Method Details

symRel

public static int symRel(int aRelation)
                  throws IllegalArgumentException

Returns the symmetrical relation of a given binary topology relation. Relations R1 and R2 are considered symmetrical if R1 applied to (aS1, aS2) equals R2 applied to (aS2, aS1). For the given operation:

• symRel(INTERACT) == INTERACT
• symRel(CONTAINS) == INSIDE
• symRel(INSIDE) == CONTAINS
• symRel(LINE_INTERSECTS) == LINE_INTERSECTS

Parameters:

aRelation - binary topology relation.

Returns:

the symmetrical binary topology relation.

Throws:

IllegalArgumentException - if the symmetrical relation is not known.
