Class: QgsAbstractContentCacheEntry

Base class for entries in a QgsAbstractContentCache.

Subclasses must take care to correctly implement the isEqual() method, applying their own logic for testing extra cache properties (e.g. image size for an image-based cache).

Added in version 3.6.

Note

This is an abstract class, with methods which must be implemented by a subclass.

The following methods must be implemented: dataSize(), dump(), isEqual()

class qgis.core.QgsAbstractContentCacheEntry

Bases: object

__init__(path: str | None)

Constructor for QgsAbstractContentCacheEntry for an entry relating to the specified path.

Parameters:

path (Optional[str])

abstract dataSize(self) → int

Returns the memory usage in bytes for the entry.

Return type:

int

abstract dump(self)

Dumps debugging strings containing the item’s properties. For testing purposes only.

fileModified: QDateTime

fileModifiedLastCheckTimer: QElapsedTimer

abstract isEqual(self, other: QgsAbstractContentCacheEntry | None) → bool

Tests whether this entry matches another entry. Subclasses must take care to check that the type of other is of a matching class, and then test extra cache-specific properties, such as image size.

Parameters:

other (Optional[QgsAbstractContentCacheEntry])

Return type:

bool

mFileModifiedCheckTimeout: int

nextEntry: QgsAbstractContentCacheEntry

path: str

previousEntry: QgsAbstractContentCacheEntry
