Method Detail

translateToPlanInternal

protected Transformation<RowData> translateToPlanInternal(org.apache.flink.table.planner.delegation.PlannerBase planner,
                                                          ExecNodeConfig config)

Description copied from class: ExecNodeBase

Internal method, translates this node into a Flink operator.

Specified by:

translateToPlanInternal in class ExecNodeBase<RowData>

Parameters:

planner - The planner.

config - per-ExecNode configuration that contains the merged configuration from various layers which all the nodes implementing this method should use, instead of retrieving configuration from the planner. For more details check ExecNodeConfig.

supportFusionCodegen

public boolean supportFusionCodegen()

Description copied from interface: FusionCodegenExecNode

Whether this ExecNode supports OFCG or not.

Specified by:

supportFusionCodegen in interface FusionCodegenExecNode

Overrides:

supportFusionCodegen in class ExecNodeBase<RowData>

translateToFusionCodegenSpecInternal

protected OpFusionCodegenSpecGenerator translateToFusionCodegenSpecInternal(org.apache.flink.table.planner.delegation.PlannerBase planner,
                                                                            ExecNodeConfig config,
                                                                            org.apache.flink.table.planner.codegen.CodeGeneratorContext parentCtx)

Description copied from class: ExecNodeBase

Internal method, translates this node into a operator codegen spec generator.

Overrides:

translateToFusionCodegenSpecInternal in class ExecNodeBase<RowData>

Parameters:
