Constructor Detail

DefaultExtension

public DefaultExtension(String type)
                 throws UnknownCVExtensionException

constructor initializing an empty Extension

Parameters:

type -

Throws:

UnknownCVExtensionException

DefaultExtension

public DefaultExtension(String type,
                        Resolution[] resolutions,
                        double offset,
                        double scaleFactor)
                 throws UnknownCVExtensionException

initializing the Extension with the passed Resolutions

Parameters:

type -

resolutions -

offset -

scaleFactor -

Throws:

UnknownCVExtensionException

Method Detail

getType

public String getType()

returns the type of the coverage source that is described be an extension

Specified by:

getType in interface Extension

Returns:

the type of the coverage source that is described be an extension

setType

public void setType(String type)
             throws UnknownCVExtensionException

returns the type of the coverage source that is described be an extension. Valid types are:

• shapeIndexed
• nameIndexed
• file

This list may be extended in future versions of deegree

Parameters:

type -

Throws:

UnknownCVExtensionException

getMinScale

public double getMinScale()

returns the minimum scale of objects that are described by an Extension object

Specified by:

getMinScale in interface Extension

Returns:

the minimum scale of objects that are described by an Extension object

getOffset

public double getOffset()

returns the offset of the data. 0 will be returned if no offset is defined. Data first must be divided by the scale factor (@see #getScaleFactor()) before sustracting the offset

Specified by:

getOffset in interface Extension

Returns:

getScaleFactor

public double getScaleFactor()

returns the scale factor of the data. If no scale factor is defined 1 will be returned. Data first must be divided by the scale factor (@see #getScaleFactor()) before sustracting the offset

Specified by:

getScaleFactor in interface Extension

Returns:

getMaxScale

public double getMaxScale()

returns the maximum scale of objects that are described by an Extension object

Specified by:

getMaxScale in interface Extension

Returns:

the maximum scale of objects that are described by an Extension object

getResolutions

public Resolution[] getResolutions()

returns all Resolutions . If no Resolution can be found for the passed scale an empty array will be returned.

Specified by:

getResolutions in interface Extension

Parameters:

scale - scale the returned resolutions must fit

Returns:

Resolutions matching the passed scale

getResolutions

public Resolution[] getResolutions(double scale)

returns the Resolutions matching the passed scale. If no Resolution can be found for the passed scale an empty array will be returned.

Specified by:

getResolutions in interface Extension

Parameters:

scale - scale the returned resolutions must fit

Returns:

Resolutions matching the passed scale

addResolution

public void addResolution(Resolution resolution)

Specified by:

addResolution in interface Extension

Parameters:

resolution -
