Method Details

acceptVisitor

public Object acceptVisitor(InvocationContext ctx,
 Visitor visitor)
                     throws Throwable

Description copied from interface: VisitableCommand

Accept a visitor, and return the result of accepting this visitor.

Specified by:

acceptVisitor in interface VisitableCommand

Overrides:

acceptVisitor in class RemoveCommand

Parameters:

ctx - invocation context

visitor - visitor to accept

Returns:

arbitrary return value

Throws:

Throwable - in the event of problems

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

Overrides:

isConditional in class RemoveCommand

Returns:

true if the command is conditional, false otherwise

getCommandId

public byte getCommandId()

Description copied from interface: ReplicableCommand

Used by marshallers to convert this command into an id for streaming.

Specified by:

getCommandId in interface ReplicableCommand

Overrides:

getCommandId in class RemoveCommand

Returns:

the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.

toString

public String toString()

Overrides:

toString in class RemoveCommand

writeTo

public void writeTo(ObjectOutput output)
             throws IOException

Description copied from interface: ReplicableCommand

Writes this instance to the ObjectOutput.

Specified by:

writeTo in interface ReplicableCommand

Overrides:

writeTo in class RemoveCommand

Parameters:

output - the stream.

Throws:

IOException - if an error occurred during the I/O.

readFrom

public void readFrom(ObjectInput input)
              throws IOException,
ClassNotFoundException

Description copied from interface: ReplicableCommand

Reads this instance from the stream written by ReplicableCommand.writeTo(ObjectOutput).

Specified by:

readFrom in interface ReplicableCommand

Overrides:

readFrom in class RemoveCommand

Parameters:

input - the stream to read.

Throws:

IOException - if an error occurred during the I/O.

ClassNotFoundException - if it tries to load an undefined class.

equals

public boolean equals(Object o)

Overrides:

equals in class RemoveCommand

hashCode

public int hashCode()

Overrides:

hashCode in class RemoveCommand

isMaxIdle

public boolean isMaxIdle()

Whether this remove expired was fired because of max idle

Returns:

if this command is max idle based expiration

getLifespan

public Long getLifespan()

logThrowable

public boolean logThrowable(Throwable t)
