Method Detail

getLockSetSize

protected final int getLockSetSize()

Specified by:

getLockSetSize in class AbstractContext

hasLockedKey

public boolean hasLockedKey(Object key)

Description copied from interface: EntryLookup

Note that if a transaction is in scope, implementations should test this lock from on TransactionContext. Using this method should always ensure locks checked in the appropriate scope.

Specified by:

hasLockedKey in interface EntryLookup

Overrides:

hasLockedKey in class AbstractContext

Parameters:

key - lock to test

Returns:

true if the lock being tested is already held in the current scope, false otherwise.

lookupEntry

public CacheEntry lookupEntry(Object k)

Description copied from interface: EntryLookup

Retrieves an entry from the collection of looked up entries in the current scope.

If a transaction is in progress, implementations should delegate to the same method in TransactionContext.

Specified by:

lookupEntry in interface EntryLookup

Overrides:

lookupEntry in class AbstractContext

Parameters:

k - key to look up

Returns:

an entry, or null if it cannot be found.

removeLookedUpEntry

public void removeLookedUpEntry(Object key)

Specified by:

removeLookedUpEntry in interface EntryLookup

Overrides:

removeLookedUpEntry in class AbstractContext

putLookedUpEntry

public void putLookedUpEntry(Object key,
                             CacheEntry e)

Description copied from interface: EntryLookup

Puts an entry in the registry of looked up entries in the current scope.

If a transaction is in progress, implementations should delegate to the same method in TransactionContext.

Specified by:

putLookedUpEntry in interface EntryLookup

Overrides:

putLookedUpEntry in class AbstractContext

Parameters:

key - key to store

e - entry to store

putLookedUpEntries

public void putLookedUpEntries(Map<Object,CacheEntry> lookedUpEntries)

Specified by:

putLookedUpEntries in interface EntryLookup

Overrides:

putLookedUpEntries in class AbstractContext

clearLookedUpEntries

public void clearLookedUpEntries()

Description copied from interface: EntryLookup

Clears the collection of entries looked up

Specified by:

clearLookedUpEntries in interface EntryLookup

Overrides:

clearLookedUpEntries in class AbstractContext

getLookedUpEntries

public BidirectionalMap<Object,CacheEntry> getLookedUpEntries()

Description copied from interface: EntryLookup

Retrieves a map of entries looked up within the current scope.

If a transaction is in progress, implementations should delegate to the same method in TransactionContext.

Specified by:

getLookedUpEntries in interface EntryLookup

Overrides:

getLookedUpEntries in class AbstractContext

Returns:

a map of looked up entries.

copy

public InvocationContext copy()

Specified by:

copy in interface InvocationContext

setLocalRollbackOnly

public void setLocalRollbackOnly(boolean localRollbackOnly)

Marks teh context as only rolling back.

Specified by:
