Class MountItemsPool

java.lang.Object

com.facebook.rendercore.MountItemsPool

public class MountItemsPool
extends java.lang.Object

Pools of recycled resources.

FUTURE: Consider customizing the pool implementation such that we can match buffer sizes. Without this we will tend to expand all buffers to the largest size needed.

Field Detail

sIsManualCallbacks

public static boolean sIsManualCallbacks

To support Gingerbread (where the registerActivityLifecycleCallbacks API doesn't exist), we allow apps to explicitly invoke activity callbacks. If this is enabled we'll throw if we are passed a context for which we have no record.

isPoolingDisabled

public static boolean isPoolingDisabled

Should be used to disable pooling entirely for debugging, testing, and other use cases.

Method Detail

acquireMountContent

public static java.lang.Object acquireMountContent(Context context,
                                                   ContentAllocator poolableMountContent)

release

public static void release(Context context,
                           ContentAllocator poolableMountContent,
                           java.lang.Object mountContent)

maybePreallocateContent

public static void maybePreallocateContent(Context context,
                                           ContentAllocator poolableMountContent)

prefillMountContentPool

public static void prefillMountContentPool(Context context,
                                           int poolSize,
                                           ContentAllocator poolableMountContent)

Can be called to fill up a mount content pool for the specified MountContent types. If a pool doesn't exist for a Mount Content type, a default one will be created with the specified size. PoolSize will only be respected if the RenderUnit does not provide a custom Pool implementation.

clear

public static void clear()

acquireHostMountContent

public static java.lang.Object acquireHostMountContent(Context context,
                                                       IBinder windowToken,
                                                       ContentAllocator hostContentProvider)

releaseHostMountContent

public static void releaseHostMountContent(Context context,
                                           IBinder windowToken,
                                           ContentAllocator hostContentProvider,
                                           java.lang.Object content)
