Class RelativePosition

java.lang.Object

org.brains2b.struct.position.RelativePosition

All Implemented Interfaces:

Position

Direct Known Subclasses:

AfterPosition, BeforePosition, WithinPosition

public abstract class RelativePosition
extends java.lang.Object
implements Position

RelativePostion returns the Position of a Position object before an anchor given the supplied conditions

The conditions which can be supplied are:

• size of gap (number of separable tokens) where 0 is irrelevant
• absolute gap measure meaning the word should be exactly the number of gaps removed from the anchor. If gap = 1 this will always be absolute
• not-indicator meaning the start should not be found around the anchor
