Constructor Detail

GeodeTableScan

GeodeTableScan(RelOptCluster cluster,
               RelTraitSet traitSet,
               RelOptTable table,
               GeodeTable geodeTable,
               RelDataType projectRowType)

Creates a GeodeTableScan.

Parameters:

cluster - Cluster

traitSet - Traits

table - Table

geodeTable - Geode table

projectRowType - Fields and types to project; null to project raw row

Method Detail

copy

public RelNode copy(RelTraitSet traitSet,
                    java.util.List<RelNode> inputs)

Description copied from interface: RelNode

Creates a copy of this relational expression, perhaps changing traits and inputs.

Sub-classes with other important attributes are encouraged to create variants of this method with more parameters.

Specified by:

copy in interface RelNode

Overrides:

copy in class AbstractRelNode

Parameters:

traitSet - Trait set

inputs - Inputs

Returns:

Copy of this relational expression, substituting traits and inputs

deriveRowType

public RelDataType deriveRowType()

Overrides:

deriveRowType in class TableScan

register

public void register(RelOptPlanner planner)

Description copied from interface: RelNode

Registers any special rules specific to this kind of relational expression.

The planner calls this method this first time that it sees a relational expression of this class. The derived class should call RelOptPlanner.addRule(org.apache.calcite.plan.RelOptRule) for each rule, and then call super.register.

Specified by:

register in interface RelNode

Overrides:

register in class AbstractRelNode

Parameters:

planner - Planner to be used to register additional relational expressions

implement

public void implement(GeodeRel.GeodeImplementContext geodeImplementContext)

Description copied from interface: GeodeRel

Callback for the implementation process that collects the context from the GeodeRel required to convert the relational tree into physical such.

Specified by:

implement in interface GeodeRel

Parameters:

geodeImplementContext - Context class that collects the feedback from the call back method calls
