Returns:

code indicating reason execution ceased

Implements ExecStream.

Checks the state of the input and output buffers.

If input empty, requests production. If input EOS, propagates that to output buffer. If output full, returns EXECRC_OVERFLOW.

Returns:

result of precheck; anything but EXECRC_YIELD indicates that execution should terminate immediately with returned code

Prepares this stream for execution.

A precondition is that input streams must already be defined and prepared. As an effect of this call, the tuple shape should be defined for all output buffers and remain unchanged for the lifetime of the stream. This method is only ever called once, before the first open. Although this method is virtual, derived classes may choose to define an overloaded version instead with a specialized covariant parameter class.

Parameters:

Determines resource requirements for this stream.

Default implementation declares zero resource requirements.

Parameters:

Reimplemented in MockResourceExecStream, BTreePrefetchSearchExecStream, LhxAggExecStream, LhxJoinExecStream, LbmGeneratorExecStream, LbmUnionExecStream, and ExternalSortExecStreamImpl.

Sets current resource allocation for this stream.

If called while the stream is open, this indicates a request for the stream to dynamically adjust its memory usage. If the stream is incapable of honoring the request, it should update quantity with the actual amounts still in use.

Parameters:

Reimplemented in MockResourceExecStream, BTreePrefetchSearchExecStream, LhxAggExecStream, LhxJoinExecStream, LbmGeneratorExecStream, LbmUnionExecStream, and ExternalSortExecStreamImpl.

| bool ExecStream::mayBlock | ( | | ) | const [virtual, inherited] | | ------------------------- | - | | - | ---------------------------- |

Queries whether this stream's implementation may block when execute() is called.

For accurate scheduling, non-blocking implementations are preferred; the scheduler must be aware of the potential for blocking so that it can allocate extra threads accordingly.

Returns:

whether stream may block; default is false

Dataflow graph containing this stream.

Note that we don't use a weak_ptr for this because it needs to be accessed frequently during execution, and the extra locking overhead would be frivolous.
