VectorFilterOperator

public VectorFilterOperator(CompilationOpContext ctx,
                            OperatorDesc conf,
                            VectorizationContext vContext,
                            VectorDesc vectorDesc)
                     throws HiveException

Throws:

HiveException

VectorFilterOperator

public VectorFilterOperator()

Kryo ctor.

VectorFilterOperator

public VectorFilterOperator(CompilationOpContext ctx)

Method Detail

getInputVectorizationContext

public VectorizationContext getInputVectorizationContext()

Specified by:

getInputVectorizationContext in interface VectorizationOperator

initializeOp

protected void initializeOp(org.apache.hadoop.conf.Configuration hconf)
                     throws HiveException

Description copied from class: Operator

Operator specific initialization.

Overrides:

initializeOp in class FilterOperator

Throws:

HiveException

setFilterCondition

public void setFilterCondition(VectorExpression expr)

process

public void process(Object row,
                    int tag)
