269 friend class TestQgsImageCache;
A QObject derived base class for QgsAbstractContentCache.
Base class for entries in a QgsAbstractContentCache.
virtual int dataSize() const =0
Returns the memory usage in bytes for the entry.
virtual void dump() const =0
Dumps debugging strings containing the item's properties.
virtual bool isEqual(const QgsAbstractContentCacheEntry *other) const =0
Tests whether this entry matches another entry.
Abstract base class for file content caches, such as SVG or raster image caches.
