Object oldValue,
Object newValue,
long lifespanMillis,
long maxIdleTimeMillis)
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
- Parameters:
ctx
- invocation contextvisitor
- visitor to accept
- Returns:
- arbitrary return value
- Throws:
Throwable
- in the event of problems
perform
public Object perform(InvocationContext ctx)
throws Throwable
- Description copied from interface:
ReplicableCommand
- Performs the primary function of the command. Please see specific implementation classes for details on what is
performed as well as return types. Important: this method will be invoked at the end of interceptors chain.
It should never be called directly from a custom interceptor.
- Specified by:
perform
in interface ReplicableCommand
- Parameters:
ctx
- invocation context
- Returns:
- arbitrary return value generated by performing this command
- Throws:
Throwable
- in the event of problems.
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
- Returns:
- the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.
getParameters
public Object[] getParameters()
- Description copied from interface:
ReplicableCommand
- Used by marshallers to stream this command across a network
- Specified by:
getParameters
in interface ReplicableCommand
- Overrides:
getParameters
in class AbstractDataCommand
- Returns:
- an object array of arguments, compatible with pre-2.2.0 MethodCall args.
setParameters
public void setParameters(int commandId,
Object[] parameters)
- Description copied from interface:
ReplicableCommand
- Used by the
CommandsFactory
to create a command from raw data read off a stream.
- Specified by:
setParameters
in interface ReplicableCommand
- Overrides:
setParameters
in class AbstractDataCommand
- Parameters:
commandId
- command id to set. This is usually unused but *could* be used in the event of a command having
multiple IDs, such as PutKeyValueCommand
.parameters
- object array of args
equals
public boolean equals(Object o)
- Overrides:
equals
in class AbstractDataCommand
hashCode
public int hashCode()
- Overrides:
hashCode
in class AbstractDataCommand
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 WriteCommand
- Returns:
- true if the command completed successfully, false otherwise.
getLifespanMillis
public long getLifespanMillis()
getMaxIdleTimeMillis
public long getMaxIdleTimeMillis()
toString
public String toString()
- Overrides:
toString
in class AbstractDataCommand
