All Implemented Interfaces:

    public class QStringMatcher

extends QtJambiObject
implements java.lang.Cloneable

The QStringMatcher class holds a sequence of characters that can be quickly matched in a Unicode string. This class is useful when you have a sequence of QChars that you want to repeatedly match against some strings (perhaps in a loop), or when you want to search for the same sequence of characters multiple times in the same string. Using a matcher object and `indexIn()` is faster than matching a plain QString with QString::indexOf() if repeated matching takes place. This class offers no benefit if you are doing one-off string matches.

Create the QStringMatcher with the QString you want to search for. Then call `indexIn()` on the QString that you want to search.

See also:
  QString, `QByteArrayMatcher`, and `QRegExp`.

Constructor Detail

### QStringMatcher

    public QStringMatcher()

  Constructs an empty string matcher that won't match anything. Call `setPattern()` to give it a pattern to match.

### QStringMatcher

    public QStringMatcher(java.lang.String pattern)

  Constructs a string matcher that will search for `pattern`, with case sensitivity `cs`.

  Call `indexIn()` to perform a search.

### QStringMatcher

    public QStringMatcher(java.lang.String pattern,
                          Qt.CaseSensitivity cs)

  Constructs a string matcher that will search for `pattern`, with case sensitivity `cs`.

  Call `indexIn()` to perform a search.

### QStringMatcher

    public QStringMatcher(QStringMatcher other)

  Copies the `other` string matcher to this string matcher.

Method Detail

### caseSensitivity

    public final Qt.CaseSensitivity caseSensitivity()

  Returns the case sensitivity setting for this string matcher.

See also:
  `setCaseSensitivity()`.

### indexIn

    public final int indexIn(java.lang.String str)

  Searches the string `str` from character position `from` (default 0, i. . from the first character), for the string `pattern()` that was set in the constructor or in the most recent call to `setPattern()`. Returns the position where the `pattern()` matched in `str`, or -1 if no match was found.

See also:
  `setPattern()`, and `setCaseSensitivity()`.

### indexIn

    public final int indexIn(java.lang.String str,
                             int from)

  Searches the string `str` from character position `from` (default 0, i. . from the first character), for the string `pattern()` that was set in the constructor or in the most recent call to `setPattern()`. Returns the position where the `pattern()` matched in `str`, or -1 if no match was found.

See also:
  `setPattern()`, and `setCaseSensitivity()`.

### pattern

    public final java.lang.String pattern()

  Returns the string pattern that this string matcher will search for.

See also:
  `setPattern()`.

### setCaseSensitivity

    public final void setCaseSensitivity(Qt.CaseSensitivity cs)

  Sets the case sensitivity setting of this string matcher to `cs`.

See also:
  `caseSensitivity()`, `setPattern()`, and `indexIn()`.

### setPattern

    public final void setPattern(java.lang.String pattern)

  Sets the string that this string matcher will search for to `pattern`.

See also:
  `pattern()`, `setCaseSensitivity()`, and `indexIn()`.

### clone

    public QStringMatcher clone()

  This method is reimplemented for internal reasons

  Overrides:
    `clone` in class `java.lang.Object`
