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.

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

`fileModified`	Timestamp when file was last modified
`fileModifiedLastCheckTimer`	Time since last check of file modified date
`mFileModifiedCheckTimeout`	Timeout before re-checking whether the file modified date has changed.
`nextEntry`	Entries are kept on a linked list, sorted by last access.
`path`	Represents the absolute path to a file, a remote URL, or a base64 encoded string.
`previousEntry`	Entries are kept on a linked list, sorted by last access.

class qgis.core.QgsAbstractContentCacheEntry[source]¶

Bases: object

__init__(path: str | None)

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

Parameters:: path (Optional[str])

dataSize(self) → int[source]¶

Returns the memory usage in bytes for the entry.

Return type:: int

dump(self)[source]¶: Dumps debugging strings containing the item’s properties. For testing purposes only.

fileModified¶: Timestamp when file was last modified

fileModifiedLastCheckTimer¶: Time since last check of file modified date

isEqual(self, other: QgsAbstractContentCacheEntry | None) → bool[source]¶

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¶: Timeout before re-checking whether the file modified date has changed.

nextEntry¶: Entries are kept on a linked list, sorted by last access. This point refers to the next entry in the cache.

path¶: Represents the absolute path to a file, a remote URL, or a base64 encoded string.

previousEntry¶: Entries are kept on a linked list, sorted by last access. This point refers to the previous entry in the cache.
