matches
public boolean matches(char c) Description copied from class:CharMatcher
Determines a true or false value for the given character.- Specified by:
matches
in classCharMatcher
-
indexIn
Description copied from class:CharMatcher
Returns the index of the first matching BMP character in a character sequence, or-1
if no matching character is present.The default implementation iterates over the sequence in forward order calling
CharMatcher.matches(char)
for each character.- Overrides:
indexIn
in classCharMatcher
- Parameters:
sequence
- the character sequence to examine from the beginning- Returns:
- an index, or
-1
if no character matches
-
indexIn
Description copied from class:CharMatcher
Returns the index of the first matching BMP character in a character sequence, starting from a given position, or-1
if no character matches after that position.The default implementation iterates over the sequence in forward order, beginning at
start
, callingCharMatcher.matches(char)
for each character.- Overrides:
indexIn
in classCharMatcher
- Parameters:
sequence
- the character sequence to examinestart
- the first index to examine; must be nonnegative and no greater thansequence.length()
- Returns:
- the index of the first matching character, guaranteed to be no less than
start
, or-1
if no character matches
-
lastIndexIn
Description copied from class:CharMatcher
Returns the index of the last matching BMP character in a character sequence, or-1
if no matching character is present.The default implementation iterates over the sequence in reverse order calling
CharMatcher.matches(char)
for each character.- Overrides:
lastIndexIn
in classCharMatcher
- Parameters:
sequence
- the character sequence to examine from the end- Returns:
- an index, or
-1
if no character matches
-
matchesAllOf
Description copied from class:CharMatcher
Returnstrue
if a character sequence contains only matching BMP characters.The default implementation iterates over the sequence, invoking
CharMatcher.matches(char)
for each character, until this returnsfalse
or the end is reached.- Overrides:
matchesAllOf
in classCharMatcher
- Parameters:
sequence
- the character sequence to examine, possibly empty- Returns:
true
if this matcher matches every character in the sequence, including when the sequence is empty
-
matchesNoneOf
Description copied from class:CharMatcher
Returnstrue
if a character sequence contains no matching BMP characters. Equivalent to!matchesAnyOf(sequence)
.The default implementation iterates over the sequence, invoking
CharMatcher.matches(char)
for each character, until this returnstrue
or the end is reached.- Overrides:
matchesNoneOf
in classCharMatcher
- Parameters:
sequence
- the character sequence to examine, possibly empty- Returns:
true
if this matcher matches no characters in the sequence, including when the sequence is empty
-
removeFrom
Description copied from class:CharMatcher
Returns a string containing all non-matching characters of a character sequence, in order. For example:
... returnsCharMatcher.is('a').removeFrom("bazaar")
"bzr"
.- Overrides:
removeFrom
in classCharMatcher
-
replaceFrom
Description copied from class:CharMatcher
Returns a string copy of the input character sequence, with each matching BMP character replaced by a given replacement character. For example:
... returnsCharMatcher.is('a').replaceFrom("radar", 'o')
"rodor"
.The default implementation uses
CharMatcher.indexIn(CharSequence)
to find the first matching character, then iterates the remainder of the sequence callingCharMatcher.matches(char)
for each character.- Overrides:
replaceFrom
in classCharMatcher
- Parameters:
sequence
- the character sequence to replace matching characters inreplacement
- the character to append to the result string in place of each matching character insequence
- Returns:
- the new string
-
replaceFrom
Description copied from class:CharMatcher
Returns a string copy of the input character sequence, with each matching BMP character replaced by a given replacement sequence. For example:
... returnsCharMatcher.is('a').replaceFrom("yaha", "oo")
"yoohoo"
.Note: If the replacement is a fixed string with only one character, you are better off calling
CharMatcher.replaceFrom(CharSequence, char)
directly.- Overrides:
replaceFrom
in classCharMatcher
- Parameters:
sequence
- the character sequence to replace matching characters inreplacement
- the characters to append to the result string in place of each matching character insequence
- Returns:
- the new string
-
collapseFrom
Description copied from class:CharMatcher
Returns a string copy of the input character sequence, with each group of consecutive matching BMP characters replaced by a single replacement character. For example:
... returnsCharMatcher.anyOf("eko").collapseFrom("bookkeeper", '-')
"b-p-r"
.The default implementation uses
CharMatcher.indexIn(CharSequence)
to find the first matching character, then iterates the remainder of the sequence callingCharMatcher.matches(char)
for each character.- Overrides:
collapseFrom
in classCharMatcher
- Parameters:
sequence
- the character sequence to replace matching groups of characters inreplacement
- the character to append to the result string in place of each group of matching characters insequence
- Returns:
- the new string
-
trimFrom
Description copied from class:CharMatcher
Returns a substring of the input character sequence that omits all matching BMP characters from the beginning and from the end of the string. For example:
... returnsCharMatcher.anyOf("ab").trimFrom("abacatbab")
"cat"
.Note that:
... is equivalent toCharMatcher.inRange('\0', ' ').trimFrom(str)
String.trim()
.- Overrides:
trimFrom
in classCharMatcher
-
countIn
Description copied from class:CharMatcher
Returns the number of matchingchar
s found in a character sequence.Counts 2 per supplementary character, such as for
CharMatcher.whitespace()
().CharMatcher.negate()
().- Overrides:
countIn
in classCharMatcher
-
and
Description copied from class:CharMatcher
Returns a matcher that matches any character matched by both this matcher andother
.- Overrides:

in classCharMatcher
-
or
Description copied from class:CharMatcher

.- Overrides:

in classCharMatcher
-
negate
Description copied from class:CharMatcher
Returns a matcher that matches any character not matched by this matcher.- Specified by:
negate
in interfacePredicate<Character>
- Overrides:
