Member Function Documentation

ACE_INLINE ACE_Message_Block * OpenDDS::DCPS::BuildChainVisitor::chain

(

)

Accessor to extract the chain, leaving the head_ and tail_ set to 0 as a result.

Definition at line 20 of file BuildChainVisitor.inl.

References DBG_ENTRY_LVL, head_, and tail_.

Referenced by OpenDDS::DCPS::TransportSendStrategy::prepare_packet().

Here is the caller graph for this function:

int OpenDDS::DCPS::BuildChainVisitor::visit_element

(

TransportQueueElement *

element

)

[virtual]

This is the visit_element() method that will be called when the visitation method used is BasicQueue<T>::accept_visitor().

Return 0 if visiting should stop, return 1 to continue visiting.

Reimplemented from OpenDDS::DCPS::BasicQueueVisitor< TransportQueueElement >.
