Member Function Documentation

int NdbEventOperationImpl::execute

(

)

Activates the NdbEventOperation to start receiving events. The changed attribute values may be retrieved after Ndb::nextEvent() has returned not NULL. The getValue() methods must be called prior to execute().

Returns

0 if successful otherwise -1.

Reimplemented from NdbEventOperation.

Definition at line 570 of file NdbEventOperationImpl.cpp.

Here is the caller graph for this function:

Uint32 NdbEventOperationImpl::getAnyValue

(

)

const

Retrieve the AnyValue of the latest retrieved event

Returns

AnyValue

Reimplemented from NdbEventOperation.

Definition at line 784 of file NdbEventOperationImpl.cpp.

Here is the caller graph for this function:

const NdbError & NdbEventOperationImpl::getNdbError

(

)

const

Get the latest error

Returns

Error object.

Reimplemented from NdbEventOperation.

Definition at line 73 of file Ndberr.cpp.

Here is the caller graph for this function:

NdbEventOperation::State NdbEventOperationImpl::getState

(

)

Retrieve current state of the NdbEventOperation object

Reimplemented from NdbEventOperation.

Definition at line 228 of file NdbEventOperationImpl.cpp.

Here is the caller graph for this function:

Uint64 NdbEventOperationImpl::getTransId

(

)

const

Retrieve the TransId of the latest retrieved event

Only valid for data events. If the kernel does not support transaction ids with events, the max Uint64 value is returned.

Returns

TransId

Reimplemented from NdbEventOperation.

Definition at line 796 of file NdbEventOperationImpl.cpp.

Here is the caller graph for this function:

bool NdbEventOperationImpl::tableFragmentationChanged

(

)

const

Check if table fragmentation has changed, for event TE_ALTER

Reimplemented from NdbEventOperation.

Definition at line 765 of file NdbEventOperationImpl.cpp.

Here is the caller graph for this function:

bool NdbEventOperationImpl::tableFrmChanged

(

)

const

Check if table frm has changed, for event TE_ALTER

Reimplemented from NdbEventOperation.

Definition at line 760 of file NdbEventOperationImpl.cpp.

Here is the caller graph for this function:

bool NdbEventOperationImpl::tableNameChanged

(

)

const

Check if table name has changed, for event TE_ALTER

Reimplemented from NdbEventOperation.

Definition at line 755 of file NdbEventOperationImpl.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

bool NdbEventOperationImpl::tableRangeListChanged

(

)

const
