SpatialDataType

A spatial data type. This class supports up to 31 dimensions. Each dimension can have a minimum and a maximum value of type float. For each dimension, the maximum value is only stored when it is not the same as the minimum.

Methods
int	compare(Object a, Object b)
int	compare(Object a, Object b)
boolean	contains(Object objA, Object objB) Check whether a contains b.
boolean	contains(Object objA, Object objB) Check whether a contains b. Parameters: objA - the bounding box objB - the object Returns: the area
Object	createBoundingBox(Object objA) Create a bounding box starting with the given object.
Object	createBoundingBox(Object objA) Create a bounding box starting with the given object. Parameters: objA - the object Returns: the bounding box
boolean	equals(Object a, Object b) Check whether two spatial values are equal.
boolean	equals(Object a, Object b) Check whether two spatial values are equal. Parameters: a - the first value b - the second value Returns: true if they are equal
float	getAreaIncrease(Object objA, Object objB) Get the area increase by extending a to contain b.
float	getAreaIncrease(Object objA, Object objB) Get the area increase by extending a to contain b. Parameters: objA - the bounding box objB - the object Returns: the area
float	getCombinedArea(Object objA, Object objB) Get the combined area of both objects.
float	getCombinedArea(Object objA, Object objB) Get the combined area of both objects. Parameters: objA - the first object objB - the second object Returns: the area
int[]	getExtremes(ArrayList list) Get the most extreme pair (elements that are as far apart as possible).
int[]	getExtremes(ArrayList list) Get the most extreme pair (elements that are as far apart as possible). This method is used to split a page (linear split). If no extreme objects could be found, this method returns null. Parameters: list - the objects Returns: the indexes of the extremes
int	getMemory(Object obj)
int	getMemory(Object obj)
void	increaseBounds(Object bounds, Object add) Increase the bounds in the given spatial object.
void	increaseBounds(Object bounds, Object add) Increase the bounds in the given spatial object. Parameters: bounds - the bounds (may be modified) add - the value
boolean	isInside(Object objA, Object objB) Check whether a is completely inside b and does not touch the given bound.
boolean	isInside(Object objA, Object objB) Check whether a is completely inside b and does not touch the given bound. Parameters: objA - the object to check objB - the bounds Returns: true if a is completely inside b
boolean	isOverlap(Object objA, Object objB) Check whether the two objects overlap.
boolean	isOverlap(Object objA, Object objB) Check whether the two objects overlap. Parameters: objA - the first object objB - the second object Returns: true if they overlap
void	read(ByteBuffer buff, Object[] obj, int len, boolean key)
void	read(ByteBuffer buff, Object[] obj, int len, boolean key)
Object	read(ByteBuffer buff)
Object	read(ByteBuffer buff)
void	write(WriteBuffer buff, Object[] obj, int len, boolean key)
void	write(WriteBuffer buff, Object[] obj, int len, boolean key)
void	write(WriteBuffer buff, Object obj)
void	write(WriteBuffer buff, Object obj)
