Definition qgis.h:3132
A collection of string replacements (specified using QgsStringReplacement objects).
void setReplacements(const QList< QgsStringReplacement > &replacements)
Sets the list of string replacements in this collection.
QgsStringReplacementCollection(const QList< QgsStringReplacement > &replacements=QList< QgsStringReplacement >())
Constructor for QgsStringReplacementCollection.
QList< QgsStringReplacement > replacements() const
Returns the list of string replacements in this collection.
A representation of a single string replacement.
bool wholeWordOnly() const
Returns true if match only applies to whole words, or false if partial word matches are permitted.
QString replacement() const
Returns the string to replace matches with.
bool caseSensitive() const
Returns true if match is case sensitive.
bool operator==(const QgsStringReplacement &other) const
QString match() const
Returns the string matched by this object.
Utility functions for working with strings.
