CrossProjection

public CrossProjection(DataSet<I1> ds1,
                       DataSet<I2> ds2,
                       int[] firstFieldIndexes,

Method Detail

projectFirst

protected CrossOperator.CrossProjection<I1,I2> projectFirst(int... firstFieldIndexes)

Continues a ProjectCross transformation and adds fields of the first cross input.

If the first cross input is a Tuple DataSet, fields can be selected by their index. If the first cross input is not a Tuple DataSet, no parameters should be passed.

Fields of the first and second input can be added by chaining the method calls of projectFirst(int...) and projectSecond(int...).

Parameters:

firstFieldIndexes - If the first input is a Tuple DataSet, the indexes of the selected fields. For a non-Tuple DataSet, do not provide parameters. The order of fields in the output tuple is defined by to the order of field indexes.

Returns:

An extended CrossProjection.

Tuple, DataSet, CrossOperator.CrossProjection, CrossOperator.ProjectCross

projectSecond

protected CrossOperator.CrossProjection<I1,I2> projectSecond(int... secondFieldIndexes)

Continues a ProjectCross transformation and adds fields of the second cross input.

If the second cross input is a Tuple DataSet, fields can be selected by their index. If the second cross input is not a Tuple DataSet, no parameters should be passed.

Fields of the first and second input can be added by chaining the method calls of projectFirst(int...) and projectSecond(int...).

Parameters:

secondFieldIndexes - If the second input is a Tuple DataSet, the indexes of the selected fields. For a non-Tuple DataSet, do not provide parameters. The order of fields in the output tuple is defined by to the order of field indexes.

Returns:

An extended CrossProjection.
