Method Detail

getName

public java.lang.String getName()

The Name element identifies the well-known name of the layer being referenced, and is required. All possible well-known names are usually identified in the capabilities document for a server.

Returns:

the name of the layer

setName

public void setName(java.lang.String name)

sets the

Parameters:

name - the name of the layer

getLayerFeatureConstraints

public LayerFeatureConstraints getLayerFeatureConstraints()

The LayerFeatureConstraints element is optional in a NamedLayer and allows the user to specify constraints on what features of what feature types are to be selected by the named-layer reference. It is essentially a filter that allows the selection of fewer features than are present in the named layer.

Returns:

the LayerFeatureConstraints

setLayerFeatureConstraints

public void setLayerFeatureConstraints(LayerFeatureConstraints layerFeatureConstraints)

Sets the LayerFeatureConstraints for the Layer.

Parameters:

layerFeatureConstraints - the LayerFeatureConstraints

getStyles

public Style[] getStyles()

Returns the styles associated to the Layer. This may be UserStyles or NamedStyles

A UserStyle is at the same semantic level as a NamedStyle used in the context of a WMS. In a sense, a named style can be thought of as a reference to a hidden UserStyle that is stored inside of a map server.

Returns:

the styles of the layer als ArrayList

setStyles

public void setStyles(Style[] styles)

Adds styles to the Layer.

Parameters:

styles - the styles for the layer as Array

addStyle

public void addStyle(Style style)

Adds a style to the Layer.

Parameters:

style - a style to add

removeStyle

public void removeStyle(Style style)

Removes a style from the Layer.

Parameters:

style - a style to remove
