getSubTuple

public LeftTuple getSubTuple(int elements)

Description copied from interface: Tuple

Returns the ReteTuple that contains the "elements" first elements in this tuple.

Use carefully as no cloning is made during this process.

This method is used by TupleStartEqualsConstraint when joining a subnetwork tuple into the main network tuple;

Parameters:

elements - the number of elements to return, starting from the begining of the tuple

Returns:

a ReteTuple containing the "elements" first elements of this tuple or null if "elements" is greater than size;
