Method Detail

getSize

int getSize()

Returns:

the number of Geometry within the aggregation

merge

void merge(Aggregate aggregate)
           throws GeometryException

merges two aggregation.

Parameters:

aggregate -

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

Parameters:

gmo - 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

Parameters:

gmo - to remove

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.

Parameters:

index -

Returns:

the removed Geometry

Throws:

GeometryException

removeAll

void removeAll()

removes all Geometry from the aggregation.

getObjectAt

Geometry getObjectAt(int index)

Parameters:

index - to get

Returns:

the Geometry at the submitted index.

getAll

Geometry[] getAll()

Returns:

all Geometries as array

isMember

boolean isMember(Geometry gmo)

Parameters:

gmo -

Returns:

true if the submitted Geometry is within the aggregation

getIterator

Iterator<Geometry> getIterator()

Returns:

the aggregation as an iterator
