java.lang.Objectorg.jacorb.notification.util.WildcardMap
public class WildcardMap
An Object that maps String Keys to Values. A WildcardMap cannot
contain duplicate
keys. Each Key has exactly one Entry associated. A Key can contain
the Wildcard Character '*' which matches zero or more characters of
the key. The WildcardMap supports two semantics of accessing the
entries. The first way is to ignore the special meaning of the
Wildcard character and to
just return the entries as they were inserted.
This way you could put some entries in a WildcardMap and fetch them
again using the Operation getNoExpansion()
:
WildcardMap wc = new WildcardMap(); wc.put("abc", new Integer(1)); wc.put("a*", new Integer(2)); wc.getNoExpansion("abc") => 1 wc.getNoExpansion("a*") => 2 wc.getNoExpansion("xyz") => nullThis behaviour is similiar to a
Map
.getWithExpansion()
. This Operations
matches the requested Key to all contained Keys. If the Key of an Entry
contains the Wildcard Character '*' it is matched
as expected by the semantic of '*'. The Operations returns an array
of all matching entries:
wc.getWithExpansion("abc") => [1,2] wc.getWithExpansion("a") => [2] wc.getWithExpansion("abcd") => [2] wc.getWithExpansion("xyz") => []
