Class InvocationBuilder

java.lang.Object

com.hazelcast.spi.InvocationBuilder

public abstract class InvocationBuilder
extends Object

The InvocationBuilder is responsible for building an invocation of an operation and invoking it.

The original design exposed the actual Invocation class, but this will limit flexibility since the whole invocation can't be changed or fully removed easily.

Constructor Detail

InvocationBuilder

protected InvocationBuilder(String serviceName,
                 Operation op,
                 int partitionId,
                 Address target)

Creates an InvocationBuilder

Parameters:

serviceName - the name of the service

op - the operation to execute

partitionId - the id of the partition upon which to execute the operation

target - the target machine. Either the partitionId or the target needs to be set.

Method Detail

setReplicaIndex

public InvocationBuilder setReplicaIndex(int replicaIndex)

Sets the replicaIndex.

Parameters:

replicaIndex - the replica index

Returns:

the InvocationBuilder

Throws:

IllegalArgumentException - if replicaIndex smaller than 0 or larger than the max replica count.

isResultDeserialized

public boolean isResultDeserialized()

Checks if the Future should automatically deserialize the result. In most cases, you don't want Data to be returned, but the deserialized object. But in some cases, you want to get the raw Data object.

Defaults to true.

Returns:

true if the the result is automatically deserialized, false otherwise.

setResultDeserialized

public InvocationBuilder setResultDeserialized(boolean resultDeserialized)

Sets the automatic deserialized option for the result.

Parameters:

resultDeserialized - true if data

Returns:

the updated InvocationBuilder.

isResultDeserialized()

setTryCount

public InvocationBuilder setTryCount(int tryCount)

Sets the try count; the number of times this operation can be retried.

Parameters:

tryCount - the try count; the number of times this operation can be retried

Returns:

the InvocationBuilder

setTryPauseMillis

public InvocationBuilder setTryPauseMillis(long tryPauseMillis)

Sets the pause time in milliseconds.

Parameters:

tryPauseMillis - the pause time in milliseconds.

Returns:

the InvocationBuilder

setCallTimeout

public InvocationBuilder setCallTimeout(long callTimeout)

getServiceName

public String getServiceName()

Gets the name of the service.

Returns:

the name of the service

getOp

public Operation getOp()

Gets the operation to execute.

Returns:

the operation to execute

getReplicaIndex

public int getReplicaIndex()

Gets the replicaIndex.

Returns:

the replicaIndex

getTryCount

public int getTryCount()

Gets the try count; the number of times this operation can be retried.

Returns:

the try count; the number of times this operation can be retried

getTryPauseMillis

public long getTryPauseMillis()

Gets the pause time in milliseconds.

Returns:

the pause time in milliseconds

getTarget

public Address getTarget()

Returns the target machine.

Returns:

the target machine.

getPartitionId

public int getPartitionId()

Returns the partition id.

Returns:

the partition id.

getCallTimeout

public long getCallTimeout()

getExecutionCallback

public ExecutionCallback<Object> getExecutionCallback()

Gets the ExecutionCallback. If none is set, null is returned.

Returns:

gets the ExecutionCallback.

setExecutionCallback

public InvocationBuilder setExecutionCallback(ExecutionCallback<Object> executionCallback)

Sets the ExecutionCallback.

Parameters:
