Method Detail

absentEntry

@Nullable
public Absent<K,V> absentEntry()

Description copied from interface: HashQueryContext

Returns the special absent entry object, if the entry with the queried key is absent in the hash, returns null, if the entry is present. Might acquire InterProcessReadWriteUpdateLock.readLock() before searching for the key, if the context is not locked yet.

Specified by:

absentEntry in interface HashQueryContext<K>

Specified by:

absentEntry in interface MapQueryContext<K,V,R>

Specified by:

absentEntry in interface SetQueryContext<K,R>

Overrides:

absentEntry in class MapQuery<K,V,R>

entryPresent

public boolean entryPresent()

Overrides:

entryPresent in class HashQuery<K>

entry

public ReplicatedMapQuery<K,V,R> entry()

Description copied from interface: HashQueryContext

Returns the entry context, if the entry with the queried key is present in the ChronicleHash, returns null is the entry is absent. Might acquire InterProcessReadWriteUpdateLock.readLock() before searching for the key, if the context is not locked yet.

Specified by:

entry in interface HashQueryContext<K>

Specified by:

entry in interface MapQueryContext<K,V,R>

Specified by:

entry in interface net.openhft.chronicle.map.replication.MapRemoteQueryContext<K,V,R>

Specified by:

entry in interface net.openhft.chronicle.set.replication.SetRemoteQueryContext<K,R>

Specified by:

entry in interface SetQueryContext<K,R>

Overrides:

entry in class MapQuery<K,V,R>

doRemove

public void doRemove()

Description copied from interface: SetEntry

Removes the entry from the ChronicleSet.

This method is the default implementation for SetEntryOperations.remove(SetEntry), which might be customized over the default.

Specified by:

doRemove in interface HashEntry<K>

Specified by:

doRemove in interface MapEntry<K,V>

Specified by:

doRemove in interface SetEntry<K>

Overrides:

doRemove in class HashQuery<K>

doRemoveCompletely

public void doRemoveCompletely()

Description copied from interface: net.openhft.chronicle.hash.replication.ReplicableEntry

Completely remove the entry from the Chronicle hash, not just mark is as deleted, what MapEntry.doRemove() does for Replicated Chronicle hash. After calling this method the entry won't be replicated over to remote Chronicle nodes, as if ReplicableEntry.dropChanged() was called, and incoming entry replication event with the key if this entry will be processed, as the entry have never been present in the Chronicle hash. After calling this method any subsequent call of any method of ReplicableEntry class throws IllegalStateException.

Specified by:

doRemoveCompletely in interface net.openhft.chronicle.hash.replication.ReplicableEntry

See Also:

ChronicleHashBuilderPrivateAPI.cleanupRemovedEntries(boolean), ChronicleHashBuilderPrivateAPI.removedEntryCleanupTimeout(long, TimeUnit)

doReplaceValue

public void doReplaceValue(Data<V> newValue)

Description copied from interface: MapEntry

Replaces the entry's value with the given newValue.

This method is the default implementation for MapEntryOperations.replaceValue( MapEntry, Data), which might be customized over the default.

Specified by:

doReplaceValue in interface MapEntry<K,V>

Overrides:

doReplaceValue in class MapQuery<K,V,R>

Parameters:

newValue - the value to be put into the map instead of the current value
