Method Detail

getPk

public PK getPk()

createKey

public java.lang.Object[] createKey()

Specified by:

createKey in class AbstractCacheUnit

compute

public abstract java.lang.Object compute()

Specified by:

compute in class AbstractCacheUnit

invalidate

public void invalidate(int invalidationType)

Description copied from class: AbstractCacheUnit

mark the Cache Unit to be invalidated upon commit invalidationType is one of the constants (modified or remove)

Overrides:

invalidate in class AbstractCacheUnit

setCacheBoundFalse

public void setCacheBoundFalse()

removedFromCache

public void removedFromCache()

Overrides:

removedFromCache in class AbstractCacheUnit

addedToCacheBeforeComputation

public void addedToCacheBeforeComputation()

Overrides:

addedToCacheBeforeComputation in class AbstractCacheUnit

getCached

public java.lang.Object getCached()

get the cached object from this cache unit. if it is not yet computed, this method blocks until it's computed.

helper method which does exactly the same as AbstractCacheUnit.get(), but catches the exception and throws a RuntimeException (JaloSystemException) instead. because of that you don't have to add a try/catch block in your code.

Returns:

the object

isStillInCache

public boolean isStillInCache()
