Method Details

init

public void init(ComponentRegistry componentRegistry)

Specified by:

init in interface VisitableCommand

getTopologyId

public int getTopologyId()

Specified by:

getTopologyId in interface TopologyAffectedCommand

setTopologyId

public void setTopologyId(int topologyId)

Specified by:

setTopologyId in interface TopologyAffectedCommand

isForwarded

public boolean isForwarded()

setForwarded

public void setForwarded(boolean forwarded)

getValueMatcher

public ValueMatcher getValueMatcher()

Specified by:

getValueMatcher in interface WriteCommand

Returns:

The current value matching policy.

setValueMatcher

public void setValueMatcher(ValueMatcher valueMatcher)

Specified by:

setValueMatcher in interface WriteCommand

Parameters:

valueMatcher - The new value matching policy.

isSuccessful

public boolean isSuccessful()

Description copied from interface: WriteCommand

Some commands may want to provide information on whether the command was successful or not. This is different from a failure, which usually would result in an exception being thrown. An example is a putIfAbsent() not doing anything because the key in question was present. This would result in a isSuccessful() call returning false.

Specified by:

isSuccessful in interface ReplicableCommand

Specified by:

isSuccessful in interface WriteCommand

Returns:

true if the command completed successfully, false otherwise.

isConditional

public boolean isConditional()

Description copied from interface: WriteCommand

Certain commands only work based on a certain condition or state of the cache. For example, ConcurrentMap.putIfAbsent(Object, Object) only does anything if a condition is met, i.e., the entry in question is not already present. This method tests whether the command in question is conditional or not.

Specified by:

isConditional in interface WriteCommand

Returns:

true if the command is conditional, false otherwise

fail

public void fail()

Description copied from interface: WriteCommand

Make subsequent invocations of WriteCommand.isSuccessful() return false.

Specified by:

fail in interface WriteCommand

getFlagsBitSet

public long getFlagsBitSet()

Specified by:

getFlagsBitSet in interface FlagAffectedCommand

Returns:

The command flags. Flags can be modified with FlagAffectedCommand.setFlagsBitSet(long), FlagAffectedCommand.addFlags(long) and FlagAffectedCommand.addFlags(long) methods.

setFlagsBitSet

public void setFlagsBitSet(long bitSet)

Description copied from interface: FlagAffectedCommand

Set the flags, replacing any existing flags.

Specified by:

setFlagsBitSet in interface FlagAffectedCommand

getParams

public Params getParams()

Specified by:

getParams in interface FunctionalCommand<K,V>

setParams

public void setParams(Params params)

getKeyLockOwner

public Object getKeyLockOwner()

Description copied from interface: RemoteLockCommand

It returns the lock owner of the key.

Usually, in transaction caches it is the GlobalTransaction and in non-transactional caches the CommandInvocationId.

Specified by:

getKeyLockOwner in interface RemoteLockCommand

Returns:

the lock owner of the key.

getCommandInvocationId

public CommandInvocationId getCommandInvocationId()

Specified by:

getCommandInvocationId in interface WriteCommand

Returns:

the CommandInvocationId associated to the command.

hasZeroLockAcquisition

public boolean hasZeroLockAcquisition()

Specified by:

hasZeroLockAcquisition in interface RemoteLockCommand

Returns:

it the locks should be acquire with 0 (zero) acquisition timeout.

hasSkipLocking

public boolean hasSkipLocking()

Description copied from interface: RemoteLockCommand

It checks if this command should acquire locks.

Specified by:

hasSkipLocking in interface RemoteLockCommand

Returns:

true if locks should be acquired for the keys in RemoteLockCommand.getKeysToLock().

getKeyDataConversion

public DataConversion getKeyDataConversion()

Specified by:

getKeyDataConversion in interface FunctionalCommand<K,V>

getValueDataConversion

public DataConversion getValueDataConversion()

Specified by:

getValueDataConversion in interface FunctionalCommand<K,V>

getInternalMetadata

public PrivateMetadata getInternalMetadata(Object key)

Specified by:

getInternalMetadata in interface WriteCommand

setInternalMetadata

public void setInternalMetadata(Object key,
 PrivateMetadata internalMetadata)

Specified by:

setInternalMetadata in interface WriteCommand
