jdk.util.regex.Matcher
An engine that performs match operations on a java.lang.character sequence by interpreting a Pattern.
A matcher is created from a pattern by invoking the pattern's matcher method. Once created, a matcher can be used to perform three different kinds of match operations:
The matches method attempts to match the entire input sequence against the pattern.
The lookingAt method attempts to match the input sequence, starting at the beginning, against the pattern.
The find method scans the input sequence looking for the next subsequence that matches the pattern.
Each of these methods returns a boolean indicating success or failure. More information about a successful match can be obtained by querying the state of the matcher.
A matcher finds matches in a subset of its input called the region. By default, the region contains all of the matcher's input. The region can be modified via theregion method and queried via the regionStart and regionEnd methods. The way that the region boundaries interact with some pattern constructs can be changed. See useAnchoringBounds and useTransparentBounds for more details.
This class also defines methods for replacing matched subsequences with new strings whose contents can, if desired, be computed from the match result. The appendReplacement and appendTail methods can be used in tandem in order to collect the result into an existing string buffer, or the more convenient replaceAll method can be used to create a string in which every matching subsequence in the input sequence is replaced.
The explicit state of a matcher includes the start and end indices of the most recent successful match. It also includes the start and end indices of the input subsequence captured by each capturing group in the pattern as well as a total count of such subsequences. As a convenience, methods are also provided for returning these captured subsequences in string form.
The explicit state of a matcher is initially undefined; attempting to query any part of it before a successful match will cause an IllegalStateException to be thrown. The explicit state of a matcher is recomputed by every match operation.
The implicit state of a matcher includes the input character sequence as well as the append position, which is initially zero and is updated by the appendReplacement method.
A matcher may be reset explicitly by invoking its reset() method or, if a new input sequence is desired, its reset(CharSequence) method. Resetting a matcher discards its explicit state information and sets the append position to zero.
Instances of this class are not safe for use by multiple concurrent threads.

*quote-replacementclj
(*quote-replacement s)Returns a literal replacement String for the specified String.
This method produces a String that will work as a literal replacement s in the appendReplacement method of the Matcher class. The String produced will match the sequence of characters in s treated as a literal sequence. Slashes ('') and dollar signs ('$') will be given no special meaning.
s - The string to be literalized - java.lang.String
returns: A literal string replacement - java.lang.String
Returns a literal replacement String for the specified
String.
This method produces a String that will work
as a literal replacement s in the
appendReplacement method of the Matcher class.
The String produced will match the sequence of characters
in s treated as a literal sequence. Slashes ('\') and
dollar signs ('$') will be given no special meaning.
s - The string to be literalized - `java.lang.String`
returns: A literal string replacement - `java.lang.String`append-replacementclj
(append-replacement this sb replacement)Implements a non-terminal append-and-replace step.
This method performs the following actions:
It reads characters from the input sequence, starting at the
append position, and appends them to the given string buffer. It stops after reading the last character preceding the previous match, that is, the character at index start() - 1.
It appends the given replacement string to the string buffer.
It sets the append position of this matcher to the index of
the last character matched, plus one, that is, to end().
The replacement string may contain references to subsequences captured during the previous match: Each occurrence of ${name} or $g will be replaced by the result of evaluating the corresponding group(name) or group(g) respectively. For $g, the first number after the $ is always treated as part of the group reference. Subsequent numbers are incorporated into g if they would form a legal group reference. Only the numerals '0' through '9' are considered as potential components of the group reference. If the second group matched the string "foo", for example, then passing the replacement string "$2bar" would cause "foobar" to be appended to the string buffer. A dollar sign ($) may be included as a literal in the replacement string by preceding it with a backslash ($).
Note that backslashes () and dollar signs ($) in the replacement string may cause the results to be different than if it were being treated as a literal replacement string. Dollar signs may be treated as references to captured subsequences as described above, and backslashes are used to escape literal characters in the replacement string.
This method is intended to be used in a loop together with the appendTail and find methods. The following code, for example, writes one dog two dogs in the yard to the standard-output stream:
Pattern p = Pattern.compile("cat"); Matcher m = p.matcher("one cat two cats in the yard"); StringBuffer sb = new StringBuffer(); while (m.find()) { m.appendReplacement(sb, "dog"); } m.appendTail(sb); System.out.println(sb.toString());
sb - The target string buffer - java.lang.StringBuffer
replacement - The replacement string - java.lang.String
returns: This matcher - java.util.regex.Matcher
throws: java.lang.IllegalStateException - If no match has yet been attempted, or if the previous match operation failed
Implements a non-terminal append-and-replace step.
This method performs the following actions:
It reads characters from the input sequence, starting at the
append position, and appends them to the given string buffer. It
stops after reading the last character preceding the previous match,
that is, the character at index start() - 1.
It appends the given replacement string to the string buffer.
It sets the append position of this matcher to the index of
the last character matched, plus one, that is, to end().
The replacement string may contain references to subsequences
captured during the previous match: Each occurrence of
${name} or $g
will be replaced by the result of evaluating the corresponding
group(name) or group(g)
respectively. For $g,
the first number after the $ is always treated as part of
the group reference. Subsequent numbers are incorporated into g if
they would form a legal group reference. Only the numerals '0'
through '9' are considered as potential components of the group
reference. If the second group matched the string "foo", for
example, then passing the replacement string "$2bar" would
cause "foobar" to be appended to the string buffer. A dollar
sign ($) may be included as a literal in the replacement
string by preceding it with a backslash (\$).
Note that backslashes (\) and dollar signs ($) in
the replacement string may cause the results to be different than if it
were being treated as a literal replacement string. Dollar signs may be
treated as references to captured subsequences as described above, and
backslashes are used to escape literal characters in the replacement
string.
This method is intended to be used in a loop together with the
appendTail and find methods. The
following code, for example, writes one dog two dogs in the
yard to the standard-output stream:

Matcher m = p.matcher("one cat two cats in the yard");
StringBuffer sb = new StringBuffer();
while (m.find()) {
m.appendReplacement(sb, "dog");
}
m.appendTail(sb);
System.out.println(sb.toString());

returns: This matcher - `java.util.regex.Matcher`
throws: java.lang.IllegalStateException - If no match has yet been attempted, or if the previous match operation failedappend-tailclj
(append-tail this sb)Implements a terminal append-and-replace step.
This method reads characters from the input sequence, starting at the append position, and appends them to the given string buffer. It is intended to be invoked after one or more invocations of the appendReplacement method in order to copy the remainder of the input sequence.

returns: The (possibly empty) subsequence captured by the group
during the previous match, or null if the group
failed to match part of the input - java.lang.String

g, the expressions m.group(g) and
s.substring(m.start(g), m.end(g))
are equivalent.
Capturing groups are indexed from left
to right, starting at one. Group zero denotes the entire pattern, so
the expression m.group(0) is equivalent to m.group().
If the match was successful but the group specified failed to match
any part of the input sequence, then null is returned. Note
that some groups, for example (a*), match the empty string.
This method will return the empty string when such a group successfully
matches the empty string in the input.

The matcher's position in the input is maintained and its last append position is unaffected. new-pattern - The new pattern used by this matcher - `java.util.regex.Pattern` returns: This matcher - `java.util.regex.Matcher` throws: java.lang.IllegalArgumentException - If newPattern is null
use-transparent-boundsclj
(use-transparent-bounds this b)Sets the transparency of region bounds for this matcher.
Invoking this method with an argument of true will set this matcher to use transparent bounds. If the boolean argument is false, then opaque bounds will be used.
Using transparent bounds, the boundaries of this matcher's region are transparent to lookahead, lookbehind, and boundary matching constructs. Those constructs can see beyond the boundaries of the region to see if a match is appropriate.
Using opaque bounds, the boundaries of this matcher's region are opaque to lookahead, lookbehind, and boundary matching constructs that may try to see beyond them. Those constructs cannot look past the boundaries so they will fail to match anything outside of the region.
By default, a matcher uses opaque bounds.
b - a boolean indicating whether to use opaque or transparent regions - boolean
returns: this matcher - java.util.regex.Matcher
