Method Detail

getCacheDir

public File getCacheDir()

Specified by:

getCacheDir in interface ArtifactCacheMetaData

longRunningOperation

public void longRunningOperation(String operationDisplayName,
                        Runnable action)

Description copied from interface: CacheAccess

Performs some long running operation within an action invoked by CacheAccess.useCache(String, org.gradle.internal.Factory). Releases all locks while the operation is running, and reacquires the locks at the end of the long running operation.

This method is re-entrant, so that an action can call back into this method.

Specified by:

longRunningOperation in interface CacheAccess

useCache

public <T> T useCache(String operationDisplayName,
             Factory<? extends T> action)

Description copied from interface: CacheAccess

Performs some work against the cache. Acquires exclusive locks the appropriate resources, so that the given action is the only action to execute across all processes (including this one). Releases the locks and all resources at the end of the action.

This method is re-entrant, so that an action can call back into this method.

Specified by:

useCache in interface CacheAccess

useCache

public void useCache(String operationDisplayName,
            Runnable action)

Description copied from interface: CacheAccess

Performs some work against the cache. Acquires exclusive locks the appropriate resources, so that the given action is the only action to execute across all processes (including this one). Releases the locks and all resources at the end of the action.

This method is re-entrant, so that an action can call back into this method.

Specified by:

useCache in interface CacheAccess

longRunningOperation

public <T> T longRunningOperation(String operationDisplayName,
                         Factory<? extends T> action)

Description copied from interface: CacheAccess

Performs some long running operation within an action invoked by CacheAccess.useCache(String, org.gradle.internal.Factory). Releases all locks while the operation is running, and reacquires the locks at the end of the long running operation.

This method is re-entrant, so that an action can call back into this method.

Specified by:

longRunningOperation in interface CacheAccess

createCache

public <K,V> PersistentIndexedCache<K,V> createCache(File cacheFile,
                                            Class<K> keyType,
                                            Class<V> valueType)

Description copied from interface: CacheLockingManager

Creates a cache implementation that is managed by this locking manager. This method may be used at any time.

The returned cache may only be used by an action being run from CacheAccess.useCache(String, org.gradle.internal.Factory). In this instance, an exclusive lock will be held on the cache.

The returned cache may not be used by an action being run from CacheAccess.longRunningOperation(String, org.gradle.internal.Factory).

createCache in interface CacheLockingManager
