Name

Class Overview

The Name interface represents a generic name -- an ordered sequence of components. It can be a composite name (names that span multiple namespaces), or a compound name (names that are used within individual hierarchical naming systems).

There can be different implementations of Name; for example, composite names, URLs, or namespace-specific compound names.

The components of a name are numbered. The indexes of a name with N components range from 0 up to, but not including, N. This range may be written as [0,N). The most significant component is at index 0. An empty name has no components.

None of the methods in this interface accept null as a valid value for a parameter that is a name or a name component. Likewise, methods that return a name or name component never return null.

An instance of a Name may not be synchronized against concurrent multithreaded access if that access is not read-only.

Public Methods

public abstract Name add (int posn, String comp)

Adds a single component at a specified position within this name. Components of this name at or after the index of the new component are shifted up by one (away from index 0) to accommodate the new component.

Parameters
posn the index at which to add the new component. Must be in the range [0,size()].
comp the component to add
Returns
  • the updated name (not a new one)
Throws
ArrayIndexOutOfBoundsException if posn is outside the specified range
InvalidNameException if adding comp would violate the syntax rules of this name

public abstract Name add (String comp)

Adds a single component to the end of this name.

Parameters
comp the component to add
Returns
  • the updated name (not a new one)
Throws
InvalidNameException if adding comp would violate the syntax rules of this name

public abstract Name addAll (int posn, Name n)

Adds the components of a name -- in order -- at a specified position within this name. Components of this name at or after the index of the first new component are shifted up (away from 0) to accommodate the new components.

Parameters
posn the index in this name at which to add the new components. Must be in the range [0,size()].
n the components to add
Returns
  • the updated name (not a new one)
Throws
ArrayIndexOutOfBoundsException if posn is outside the specified range
InvalidNameException if n is not a valid name, or if the addition of the components would violate the syntax rules of this name

public abstract Name addAll (Name suffix)

Adds the components of a name -- in order -- to the end of this name.

Parameters
suffix the components to add
Returns
  • the updated name (not a new one)
Throws
InvalidNameException if suffix is not a valid name, or if the addition of the components would violate the syntax rules of this name

public abstract Object clone ()

Generates a new copy of this name. Subsequent changes to the components of this name will not affect the new copy, and vice versa.

Returns
  • a copy of this name

public abstract int compareTo (Object obj)

Compares this name with another name for order. Returns a negative integer, zero, or a positive integer as this name is less than, equal to, or greater than the given name.

As with Object.equals(), the notion of ordering for names depends on the class that implements this interface. For example, the ordering may be based on lexicographical ordering of the name components. 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.

Parameters
obj the non-null object to compare against.
Returns
  • a negative integer, zero, or a positive integer as this name is less than, equal to, or greater than the given name
Throws
ClassCastException if obj is not a Name of a type that may be compared with this name

public abstract boolean endsWith (Name n)

Determines whether this name ends with a specified suffix. A name n is a suffix if it is equal to getSuffix(size()-n.size()).

Parameters
n the name to check
Returns
  • true if n is a suffix of this name, false otherwise

public abstract String get (int posn)

Retrieves a component of this name.

Parameters
posn the 0-based index of the component to retrieve. Must be in the range [0,size()).
Returns
  • the component at index posn
Throws
ArrayIndexOutOfBoundsException if posn is outside the specified range

public abstract Enumeration<String> getAll ()

Retrieves the components of this name as an enumeration of strings. The effect on the enumeration of updates to this name is undefined. If the name has zero components, an empty (non-null) enumeration is returned.

Returns
  • an enumeration of the components of this name, each a string

public abstract Name getPrefix (int posn)

Creates a name whose components consist of a prefix of the components of this name. Subsequent changes to this name will not affect the name that is returned and vice versa.

Parameters
posn the 0-based index of the component at which to stop. Must be in the range [0,size()].
Returns
  • a name consisting of the components at indexes in the range [0,posn).
Throws
ArrayIndexOutOfBoundsException if posn is outside the specified range

public abstract Name getSuffix (int posn)

Creates a name whose components consist of a suffix of the components in this name. Subsequent changes to this name do not affect the name that is returned and vice versa.

Parameters
posn the 0-based index of the component at which to start. Must be in the range [0,size()].
Returns
  • a name consisting of the components at indexes in the range [posn,size()). If posn is equal to size(), an empty name is returned.
Throws
ArrayIndexOutOfBoundsException if posn is outside the specified range

public abstract boolean isEmpty ()

Determines whether this name is empty. An empty name is one with zero components.

Returns
  • true if this name is empty, false otherwise

public abstract Object remove (int posn)

Removes a component from this name. The component of this name at the specified position is removed. Components with indexes greater than this position are shifted down (toward index 0) by one.

Parameters
posn the index of the component to remove. Must be in the range [0,size()).
Returns
  • the component removed (a String)
Throws
ArrayIndexOutOfBoundsException if posn is outside the specified range
InvalidNameException if deleting the component would violate the syntax rules of the name

public abstract int size ()

Returns the number of components in this name.

Returns
  • the number of components in this name

public abstract boolean startsWith (Name n)

Determines whether this name starts with a specified prefix. A name n is a prefix if it is equal to getPrefix(n.size()).

Parameters
n the name to check
Returns
  • true if n is a prefix of this name, false otherwise
