static CharPredicate	isNot(char ch)	Returns a CharPredicate that matches except ch.
default boolean	isPrefixOf(CharSequence sequence)	Returns true if sequence starts with a character that matches this predicate.
default boolean	isSuffixOf(CharSequence sequence)	Returns true if sequence ends with a character that matches this predicate.
default boolean	matchesAllOf(CharSequence sequence)	Returns true if a character sequence contains only matching BMP characters.
default boolean	matchesAnyOf(CharSequence sequence)	Returns true if a character sequence contains at least one matching BMP character.
default boolean	matchesNoneOf(CharSequence sequence)	Returns true if a character sequence contains no matching BMP characters.
static CharPredicate	noneOf(String chars)	Returns a CharPredicate that matches any of chars.
default CharPredicate	not()	Returns the negation of this CharPredicate.
default CharPredicate	or(char ch)	Returns a CharPredicate that evaluates true if either this predicate evaluates to true, or the character is ch.
default CharPredicate	or(CharPredicate that)	Returns a CharPredicate that evaluates true if either this or that predicate evaluate to true.
default CharPredicate	orRange(char from, char to)	Returns a CharPredicate that evaluates true if either this predicate evaluates to true, or the character is in the range of [from, to].
static CharPredicate	range(char from, char to)	Returns a CharPredicate for the range of characters: [from, to].
boolean	test(char ch)	Returns true if ch satisfies this predicate.

Method Details

is

static CharPredicate is(char ch)

Returns a CharPredicate for the range of characters: [from, to].

isNot

static CharPredicate isNot(char ch)

Returns a CharPredicate that matches except ch.

range

static CharPredicate range(char from,
 char to)

Returns a CharPredicate for the range of characters: [from, to].

anyOf

static CharPredicate anyOf(String chars)

Returns a CharPredicate that matches any of chars.

noneOf

static CharPredicate noneOf(String chars)

Returns a CharPredicate that matches any of chars.

test

boolean test(char ch)

Returns true if ch satisfies this predicate.

or

default CharPredicate or(CharPredicate that)

Returns a CharPredicate that evaluates true if either this or that predicate evaluate to true.

and

default CharPredicate and(CharPredicate that)

Returns a CharPredicate that evaluates true if both this and that predicate evaluate to true.

or

default CharPredicate or(char ch)

Returns a CharPredicate that evaluates true if either this predicate evaluates to true, or the character is ch.

orRange

default CharPredicate orRange(char from,
 char to)

Returns a CharPredicate that evaluates true if either this predicate evaluates to true, or the character is in the range of [from, to].

not

default CharPredicate not()

Returns the negation of this CharPredicate.

matchesAnyOf

default boolean matchesAnyOf(CharSequence sequence)

Returns true if a character sequence contains at least one matching BMP character. Equivalent to !matchesNoneOf(sequence).

Since:

7.0

matchesAllOf

default boolean matchesAllOf(CharSequence sequence)

Returns true if a character sequence contains only matching BMP characters.

Since:

7.0

matchesNoneOf

default boolean matchesNoneOf(CharSequence sequence)

Returns true if a character sequence contains no matching BMP characters. Equivalent to !matchesAnyOf(sequence).

Since:

7.0

isPrefixOf

default boolean isPrefixOf(CharSequence sequence)

Returns true if sequence starts with a character that matches this predicate.

Since:

9.0

isSuffixOf

default boolean isSuffixOf(CharSequence sequence)

Returns true if sequence ends with a character that matches this predicate.
