Constructor Detail

FailureProcessor

public FailureProcessor(GridKernalContext ctx)

Parameters:

ctx - Context.

Method Detail

start

public void start()
           throws IgniteCheckedException

Starts grid component.

Specified by:

start in interface GridComponent

Overrides:

start in class GridProcessorAdapter

Throws:

IgniteCheckedException - Throws in case of any errors.

nodeStopping

public boolean nodeStopping()

Returns:

@{code True} if a node will be stopped by current handler in near time.

getDefaultFailureHandler

protected FailureHandler getDefaultFailureHandler()

This method is used to initialize local failure handler if IgniteConfiguration doesn't contain configured one.

Returns:

Default FailureHandler implementation.

failureContext

public FailureContext failureContext()

Returns:

Failure context.

process

public boolean process(FailureContext failureCtx)

Processes failure accordingly to configured FailureHandler.

Parameters:

failureCtx - Failure context.

Returns:

True If this very call led to Ignite node invalidation.

process

public boolean process(FailureContext failureCtx,
                       FailureHandler hnd)

Processes failure accordingly to given failure handler.

Parameters:

failureCtx - Failure context.

hnd - Failure handler.

Returns:

True If this very call led to Ignite node invalidation.
