Interface Envelope

@UML(identifier="GM_Envelope",
     specification=ISO_19107)
public interface Envelope

A minimum bounding box or rectangle. Regardless of dimension, an Envelope can be represented without ambiguity as two direct positions (coordinate points). To encode an Envelope, it is sufficient to encode these two points. This is consistent with all of the data types in this specification, their state is represented by their publicly accessible attributes.

Since:

GeoAPI 1.0

Version:

Abstract specification 5

Method Summary

double	getCenter(int dimension) Returns the center ordinate along the specified dimension.
int	getDimension() The length of coordinate sequence (the number of entries) in this envelope.
double	getLength(int dimension) Returns the envelope length along the specified dimension.
DirectPosition	getLowerCorner() A coordinate position consisting of all the minimal ordinates for each dimension for all points within the Envelope.
double	getMaximum(int dimension) Returns the maximal ordinate along the specified dimension.
double	getMinimum(int dimension) Returns the minimal ordinate along the specified dimension.
DirectPosition	getUpperCorner() A coordinate position consisting of all the maximal ordinates for each dimension for all points within the Envelope.

Method Detail

getDimension

@Extension
int getDimension()

The length of coordinate sequence (the number of entries) in this envelope.

Returns:

The dimensionality of this envelope.

Since:

GeoAPI 2.0

getMinimum

@Extension
double getMinimum(int dimension)

Returns the minimal ordinate along the specified dimension.

Since:

GeoAPI 2.0

getMaximum

@Extension
double getMaximum(int dimension)

Returns the maximal ordinate along the specified dimension.

Since:

GeoAPI 2.0

getCenter

@Extension
double getCenter(int dimension)

Returns the center ordinate along the specified dimension.

Since:

GeoAPI 2.0

getLength

@Extension
double getLength(int dimension)

Returns the envelope length along the specified dimension. This length is equals to the maximum ordinate minus the minimal ordinate.

Since:

GeoAPI 2.0

getUpperCorner

@UML(identifier="upperCorner",
     obligation=MANDATORY,
     specification=ISO_19107)
DirectPosition getUpperCorner()

A coordinate position consisting of all the maximal ordinates for each dimension for all points within the Envelope.

Returns:

The upper corner.

getLowerCorner

@UML(identifier="lowerCorner",
     obligation=MANDATORY,
     specification=ISO_19107)
DirectPosition getLowerCorner()

A coordinate position consisting of all the minimal ordinates for each dimension for all points within the Envelope.

Returns:

The lower corner.
