Interface Aggregate

All Superinterfaces:

Geometry, Serializable

All Known Subinterfaces:

MultiCurve, MultiPoint, MultiPrimitive, MultiSolid, MultiSurface

All Known Implementing Classes:

AggregateImpl, MultiCurveImpl, MultiPointImpl, MultiPrimitiveImpl, MultiSurfaceImpl

public interface Aggregate
extends Geometry

This interface defines the basis functionallity of all geometry aggregations. it will be specialized for the use of primitive, and solid geometries.

Method Summary

void	add(Geometry gmo) adds an Geometry to the aggregation
Geometry[]	getAll() returns all Geometries as array
Iterator	getIterator() returns the aggregation as an iterator
Geometry	getObjectAt(int index) returns the Geometry at the submitted index.
int	getSize() returns the number of Geometry within the aggregation
void	insertObjectAt(Geometry gmo, int index) inserts a Geometry in the aggregation. all elements with an index equal or larger index will be moved. if index is larger then getSize() - 1 an exception will be thrown.
boolean	isMember(Geometry gmo) returns true if the submitted Geometry is within the aggregation
void	merge(Aggregate aggregate) merges two aggregation.
void	removeAll() removes all Geometry from the aggregation.
Geometry	removeObject(Geometry gmo) removes the submitted Geometry from the aggregation
Geometry	removeObjectAt(int index) removes the Geometry at the submitted index from the aggregation.
void	setObjectAt(Geometry gmo, int index) sets the submitted Geometry at the submitted index. the element at the position index will be removed. if index is larger then getSize() - 1 an exception will be thrown.

Method Detail

getSize

int getSize()

returns the number of Geometry within the aggregation

merge

void merge(Aggregate aggregate)
           throws GeometryException

merges two aggregation.

Throws:

GeometryException - a GeometryException will be thrown if the submitted isn't the same type as the recieving one.

add

void add(Geometry gmo)

adds an Geometry to the aggregation

insertObjectAt

void insertObjectAt(Geometry gmo,
                    int index)
                    throws GeometryException

inserts a Geometry in the aggregation. all elements with an index equal or larger index will be moved. if index is larger then getSize() - 1 an exception will be thrown.

Parameters:

gmo - Geometry to insert.

index - position where to insert the new Geometry

Throws:

GeometryException

setObjectAt

void setObjectAt(Geometry gmo,
                 int index)
                 throws GeometryException

sets the submitted Geometry at the submitted index. the element at the position index will be removed. if index is larger then getSize() - 1 an exception will be thrown.

Parameters:

gmo - Geometry to set.

index - position where to set the new Geometry

Throws:

GeometryException

removeObject

Geometry removeObject(Geometry gmo)

removes the submitted Geometry from the aggregation

Returns:

the removed Geometry

removeObjectAt

Geometry removeObjectAt(int index)
                        throws GeometryException

removes the Geometry at the submitted index from the aggregation. if index is larger then getSize() - 1 an exception will be thrown.

Returns:

the removed Geometry

Throws:

GeometryException

removeAll

void removeAll()

removes all Geometry from the aggregation.

getObjectAt

Geometry getObjectAt(int index)

returns the Geometry at the submitted index.

getAll

Geometry[] getAll()

returns all Geometries as array

isMember

boolean isMember(Geometry gmo)

returns true if the submitted Geometry is within the aggregation

getIterator

Iterator getIterator()

returns the aggregation as an iterator
