getTableOperationType

public TableProcedureInterface.TableOperationType getTableOperationType()

Deprecated.

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.

Returns:

the operation type that the procedure is executing.
