Method Detail

getSuffix

public static Name getSuffix(Name _name)

Returns the suffix of _name.

If _name may be represented as "a/b/c", with '/' as a separator, then getSuffix returns "c".

Parameters:

_name - a name;

Returns:

the last component of name.

getPrefix

public static Name getPrefix(Name _name)

Returns the prefix of _name.

If _name may be represented as "a/b/c", with '/' as a separator, then getPrefix returns "a/b".

Parameters:

_name - a name;

Returns:

the prefix composed of all the name components but the last one.

append

public static Name append(Name _name1,
                          Name _name2)

Appends _name1 and _name2.

Parameters:

_name1 - a name;

_name2 - another name;

Returns:

the concatenation of both names.

append

public static Name append(Name _name1,
                          java.lang.String _id,
                          char _separator)

toString

public static java.lang.String toString(Name _name,
                                        char _separator)

newName

public static Name newName(java.lang.String _id,
                           Name _subname)

Returns a new Name, using _id as identifier, and _subname as subname.

Parameters:

_id - a String identifier;

_subname - a name;

Returns:

a new Name, using _id as identifier, and _subname as subname.

newName

public static Name newName(java.lang.String _name,
                           char separator)

Creates a new name by parsing the provided string.

If separator == 0, _name is considered as a simple identifier, and this call returns newName(_name,null). If the name begins with the separator, the name is an absolute name (this only makes sense if contexts with a tree structure); otherwise, the name is relative.

Parameters:

_name - a string representing a name;

separator - a separator to parse it.

Returns:

a Name.
