Field Detail aggInfo AggregatorInfo aggInfo(Code) aggregatorColumnId int aggregatorColumnId(Code) Constructor Detail GenericAggregator GenericAggregator(AggregatorInfo aggInfo, ClassFactory cf)(Code) Constructor: Parameters:   aggInfo - information about the user aggregate Parameters:   cf - the class factory. Method Detail accumulate void accumulate(ExecRow inputRow, ExecRow accumulateRow) throws StandardException(Code) Accumulate the aggregate results. This is the guts of the aggregation. We will call the user aggregate on itself to do the aggregation. Parameters:   inputRow - the row with the input colum Parameters:   accumulateRow - the row with the aggregator exception:   StandardException - on error accumulate void accumulate(Object[] inputRow, Object[] accumulateRow) throws StandardException(Code) Accumulate the aggregate results. This is the guts of the aggregation. We will call the user aggregate on itself to do the aggregation. Parameters:   inputRow - the row with the input colum Parameters:   accumulateRow - the row with the aggregator exception:   StandardException - on error accumulate void accumulate(DataValueDescriptor inputColumn, DataValueDescriptor aggregatorColumn) throws StandardException(Code) Accumulate the aggregate results. This is the guts of the aggregation. We will call the user aggregate on itself to do the aggregation. Parameters:   inputColumn - Parameters:   aggregatorColumn - exception:   StandardException - on error finish boolean finish(ExecRow row) throws StandardException(Code) Get the results of the aggregation and put it in the result column. Parameters:   row - the row with the result and the aggregator exception:   StandardException - on error getAggregatorInfo AggregatorInfo getAggregatorInfo()(Code) getAggregatorInstance ExecAggregator getAggregatorInstance() throws StandardException(Code) Get a new instance of the aggregator and initialize it. an exec aggregator exception:   StandardException - on error getColumnId int getColumnId()(Code) Return the column id that is being aggregated initialize void initialize(ExecRow row) throws StandardException(Code) Initialize the aggregator Parameters:   row - the row with the aggregator to be initialized exception:   StandardException - on error merge void merge(ExecRow inputRow, ExecRow mergeRow) throws StandardException(Code) Merge the aggregate results. This is the guts of the aggregation. We will call the user aggregate on itself to do the aggregation. Parameters:   inputRow - the row with the input colum Parameters:   mergeRow - the row with the aggregator exception:   StandardException - on error merge void merge(Object[] inputRow, Object[] mergeRow) throws StandardException(Code) Merge the aggregate results. This is the guts of the aggregation. We will call the user aggregate on itself to do the aggregation. Parameters:   inputRow - the row with the input colum Parameters:   mergeRow - the row with the aggregator exception:   StandardException - on error merge void merge(Storable aggregatorColumnIn, Storable aggregatorColumnOut) throws StandardException(Code) Merge two partial aggregations. This is how the sorter merges partial aggregates. exception:   StandardException - on error Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
