Create a descriptor from another, but change the relative index

Parameters:

relativeIndex - new relative index

that - other image descriptor

AddeImageDescriptor

public AddeImageDescriptor(AddeImageDescriptor that)

Create a descriptor from another.

Parameters:

that - other image descriptor

AddeImageDescriptor

public AddeImageDescriptor(java.lang.String imageSource)

Create an image descriptor from the source

Parameters:

imageSource - ADDE URL

AddeImageDescriptor

public AddeImageDescriptor(edu.wisc.ssec.mcidas.AreaDirectory directory,
                           java.lang.String imageSource)

Create an image descriptor from the source and AreaDirectory

Parameters:

directory - image metadata

imageSource - ADDE URL of image

AddeImageDescriptor

public AddeImageDescriptor(edu.wisc.ssec.mcidas.AreaDirectory directory,
                           java.lang.String imageSource,
                           AddeImageInfo info)

Create an image descriptor from the source and AreaDirectory

Parameters:

directory - image metadata

imageSource - ADDE URL of image

info - Image info

Method Detail

isFromFile

protected boolean isFromFile()

Does this represent a file

Returns:

Is it a file

processSourceAsAddeUrl

protected edu.wisc.ssec.mcidas.AreaDirectory processSourceAsAddeUrl(java.lang.String imageSource)

Create an AreaDirectory from the ADDE URL. If the URL is a data request (imagedata) then munge it to make an imagedir request.

Parameters:

imageSource - ADDE URL

Returns:

corresponding image metadata

createElement

public org.w3c.dom.Element createElement(XmlEncoder encoder)

We just have this here so we can define a XmlDelegate for the AreaDirectory class

Specified by:

createElement in interface XmlPersistable

Parameters:

encoder - encoder to use

Returns:

encoded version of this

createObject

public java.lang.Object createObject(XmlEncoder encoder,
                                     org.w3c.dom.Element element)

Specified by:

createObject in interface XmlDelegate

Parameters:

encoder - encoder to use

element - XML description of this object

Returns:

image description based on the element

initFromXml

public boolean initFromXml(XmlEncoder encoder,
                           org.w3c.dom.Element element)
