Member Data Documentation

CompOperator ReshapeExecStreamParams::compOp

Comparison operator.

Set to COMP_NOOP if no comparisons need to be done. Note that NULLs are currently treated like any other value. I.e., COMP_EQ will match NULL values.

boost::shared_array<FixedBuffer> ReshapeExecStreamParams::pCompTupleBuffer

Optional comparison tuple.

Definition at line 86 of file ReshapeExecStream.h.

Referenced by ReshapeExecStream::initCompareData(), ExecStreamTestSuite::testReshapeExecStream(), and ExecStreamFactory::visit().

TupleProjection ReshapeExecStreamParams::inputCompareProj

Optional tuple projection representing the columns to be compared against the comparison tuple and/or dynamic parameters.

The columns being compared against dynamic parameters appear at the end of the projection.

TupleProjection ReshapeExecStreamParams::outputProj

Tuple projection of the output tuple from the input stream.

std::vector<ReshapeParameter> ReshapeExecStreamParams::dynamicParameters

Dynamic parameters used by this stream that are compared to the input row and/or written to the output tuple.
