Member Function Documentation

onInputChange()

virtual void jlm::rvsdg::RegionObserver::onInputChange ( Input *  input, Output *  old_origin, Output *  new_origin  )

pure virtual

Called right after the given input gets a new origin.

Parameters

input	the input.
old_origin	the input's old origin.
new_origin	the input's new origin.

Implemented in jlm::rvsdg::detail::ForwardingObserver< Traverser >, jlm::rvsdg::detail::ForwardingObserver< BottomUpTraverserGeneric >, jlm::rvsdg::detail::ForwardingObserver< TopDownTraverserGeneric >, and jlm::rvsdg::RecordingObserver.

onInputCreate()

virtual void jlm::rvsdg::RegionObserver::onInputCreate ( Input *  input )

pure virtual

Called after a node gets a new input, or the region gets a new result. This method is not called when creating new nodes, only modifying existing nodes.

Parameters

input

the new input

Implemented in jlm::rvsdg::detail::ForwardingObserver< Traverser >, jlm::rvsdg::detail::ForwardingObserver< BottomUpTraverserGeneric >, jlm::rvsdg::detail::ForwardingObserver< TopDownTraverserGeneric >, and jlm::rvsdg::RecordingObserver.

onInputDestroy()

virtual void jlm::rvsdg::RegionObserver::onInputDestroy ( Input *  input )

pure virtual

Called right before a node input or region result is removed. This method is not called when deleting nodes, only modifying existing nodes.

Parameters

input

the input that is removed

Implemented in jlm::rvsdg::detail::ForwardingObserver< Traverser >, jlm::rvsdg::detail::ForwardingObserver< BottomUpTraverserGeneric >, jlm::rvsdg::detail::ForwardingObserver< TopDownTraverserGeneric >, and jlm::rvsdg::RecordingObserver.

onNodeCreate()

virtual void jlm::rvsdg::RegionObserver::onNodeCreate ( Node *  node )

pure virtual

Called right after a node is added to the region, after the node has its inputs and output added.

Parameters

node	the node being added

Implemented in jlm::rvsdg::detail::ForwardingObserver< Traverser >, jlm::rvsdg::detail::ForwardingObserver< BottomUpTraverserGeneric >, jlm::rvsdg::detail::ForwardingObserver< TopDownTraverserGeneric >, and jlm::rvsdg::RecordingObserver.

onNodeDestroy()

virtual void jlm::rvsdg::RegionObserver::onNodeDestroy ( Node *  node )

pure virtual

Called right before a node is removed from the region, before the node has its inputs and outputs removed.

Parameters

node	the node being removed

Implemented in jlm::rvsdg::detail::ForwardingObserver< Traverser >, jlm::rvsdg::detail::ForwardingObserver< BottomUpTraverserGeneric >, jlm::rvsdg::detail::ForwardingObserver< TopDownTraverserGeneric >, and jlm::rvsdg::RecordingObserver.
