/**
|
59 |
* Implements an abstract class for the different kinds of layer that supports SLD
|
60 |
* implementation specification .<p>
|
61 |
* The Name element identifies the well-known name of the layer being referenced, and is
|
62 |
* required. All possible well-known names are usually identified in the capabilities
|
63 |
* document for a server.<p>
|
64 |
* The LayerFeatureConstraints element is optional in a NamedLayer and allows the
|
65 |
* user to specify constraints on what features of what feature types are to be
|
66 |
* selected by the named-layer reference. It is essentially a filter that allows the
|
67 |
* selection of fewer features than are present in the named layer.<p>
|
68 |
* A named styled layer can include any number of named styles and user-defined
|
69 |
* styles,including zero, mixed in any order. If zero styles are specified, then
|
70 |
* the default styling for the specified named layer is to be used.<p>
|
71 |
* A named style, similar to a named layer, is referenced by a well-known name. A
|
72 |
* particular named style only has meaning when used in conjunction with a particular
|
73 |
* named layer. All available styles for each available layer are normally named in a
|
74 |
* capabilities document.
