Stalling the sink pipes and exclusive access

void stall (MIDIStaller *cause=eternal_stall)
 Stall this MIDI source. More...
 
void unstall (MIDIStaller *cause=eternal_stall)

Member Function Documentation

◆ stall()

void stall ( MIDIStaller cause = eternal_stall)

Stall this MIDI source.

This means that this becomes the only source that can sink to the sinks connected to this source. Other sources have to wait until this source un-stalls the pipe before they can send again.

Parameters
causePointer to the reason for this stall, can be called back to un-stall the pipes.

Definition at line 157 of file MIDI_Pipes.cpp.

◆ unstall()

void unstall ( MIDIStaller cause = eternal_stall)

Un-stall the pipes connected to this source, so other sources are allowed to send again.

Parameters
causePointer to the reason for the stall (this has to be the same one that was used to stall).

Definition at line 162 of file MIDI_Pipes.cpp.

◆ getStaller()

MIDIStaller * getStaller ( ) const

Get a pointer to whatever is causing this MIDI source to be stalled.

There could be multiple stallers, this function just returns one.

Definition at line 173 of file MIDI_Pipes.cpp.

◆ getStallerName()

const char * getStallerName ( ) const

Get the name of whatever is causing this MIDI source to be stalled.

There could be multiple stallers, this function just returns one.

Definition at line 179 of file MIDI_Pipes.cpp.

◆ disconnect()

bool disconnect ( TrueMIDI_Sink sink)

Disconnect the given sink from this source.

Leaves other sinks connected. Returns true if the sink was found and disconnected, false if the given sink was not a direct or indirect sink of this source.

Definition at line 99 of file MIDI_Pipes.cpp.

◆ stallUpstream()

virtual void stallUpstream ( MIDIStaller ,
MIDI_Sink  
)
inlineprivatevirtual

Base case for recursive stall function.

See also
MIDI_Pipe::stallUpstream

Reimplemented in MIDI_Pipe.

Definition at line 241 of file MIDI_Pipes.hpp.

◆ unstallUpstream()

virtual void unstallUpstream ( MIDIStaller ,
MIDI_Sink  
)
inlineprivatevirtual

Base case for recursive un-stall function.

See also
MIDI_Pipe::unstallUpstream

Reimplemented in MIDI_Pipe.

Definition at line 244 of file MIDI_Pipes.hpp.

◆ getInitialSource()

virtual MIDI_Source* getInitialSource ( )
inlineprivatevirtual

Base case for recursive function.

See also
MIDI_Pipe::getInitialSource

Reimplemented in MIDI_Pipe.

Definition at line 247 of file MIDI_Pipes.hpp.

◆ disconnectSinkPipesShallow()

void disconnectSinkPipesShallow ( )
private

Disconnect only the first pipe connected to this source.

Leaves the other pipes connected to the original pipe, which doesn't have a source anymore when this function finishes. Used to disconnect a MIDI_Pipe while preserving the connections of its “through” outputs.
