public interface ILcdRemoteOWSModelDecoder

Decoder for user-defined layers.

Method Summary

Modifier and Type	Method and Description
boolean	canDecode(TLcdSLDUserLayer aUserLayer, TLcdWMSRequestContext aWMSRequestContext) Checks whether this ILcdRemoteOWSModelDecoder can decode the supplied user-defined layer.
ILcdModel[]	decode(TLcdSLDUserLayer aUserLayer, TLcdWMSRequestContext aWMSRequestContext) Returns the ILcdModel(s) corresponding to a user-defined layer.

Method Detail

canDecode

boolean canDecode(TLcdSLDUserLayer aUserLayer,
                  TLcdWMSRequestContext aWMSRequestContext)

Checks whether this ILcdRemoteOWSModelDecoder can decode the supplied user-defined layer.

Parameters:

aUserLayer - the user-defined layer.

aWMSRequestContext - the WMS request context, which gives access to the original HttpServletRequest that was sent to the WMS and several other parameters.

Returns:

true if this ILcdRemoteOWSModelDecoder can decode the supplied user-defined layer.

decode

ILcdModel[] decode(TLcdSLDUserLayer aUserLayer,
                   TLcdWMSRequestContext aWMSRequestContext)
            throws IOException

Returns the ILcdModel(s) corresponding to a user-defined layer. Whether to return one or more ILcdModel objects depends on the contents of the user-defined layer. If this layer combines multiple coverages (WCS) or feature types (WFS), it may be necessary to decode each coverage or feature type into a single ILcdModel. This is especially needed when these coverages or feature types have multiple model references, because an ILcdModel can be associated with only one model reference.

Parameters:

aUserLayer - the user-defined layer.

aWMSRequestContext - the WMS request context, which gives access to the original HttpServletRequest that was sent to the WMS and several other parameters.

Returns:

the ILcdModel(s) corresponding to the user-defined layer.

Throws:

IOException - if the model can not be returned (because decoding fails).
