                         throws java.lang.InterruptedException

Throws:

isRollbackSupported

protected boolean isRollbackSupported(TruncateTableState state)

getState

protected TruncateTableState getState(int stateId)

getStateId

protected int getStateId(TruncateTableState state)

getInitialState

protected TruncateTableState getInitialState()

getTableName

public TableName getTableName()

Specified by:

getTableName in interface TableProcedureInterface

Specified by:

getTableName in class AbstractStateMachineTableProcedure<TruncateTableState>

Returns:

the name of the table the procedure is operating on

getTableOperationType

public TableProcedureInterface.TableOperationType getTableOperationType()

Description copied from interface: TableProcedureInterface

Given an operation type we can take decisions about what to do with pending operations. e.g. if we get a delete and we have some table operation pending (e.g. add column) we can abort those operations.

Specified by:

getTableOperationType in interface TableProcedureInterface

Specified by:

getTableOperationType in class AbstractStateMachineTableProcedure<TruncateTableState>

Returns:

the operation type that the procedure is executing.

toStringClassDetails

public void toStringClassDetails(java.lang.StringBuilder sb)

Overrides:

toStringClassDetails in class AbstractStateMachineTableProcedure<TruncateTableState>

serializeStateData

protected void serializeStateData(ProcedureStateSerializer serializer)
                           throws java.io.IOException

Throws:

java.io.IOException

deserializeStateData

protected void deserializeStateData(ProcedureStateSerializer serializer)
                             throws java.io.IOException

Throws:

java.io.IOException
