Method Summary

Modifier and Type	Method	Description
void	addInvalidationCallback(java.lang.Runnable callback)	Adds a callback that is invoked when an underlying tracked resource has changed.
void	addInvalidationCallback(java.util.function.Function<java.util.List<java.lang.String>,java.util.List<java.lang.String>> function)	Adds a callback, as a function that receives a list of strings and also returns a list of strings, that is invoked when one or more listed underlying tracked resource have changed.
void	addInvalidationListener(InvalidationListener listener)	Adds a listener, who needs to know when an underlying resource of a given category has changed (so that the receiver may discard any cached data that may have been invalidated).
void	clearOnInvalidation(java.util.Map<?,?> map)	Adds a callback that clears the map.
void	fireInvalidationEvent(java.util.List<java.lang.String> resources)	Notify resource-specific invalidations to listeners.
java.lang.String	getDigest(Resource resource)	Returns the digest for the given path.
boolean	requiresDigest(Resource resource)	Returns true if the path requires that the client URL for the resource include a digest to validate that the client is authorized to access the resource.

Method Detail

getDigest

public java.lang.String getDigest(Resource resource)

Description copied from interface: ResourceDigestManager

Returns the digest for the given path. As of 5.4, simple returns null.

Specified by:

getDigest in interface ResourceDigestManager

Returns:

the digest, or null if the resource does not exist

requiresDigest

public boolean requiresDigest(Resource resource)

Description copied from interface: ResourceDigestManager

Returns true if the path requires that the client URL for the resource include a digest to validate that the client is authorized to access the resource. As of 5.4, simply returns false.

Specified by:

requiresDigest in interface ResourceDigestManager

Returns:

true if digest is required for the resource

addInvalidationListener

public void addInvalidationListener(InvalidationListener listener)

Description copied from interface: InvalidationEventHub

Adds a listener, who needs to know when an underlying resource of a given category has changed (so that the receiver may discard any cached data that may have been invalidated). Does nothing in production mode.

Specified by:

addInvalidationListener in interface InvalidationEventHub

addInvalidationCallback

public void addInvalidationCallback(java.lang.Runnable callback)

Description copied from interface: InvalidationEventHub

Adds a callback that is invoked when an underlying tracked resource has changed. Does nothing in production mode.

Specified by:

addInvalidationCallback in interface InvalidationEventHub

clearOnInvalidation

public void clearOnInvalidation(java.util.Map<?,?> map)

Description copied from interface: InvalidationEventHub

Adds a callback that clears the map.

Specified by:

clearOnInvalidation in interface InvalidationEventHub

addInvalidationCallback

public void addInvalidationCallback(java.util.function.Function<java.util.List<java.lang.String>,java.util.List<java.lang.String>> function)

Description copied from interface: InvalidationEventHub

Adds a callback, as a function that receives a list of strings and also returns a list of strings, that is invoked when one or more listed underlying tracked resource have changed. An empty list should be considered as all resources being changed and any caches needing to be cleared. The return value of the function should be a non-null, but possibly empty, list of other resources that also need to be invalidated in a recursive fashion. This method does nothing in production mode.

Specified by:

addInvalidationCallback in interface InvalidationEventHub

fireInvalidationEvent

public void fireInvalidationEvent(java.util.List<java.lang.String> resources)

Description copied from interface: InvalidationEventHub

Notify resource-specific invalidations to listeners.

Specified by:

fireInvalidationEvent in interface InvalidationEventHub
