Methods in org.apache.calcite.adapter.pig with parameters of type PigRel.Implementor

Modifier and Type	Method and Description
private String	PigTableScan.getConcatenatedFieldNameAndTypeForPigSchema(PigRel.Implementor implementor, RelDataTypeField field)
private List<String>	PigAggregate.getDistinctCalls(PigRel.Implementor implementor) A agg function call like COUNT(DISTINCT COL) in Pig is achieved via two statements in a FOREACH that follows a GROUP statement: TABLE = GROUP TABLE ALL; TABLE = FOREACH TABLE { COL.DISTINCT = DISTINCT COL; GENERATE COUNT(COL.DISTINCT) AS C; }
private List<String>	PigAggregate.getPigAggregateCalls(PigRel.Implementor implementor)
private String	PigAggregate.getPigAggregateStatement(PigRel.Implementor implementor) Generates a GROUP BY statement, followed by an optional FOREACH statement for all aggregate functions used.
private String	PigFilter.getPigFilterStatement(PigRel.Implementor implementor) Generates Pig Latin filtering statements, for example
private String	PigAggregate.getPigForEachGenerate(PigRel.Implementor implementor) Generates a FOREACH statement containing invocation of aggregate functions and projection of grouped fields.
private String	PigAggregate.getPigGenerateCall(PigRel.Implementor implementor)
private String	PigAggregate.getPigGroupBy(PigRel.Implementor implementor) Generates the GROUP BY statement, e.g.
private String	PigJoin.getPigJoinStatement(PigRel.Implementor implementor) Constructs a Pig JOIN statement in the form of
private String	PigTableScan.getSchemaForPigStatement(PigRel.Implementor implementor)
private String	PigFilter.getSingleFilterCondition(PigRel.Implementor implementor, RexNode node)
private String	PigFilter.getSingleFilterCondition(PigRel.Implementor implementor, String op, RexCall call)
