Method Detail

getScaleHint

public ScaleHint getScaleHint()

returns the scale interval the data source is valid

getName

public java.lang.String getName()

returns the name of the data source. The method may returns null if so no name is defined and a online resource or WFS filter have shall be returned.

getType

public int getType()

returns the type of the data source. possible values are:

• LOCALWFS
• LOCALWCS
• REMOTEWFS
• REMOTEWCS
• REMOTEWMS

the values are defined as constants in DataSource

Returns:

getOGCWebService

public OGCWebService getOGCWebService()

returns an instance of the OGCWebService that represents the datasource. Notice: if more than one layer uses data that are offered by the same OWS the deegree WMS shall just use one instance for accessing the OWS

getQuery

public WFSQuery getQuery()

returns the WFS Query describe the access/filtering to the data source.

getGetMapRequest

public WMSGetMapRequest getGetMapRequest()

returns an instance of a WMSGetMapRequest encapsulating the filter conditions against a remote WMS. The request object contains: WMTVER, LAYERS, STYLES, FORMAT, TRANSPARENT, VENDORSPECIFICPARAMETERS

Returns:

filter conditions

getGetCoverageRequest

public WCSGetCoverageRequest getGetCoverageRequest()

returns an instance of a WCSGetCoverageRequest encapsulating the filter conditions against a remote WCS. The request object contains: VERSION, LAYER, FORMAT, VENDORSPECIFICPARAMETERS

Returns:

filter conditions

getGeometryProperty

public java.lang.String getGeometryProperty()

Returns the name of the geometry property in case the datasource is of type LOCALWFS / REMOTEWFS.

Returns:

name of the geometry property
