getCommandId
public byte getCommandId()Description copied from interface:ReplicableCommand
Used by marshallers to convert this command into an id for streaming.- Returns:
- the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.
-
writeTo
Description copied from interface:ReplicableCommand
Writes this instance to theObjectOutput
.- Parameters:
output
- the stream.- Throws:
IOException
- if an error occurred during the I/O.
-
readFrom
Description copied from interface:ReplicableCommand
Reads this instance from the stream written byReplicableCommand.writeTo(ObjectOutput)
.- 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.
-
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.- Returns:
- true if the command is conditional, false otherwise
-
acceptVisitor
Description copied from interface:VisitableCommand
Accept a visitor, and return the result of accepting this visitor.- Parameters:
ctx
- invocation contextvisitor
- visitor to accept- Returns:
- arbitrary return value
- Throws:
Throwable
- in the event of problems
-
loadType
- Returns:
- Nodes on which the command needs to read the previous values of the keys it acts on.
-
isWriteOnly
public boolean isWriteOnly()Description copied from interface:WriteCommand
Indicates whether the command is write-only, meaning that it makes no attempt to read the previously associated value with key for which the command is directed.- Returns:
- true is the command is write only, false otherwise.
