Method Details

getOutputType

org.apache.flink.table.types.logical.RowType getOutputType()

Return the output type of current OpFusionCodegenSpecGenerator.

getManagedMemoryFraction

double getManagedMemoryFraction()

Return the managed memory fraction of this OpFusionCodegenSpecGenerator needed during all fusion operators.

getInputFusionContexts

List<OpFusionContext> getInputFusionContexts()

Return the input OpFusionContext of this OpFusionCodegenSpecGenerator.

processProduce

void processProduce(CodeGeneratorContext codegenCtx)
