Examples of org.geotools.data.DataAccessFactory.canProcess()

org.geotools.data.DataAccessFactory.canProcess()
Test to see if this factory is suitable for processing the data pointed to by the params map.
If this datasource requires a number of parameters then this mehtod should check that they are all present and that they are all valid. If the datasource is a file reading data source then the extentions or mime types of any files specified should be checked. For example, a Shapefile datasource should check that the url param ends with shp, such tests should be case insensative.
@param params The full set of information needed to construct a livedata source. @return booean true if and only if this factory can process the resourceindicated by the param set and all the required params are pressent.
