public static interface Http2Connection.Listener

Listener for life-cycle events for streams in this connection.

Method Summary

Methods

Modifier and Type	Method and Description
void	goingAway() Called when a GO_AWAY frame has either been sent or received for the connection.
void	onWeightChanged(Http2Stream stream, short oldWeight) Notifies the listener that the weight has changed for stream
void	priorityTreeParentChanged(Http2Stream stream, Http2Stream oldParent) Notifies the listener that a priority tree parent change has occurred.
void	priorityTreeParentChanging(Http2Stream stream, Http2Stream newParent) Notifies the listener that a parent dependency is about to change This is called while the tree is being restructured and so the tree structure is not necessarily steady state.
void	streamActive(Http2Stream stream) Notifies the listener that the given stream was made active (i.e. open in at least one direction).
void	streamAdded(Http2Stream stream) Notifies the listener that the given stream was added to the connection.
void	streamHalfClosed(Http2Stream stream) Notifies the listener that the given stream is now half-closed.
void	streamInactive(Http2Stream stream) Notifies the listener that the given stream is now closed in both directions.
void	streamRemoved(Http2Stream stream) Notifies the listener that the given stream has now been removed from the connection and will no longer be returned via Http2Connection.stream(int).

Method Detail

streamAdded

void streamAdded(Http2Stream stream)

Notifies the listener that the given stream was added to the connection. This stream may not yet be active (i.e. open/half-closed).

streamActive

void streamActive(Http2Stream stream)

Notifies the listener that the given stream was made active (i.e. open in at least one direction).

streamHalfClosed

void streamHalfClosed(Http2Stream stream)

Notifies the listener that the given stream is now half-closed. The stream can be inspected to determine which side is closed.

streamInactive

void streamInactive(Http2Stream stream)

Notifies the listener that the given stream is now closed in both directions.

streamRemoved

void streamRemoved(Http2Stream stream)

Notifies the listener that the given stream has now been removed from the connection and will no longer be returned via Http2Connection.stream(int). The connection may maintain inactive streams for some time before removing them.

priorityTreeParentChanged

void priorityTreeParentChanged(Http2Stream stream,
                             Http2Stream oldParent)

Notifies the listener that a priority tree parent change has occurred. This method will be invoked in a top down order relative to the priority tree. This method will also be invoked after all tree structure changes have been made and the tree is in steady state relative to the priority change which caused the tree structure to change.

Parameters:

stream - The stream which had a parent change (new parent and children will be steady state)

oldParent - The old parent which stream used to be a child of (may be null)

priorityTreeParentChanging

void priorityTreeParentChanging(Http2Stream stream,
                              Http2Stream newParent)

Notifies the listener that a parent dependency is about to change This is called while the tree is being restructured and so the tree structure is not necessarily steady state.

Parameters:

stream - The stream which the parent is about to change to newParent

newParent - The stream which will be the parent of stream

onWeightChanged

void onWeightChanged(Http2Stream stream,
                   short oldWeight)

Notifies the listener that the weight has changed for stream

Parameters:

stream - The stream which the weight has changed

oldWeight - The old weight for stream

goingAway

void goingAway()

Called when a GO_AWAY frame has either been sent or received for the connection.
