Method Detail

setInfinity

public void setInfinity(int infinitude)

Description copied from class: SargEndpoint

Sets this endpoint to either negative or positive infinity. An infinite endpoint implies an open bound (negative infinity implies a lower bound, while positive infinity implies an upper bound).

Overrides:

setInfinity in class SargEndpoint

Parameters:

infinitude - either -1 or +1

setFinite

public void setFinite(SargBoundType boundType,
                      SargStrictness strictness,
                      RexNode coordinate)

Description copied from class: SargEndpoint

Sets a finite value for this endpoint.

Overrides:

setFinite in class SargEndpoint

Parameters:

boundType - bound type (upper/lower)

strictness - boundary strictness

coordinate - endpoint position
