Execution¶

Run a compiled graph inside an execution context, supply runtime components defined in Python, and access live state from a running graph.

`libtcspc.ExecutionContext`	An execution context for a compiled processing graph.
`libtcspc.EndOfProcessing`	Exception raised when processing finished without error, but for a reason other than reaching the end of the input.
`libtcspc.SourceHalted`	Exception raised by `BufferAccessor.pump` when the buffer was halted.

Run-time Python components¶

User-supplied Python objects passed to ExecutionContext to handle input to and output from the graph.

`libtcspc.PySink`	Abstract base class for sinks (output handling processors) written in Python.
`libtcspc.PyAcquisitionReader`	Acquisition reader implemented in Python and supplied as an argument upon creation of the execution context.
`libtcspc.PyBucketSource`	Bucket source implemented in Python and supplied as an argument upon creation of the execution context.

Runtime access¶

Accessor objects expose live state from processors in running graphs. Use an AccessTag declared at graph-definition time to look up the corresponding accessor from ExecutionContext. The accessor has a run-time-generated type but implements one of the Accessor protocols.

`libtcspc.Accessor`	Base protocol for run-time accessors.
`libtcspc.AcquireAccessor`	Run-time accessor for an `Acquire` processor.
`libtcspc.BufferAccessor`	Run-time accessor for a `Buffer` or `RealTimeBuffer` processor.
`libtcspc.CountAccessor`	Run-time accessor for a `Count` processor.
`libtcspc.RecordAbstimeRangeAccessor`	Run-time accessor for a `RecordAbstimeRange` processor.
`libtcspc.RecordLastAccessor`	Run-time accessor for a `RecordLast` processor.
`libtcspc.UniqueBinMapperAccessor`	Run-time accessor for a `UniqueBinMapper` bin mapper.
