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()

List of all members, including inherited members

Abstract Methods

dataSize	Returns the memory usage in bytes for the entry.
dump	Dumps debugging strings containing the item's properties.
isEqual	Tests whether this entry matches another entry.

Attributes

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
