Package com.luciad.reference.format

Class TLcdWKTModelReferenceDecoder

java.lang.Object

com.luciad.reference.format.TLcdWKTModelReferenceDecoder

All Implemented Interfaces:

ILcdInputStreamFactoryCapable, ILcdModelReferenceDecoder

@LcdService(service=ILcdModelReferenceDecoder.class,
            priority=20000)
public class TLcdWKTModelReferenceDecoder
extends Object
implements ILcdModelReferenceDecoder, ILcdInputStreamFactoryCapable

This decoder attempts to create a ILcdModelReference from a file in the directory of the given data source file aSource.

• If the file name aSource is <name>.xxx, it first tries to open a file called <name>.prj.
• If this file does not exist, it tries to open a file called directory.prj (this can be used as a common default file for all the data files in the same directory).
• It this file does not exist, a IOException is thrown..

The extension .prj and .PRJ is tried for case sensitive file systems.

Method Details

decodeModelReference

public ILcdModelReference decodeModelReference(String aDataSourceName)
                                        throws IOException

Returns the model reference, associated with the specified data source. This implementation delegates to findAndDecodeModelReference(java.lang.String) and returns the resulting model reference.

Specified by:

decodeModelReference in interface ILcdModelReferenceDecoder

Parameters:

aDataSourceName - a data source for which to return the model reference; typically a file name or a URL.

Returns:

the ILcdModelReference associated with the data source. While null is allowed, implementors are advised to throw an error instead.

Throws:

IOException - if the ILcdModelReference cannot be decoded.
When the thread on which this method is called is interrupted, it is recommended to stop the decoding and throw an InterruptedIOException. This same exception can also be used if the decoder shows UI to the user, and the user cancels the decoding through the UI.

findAndDecodeModelReference

public ILcdModelReferenceDecoder.ModelReferenceWithSource findAndDecodeModelReference(String aSource)
                                                                               throws IOException

Description copied from interface: ILcdModelReferenceDecoder

Finds and decodes the model reference file, associated with the specified data source. The default implementation delegates to ILcdModelReferenceDecoder.decodeModelReference(java.lang.String) and returns the resulting model reference, paired with a null source, indicating that the source is unknown or does not exist.

Specified by:

findAndDecodeModelReference in interface ILcdModelReferenceDecoder

Parameters:

aSource - a data source for which to return the model reference; typically a file name or a URL.

Returns:

the decoded ILcdModelReference and the location of the reference file. Never null.

Throws:

IOException - if no model reference file is found, or the ILcdModelReference cannot be decoded.
When the thread on which this method is called is interrupted, it is recommended to stop the decoding and throw an InterruptedIOException. This same exception can also be used if the decoder shows UI to the user, and the user cancels the decoding through the UI.

setInputStreamFactory

public void setInputStreamFactory(ILcdInputStreamFactory aInputStreamFactory)

Description copied from interface: ILcdInputStreamFactoryCapable

Sets the input stream factory to be used.

Specified by:

setInputStreamFactory in interface ILcdInputStreamFactoryCapable

Parameters:

aInputStreamFactory - the input stream factory to be used.

getInputStreamFactory

public ILcdInputStreamFactory getInputStreamFactory()

Description copied from interface: ILcdInputStreamFactoryCapable

Returns the input stream factory that is used.

Specified by:

getInputStreamFactory in interface ILcdInputStreamFactoryCapable

Returns:

the input stream factory that is used.
