Method Detail

getSize

public int getSize()

Specified by:

getSize in interface Aggregate

Returns:

the number of Geometry within the aggregation

merge

public void merge(Aggregate aggregate)
           throws GeometryException

merges this aggregation with another one

Specified by:

merge in interface Aggregate

Throws:

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

add

public void add(Geometry gmo)

adds an Geometry to the aggregation

Specified by:

add in interface Aggregate

Parameters:

gmo - Geometry to the aggregation

insertObjectAt

public 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 or smaller then 0 or gmo equals null an exception will be thrown.

Specified by:

insertObjectAt in interface Aggregate

Parameters:

gmo - Geometry to insert.

index - position where to insert the new Geometry

Throws:

GeometryException

setObjectAt

public 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 or smaller then 0 or gmo equals null an exception will be thrown.

Specified by:

setObjectAt in interface Aggregate

Parameters:

gmo - Geometry to set.

index - position where to set the new Geometry

Throws:

GeometryException

removeObject

public Geometry removeObject(Geometry gmo)

removes the submitted Geometry from the aggregation

Specified by:

removeObject in interface Aggregate

Parameters:

gmo - to remove

Returns:

the removed Geometry

removeObjectAt

public Geometry removeObjectAt(int index)
                        throws GeometryException

removes the Geometry at the submitted index from the aggregation. if index is larger then getSize() - 1 or smaller then 0 an exception will be thrown.

Specified by:

removeObjectAt in interface Aggregate

Returns:

the removed Geometry

Throws:

GeometryException

removeAll

public void removeAll()

removes all Geometry from the aggregation.

Specified by:

removeAll in interface Aggregate

getObjectAt

public Geometry getObjectAt(int index)

returns the Geometry at the submitted index. if index is larger then getSize() - 1 or smaller then 0 an exception will be thrown.

Specified by:

getObjectAt in interface Aggregate

Parameters:

index - to get

Returns:

the Geometry at the submitted index.

getAll

public Geometry[] getAll()

returns all Geometries as array

Specified by:

getAll in interface Aggregate

Returns:

all Geometries as array

isMember

public boolean isMember(Geometry gmo)

Specified by:

isMember in interface Aggregate

Returns:

true if the submitted Geometry is within the aggregation

getIterator

public Iterator<Geometry> getIterator()

Specified by:

getIterator in interface Aggregate

Returns:

the aggregation as an iterator

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Geometry

Overrides:

isEmpty in class GeometryImpl

Returns:

true if no geometry values resp. points stored within the geometry.

setCoordinateSystem

public void setCoordinateSystem(CoordinateSystem crs)

Description copied from class: GeometryImpl

sets the spatial reference system

Overrides:

setCoordinateSystem in class GeometryImpl

Parameters:

crs - new spatial reference system
