Interface ScopedName

All Superinterfaces:

Comparable<GenericName>, GenericName

@UML(identifier="ScopedName",
     specification=ISO_19103)
public interface ScopedName
extends GenericName

A composite of a local name (as head) for locating another name space, and a generic name (as tail) valid in that name space. This definition allows for iteration. The tail may be either a local name or a scoped name. If it is a scoped name, then another another step towards a remote local name is taken. In this way, a scoped name may represent an arbitrarily distant local name simply by the number of times the tail() method evaluates to a ScopedName before finally terminating on a LocalName.

It may be seen that ScopedName is the means by which fully-qualified names are expressed. However, a ScopedName is not, in itself, what is commonly thought of as a fully qualified name. The ScopedName type is one link in the chain, not the entire chain. A scoped name is a fully qualified name only if its scope is global.

Example: The illustration below shows the head, tail, path and name of "org.opengis.util.Record".

org . opengis . util . Record head tail path tip

Method Details

head

@UML(identifier="head",
     obligation=MANDATORY,
     specification=ISO_19103)
LocalName head()

Returns the first element in the sequence of parsed names. The head element must exists in the same name space than this scoped name. In other words, the following relationship must holds:

• head().scope() equals this.scope()

This method is similar in purpose to Name.get(0) from the Java Naming and Directory Interface.

Example: If this name is "org.opengis.util.Record", then this method shall returns "org".

Specified by:

head in interface GenericName

Returns:

The first element in the list of parsed names.

Since:

2.2

tail

@UML(identifier="tail",
     obligation=MANDATORY,
     specification=ISO_19103)
GenericName tail()

Returns every elements of the parsed names list except for the head. In other words, the following relationship must holds:

• tail().getParsedNames() equals this.getParsedNames().sublist(1, depth)

This method is similar in purpose to Name.getSuffix(1) from the Java Naming and Directory Interface.

Returns:

All elements except the first one in the in the list of parsed names.

Since:

2.1

path

GenericName path()

Returns every elements of the parsed names list except for the tip. In other words, the following relationship must holds:

• tip().getParsedNames() equals this.getParsedNames().sublist(0, depth-1)

This method is similar in purpose to Name.getPrefix(size-1) from the Java Naming and Directory Interface.

Returns:

All elements except the last one in the in the list of parsed names.

Since:

2.1

Departure from OGC/ISO abstract specification:

Extension for convenience without introduction of new functionality

This method is not part of ISO specification. It has been added in GeoAPI as a complement of the ISO tail() method.

tip

LocalName tip()

Returns the last element in the sequence of parsed names.

This method is similar in purpose to Name.get(size-1) from the Java Naming and Directory Interface.

Specified by:

tip in interface GenericName

Returns:

The last element in the list of parsed names.

Since:

2.1

toString

@UML(identifier="scopedName",
     obligation=MANDATORY,
     specification=ISO_19103)
String toString()

Returns a locale-independent string representation of this scoped name. This method encapsulates the domain logic which formats the parsed names into a legal string representation of the name. There will be variants on this theme. XML aficionados may require URIs. For Java classes, a dotted notation is more appropriate, for C/C++, a double-colon, for directories, a forward or reverse slash, and for CRS, it will depend on the mode of expression: URN or Authority:Identifier notation.

Specified by:

toString in interface GenericName

Overrides:

toString in class Object

Returns:

A local-independent string representation of this name.
