final class CPCache(delayedQ: ArrayBuffer[() => Unit])

A map-like type that is used by CPSceneObjectContext for game-wide and scene-wide user-data containers.

The instances of this class are created and managed by the game engine and available via CPSceneObjectContext.getSceneCache and CPSceneObjectContext.getGameCache methods. Scene and game caches can be used to exchange and store user-defined data between frames of the same scene or between scenes of the game. Note that by default these caches are in-memory only and not persistent between game executions. One coule, however, add persistence using one of the lifecycle methods available through CPLifecycle type that is extended by both CPSceneObject and CPScene types.

Note that all mutating operations will be queued up and executed at the end of the current frame processing. Specifically, any changes will be "visible" to other scene objects only on the next frame.

Attributes

delayedQ: Queue for delayed operations. Used internally by the game engine.

Concrete methods

Retrieves the value which is associated with the given key.

Attributes

key: The key.
Throws:: NoSuchElementException
Thrown if there is no mapping for given key.
Source:: CPCache.scala

Removes all mappings from this cache.

Note that all mutating operations will be queued up and executed at the end of the current frame processing. Specifically, any changes will be "visible" to other scene objects only on the next frame.

Attributes

Source:: CPCache.scala

Tests whether this cache contains a binding for a key.

Attributes

key: The key.
Source:: CPCache.scala

Retains only those mappings for which the predicate f returns true.

Note that all mutating operations will be queued up and executed at the end of the current frame processing. Specifically, any changes will be "visible" to other scene objects only on the next frame.

Attributes

f: The test predicate.
Source:: CPCache.scala

Optionally returns the value associated with a key.

Attributes

key: Key value.
Returns:: An option value containing the value associated with key in this cache, or None if none exists.
Source:: CPCache.scala

Tests whether the cache is empty.

Attributes

Returns:: true if the cache contains no elements, false otherwise.
Source:: CPCache.scala

Gets iterator can be used only once.

Attributes

Source:: CPCache.scala

Applies a transformation function to all values contained in this cache. The transformation function produces new values from existing keys associated values.

Note that all mutating operations will be queued up and executed at the end of the current frame processing. Specifically, any changes will be "visible" to other scene objects only on the next frame.

Attributes

f: The transformation to apply
Source:: CPCache.scala

Adds a new key/value pair to this cache. If the map already contains a mapping for the key, it will be overridden by the new value.

Note that all mutating operations will be queued up and executed at the end of the current frame processing. Specifically, any changes will be "visible" to other scene objects only on the next frame.

Attributes

key: The key to update.
value: The new value.
Source:: CPCache.scala

Removes a key from this cache.

Note that all mutating operations will be queued up and executed at the end of the current frame processing. Specifically, any changes will be "visible" to other scene objects only on the next frame.

Attributes

key: The key to be removed.
