Method Detail

getSegment

public int getSegment()

Description copied from interface: SegmentSpecificCommand

Returns the segment that this key maps to. This must always return a number 0 or larger.

Specified by:

getSegment in interface SegmentSpecificCommand

Returns:

the segment of the key

getTopologyId

public int getTopologyId()

Specified by:

getTopologyId in interface TopologyAffectedCommand

setTopologyId

public void setTopologyId(int topologyId)

Specified by:

setTopologyId in interface TopologyAffectedCommand

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(Set) 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

getKey

public Object getKey()

Specified by:

getKey in interface DataCommand

setKey

public void setKey(Object key)

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

isReturnValueExpected

public boolean isReturnValueExpected()

Description copied from interface: ReplicableCommand

If true, a return value will be provided when performed remotely. Otherwise, a remote ResponseGenerator may choose to simply return null to save on marshalling costs.

Specified by:

isReturnValueExpected in interface ReplicableCommand

Returns:

true or false

printFlags

protected final String printFlags()
