Interface GenericName

  • All Superinterfaces:
    Comparable<GenericName>
    All Known Subinterfaces:
    LocalName, MemberName, ScopedName, TypeName
    All Known Implementing Classes:
    GenericName, LocalName, NamedIdentifier, ScopedName
    public interface GenericName
extends Comparable<GenericName>
    A sequence of identifiers rooted within the context of a namespace. This interface is similar in purpose to Name from the Java Naming and Directory Interface. All generic names:

    • carry an association with their scope in which they are considered local;
    • have the ability to provide a parsed version of themselves.

    Names are immutables. They may be fully qualified like "org.geotools.api.util.Record", or they may be relative to a scope like "util.Record" in the "org.opengis" scope. The illustration below shows all possible constructions for "org.geotools.api.util.Record".

    org .opengis .util .Record scope() getParsedNames()
    head tail global {"org", "opengis", "util", "Record"}
    path tip
    ScopedName
    scope head tail "org" {"opengis", "util", "Record"}
    path tip
    ScopedName
    scope head tail "org.opengis" {"util", "Record"}
    path tip
    ScopedName
    scope head "org.geotools.api.util" {"Record"}
    tip
    LocalName

    The natural ordering for generic names is implementation dependent. A recommended practice is to compare lexicographically each element in the list of parsed names. Specific attributes of the name, such as how it treats case, may affect the ordering. In general, two names of different classes may not be compared.

    • Method Detail

      • scope

        NameSpace scope()
        Returns the scope (name space) in which this name is local. The scope is set on creation and is not modifiable. The scope of a name determines where a name starts.

        Example: For a fully qualified name (a name having a global namespace) "org.geotools.api.util.Record", if this instance is the name "util.Record", then the scope of this instance has the name "org.opengis".

        Returns:
        The scope of this name.
        Since:
        GeoAPI 2.1

      • depth

        int depth()
        Indicates the number of levels specified by this name. The depth is the size of the list returned by the getParsedNames() method. As such it is a derived parameter. For any LocalName, it is always one. For a ScopedName it is some number greater than or equal to 2.

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

        Example: If this name is "org.geotools.api.util.Record", then this method shall returns 4. If this name is "util.Record" in scope "org.opengis", then this method shall returns 2.

        Returns:
        The depth of this name.
        Since:
        GeoAPI 2.1

      • getParsedNames

        List<? extends LocalName> getParsedNames()
        Returns the sequence of local names making this generic name. The length of this sequence is the depth. It does not include the scope.

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

        Example: If this name is "org.geotools.api.util.Record", then this method shall returns a list containing {"org", "opengis", "util", "Record"} elements in that iteration order. If this name is "util.Record" in scope "org.opengis", then this method shall returns a list containing only {"util", "Record"} elements.

        Returns:
        The local names making this generic name, without the scope. Shall never be null neither empty.

      • head

        LocalName head()
        Returns the first element in the sequence of parsed names. For any LocalName, this is always this.

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

        Example: If this name is "org.geotools.api.util.Record" (no matter its scope), then this method shall returns "org".

        Returns:
        The first element in the list of parsed names.
        Since:
        GeoAPI 2.2

      • tip

        LocalName tip()
        Returns the last element in the sequence of parsed names. For any LocalName, this is always this.

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

        Example: If this name is "org.geotools.api.util.Record" (no matter its scope), then this method shall returns "Record".

        Returns:
        The last element in the list of parsed names.
        Since:
        GeoAPI 2.1

      • toFullyQualifiedName

        GenericName toFullyQualifiedName()
        Returns a view of this name as a fully-qualified name. The scope of a fully qualified name must be global. If the scope of this name is already global, then this method shall returns this.

        Example: If this name is "util.Record" (depth of two) and its scope has the name "org.opengis", then the fully qualified name shall be "org.geotools.api.util.Record".

        Returns:
        The fully-qualified name (never null).
        Since:
        GeoAPI 2.1

      • push

        ScopedName push​(GenericName scope)
        Returns this name expanded with the specified scope. One may represent this operation as a concatenation of the specified scope with this. In pseudo-code, the following relationships must hold (the last one is specific to ScopedName):

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

        Example: If this name is "util.Record" and the given scope argument is "org.opengis", then this.push(scope) shall returns "org.geotools.api.util.Record".

        Parameters:
        scope - The name to use as prefix.
        Returns:
        A concatenation of the given name with this name.
        Since:
        GeoAPI 2.1

      • toString

        String toString()
        Returns a string representation of this generic name. This string representation is local-independant. It contains all elements listed by getParsedNames() separated by a namespace-dependant character (usually : or /). This rule implies that the result may or may not be fully qualified. Special cases:

        • toFullyQualifiedName().toString() is garanteed to contains the scope (if any).
        • name.toString() is garanteed to not contains any scope.
        Overrides:
        toString in class Object
        Returns:
        A local-independant string representation of this name.

      • toInternationalString

        InternationalString toInternationalString()
        Returns a local-dependent string representation of this generic name. This string is similar to the one returned by toString() except that each element has been localized in the specified locale. If no international string is available, then this method shall returns an implementation mapping to toString() for all locales.

        Example: An implementation may want to localize the "My Documents" directory name into "Mes Documents" on French installation of Windows operating system.

        Returns:
        A localizable string representation of this name.
