Field Details

INTERACT
static final int INTERACTTopology relation constant INTERACT Two
ILcdShape
objects INTERACT if and only if there is some overlap meaning they have at least one point in common. See Also:

CONTAIN
static final int CONTAINConstant to be used to indicate the operation to be performed is to check whether the first shape contains the second shape. This is the inverse of the
INSIDE
operation.This is a more finegrained check than the
INTERACT
check. If this check returnstrue
, theINTERACT
check will also return true. See Also:

INSIDE
static final int INSIDEConstant to be used to indicate the operation to be performed is to check whether the first shape is inside the second shape. This is the inverse of the
CONTAIN
operation.This is a more finegrained check than the
INTERACT
check. If this check returnstrue
, theINTERACT
check will also return true. See Also:

LINE_INTERSECT
static final int LINE_INTERSECTConstant to be used to indicate the operation to be performed is to check whether the first shape boundary intersects the second shape boundary.
This is a more finegrained check than the
INTERACT
check. If this check returnstrue
, theINTERACT
check will also return true. See Also:
