.impl.PatternProps

public final class PatternProps
extends Object

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 Detail

isSyntax

public static boolean isSyntax(int c)

Returns:

true if c is a Pattern_Syntax code point.

isSyntaxOrWhiteSpace

public static boolean isSyntaxOrWhiteSpace(int c)

Returns:

true if c is a Pattern_Syntax or Pattern_White_Space code point.

isWhiteSpace

public static boolean isWhiteSpace(int c)

Returns:

true if c is a Pattern_White_Space character.

skipWhiteSpace

public static int skipWhiteSpace(CharSequence s,
                                 int i)

Skips over Pattern_White_Space starting at index i of the CharSequence.

Returns:

The smallest index at or after i with a non-white space character.

trimWhiteSpace

public static String trimWhiteSpace(String s)

Returns:

s except with leading and trailing Pattern_White_Space removed.

isIdentifier

public static boolean 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.

Returns:

true if there are no Pattern_White_Space or Pattern_Syntax characters in s.

isIdentifier

public static boolean 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.

Returns:

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

skipIdentifier

public static int skipIdentifier(CharSequence s,
                                 int i)

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

Returns:

The smallest index at or after i with a Pattern_White_Space or Pattern_Syntax character.
