The IDLnetOGCWMS::Init method initializes an IDLnetOGCWMS object, which provides a way to connect to and return information from a remote Open Geospatial Consortium Web Map Service server.
See Making OGC WMS Server Requests for instructions on how to use object methods and properties to configure and complete requests for information from a remote OGC WMS server.
Note: Init methods are special lifecycle methods, and as such cannot be called outside the context of object creation. This means that in most cases, you cannot call the Init method directly. There is one exception to this rule: If you write your own subclass of this class, you can call the Init method from within the Init method of the subclass.
Obj = OBJ_NEW( 'IDLnetOGCWMS' [, PROPERTY=value] )
or
Result = Obj->[IDLnetOGCWMS::]Init([, PROPERTY=value] ) (In a lifecycle method only.)
When this method is called indirectly, as part of the call to the OBJ_NEW function, the return value is an object reference to the newly-created object.
When called directly within a subclass Init method, the return value is 1 if initialization was successful, or zero otherwise.
None
Any property listed under IDLnetOGCWMS Properties that contains the word “Yes” in the “Init” column of the properties table can be initialized during object creation using this method. To initialize the value of a property, specify the property name as a keyword set equal to the appropriate property value.
