 @Nullable
 String codec)

ForceMergeAction

public ForceMergeAction(StreamInput in)
                 throws IOException

Throws:

IOException

Method Details

parse

public static ForceMergeAction parse(XContentParser parser)

getMaxNumSegments

public int getMaxNumSegments()

getCodec

public String getCodec()

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Specified by:

writeTo in interface Writeable

Throws:

IOException

getWriteableName

public String getWriteableName()

Specified by:

getWriteableName in interface NamedWriteable

isSafeAction

public boolean isSafeAction()

Specified by:

isSafeAction in interface LifecycleAction

Returns:

true if this action is considered safe. An action is not safe if it will produce unwanted side effects or will get stuck when the action configuration is changed while an index is in this action

toXContent

public XContentBuilder toXContent(XContentBuilder builder,
 ToXContent.Params params)
                           throws IOException

Specified by:

toXContent in interface ToXContent

Throws:

IOException

toSteps

public List<Step> toSteps(Client client,
 String phase,
 Step.StepKey nextStepKey)

Description copied from interface: LifecycleAction

converts the LifecycleAction's execution plan into a series of Steps that reference each other to preserve order of operations.

Specified by:

toSteps in interface LifecycleAction

Parameters:

client - the client that will be used by AsyncActionStep and AsyncWaitStep steps

phase - the name of the phase this action is being executed within

nextStepKey - the next step to execute after this action's steps. If null, then there are no further steps to run. It is the responsibility of each LifecycleAction to implement this correctly and not forget to link to this final step so that the policy can continue.

Returns:

an ordered list of steps that represent the execution plan of the action

hashCode

hashCode in class Object

equals

public boolean equals(Object obj)
