| Methods Summary |
|---|
| public void | clear()Removes all attributes from this Map.
map.clear();
|
| public java.lang.Object | clone()Returns a copy of the Attributes, implemented as follows:
public Object clone() { return new Attributes(this); }
Since the attribute names and values are themselves immutable,
the Attributes returned can be safely modified without affecting
the original.
return new Attributes(this);
|
| public boolean | containsKey(java.lang.Object name)Returns true if this Map contains the specified attribute name (key).
return map.containsKey(name);
|
| public boolean | containsValue(java.lang.Object value)Returns true if this Map maps one or more attribute names (keys)
to the specified value.
return map.containsValue(value);
|
| public java.util.Set | entrySet()Returns a Collection view of the attribute name-value mappings
contained in this Map.
return map.entrySet();
|
| public boolean | equals(java.lang.Object o)Compares the specified Attributes object with this Map for equality.
Returns true if the given object is also an instance of Attributes
and the two Attributes objects represent the same mappings.
return map.equals(o);
|
| public java.lang.Object | get(java.lang.Object name)Returns the value of the specified attribute name, or null if the
attribute name was not found.
return map.get(name);
|
| public java.lang.String | getValue(java.lang.String name)Returns the value of the specified attribute name, specified as
a string, or null if the attribute was not found. The attribute
name is case-insensitive.
This method is defined as:
return (String)get(new Attributes.Name((String)name));
return (String)get(new Attributes.Name((String)name));
|
| public java.lang.String | getValue(java.util.jar.Attributes$Name name)Returns the value of the specified Attributes.Name, or null if the
attribute was not found.
This method is defined as:
return (String)get(name);
return (String)get(name);
|
| public int | hashCode()Returns the hash code value for this Map.
return map.hashCode();
|
| public boolean | isEmpty()Returns true if this Map contains no attributes.
return map.isEmpty();
|
| public java.util.Set | keySet()Returns a Set view of the attribute names (keys) contained in this Map.
return map.keySet();
|
| public java.lang.Object | put(java.lang.Object name, java.lang.Object value)Associates the specified value with the specified attribute name
(key) in this Map. If the Map previously contained a mapping for
the attribute name, the old value is replaced.
return map.put((Attributes.Name)name, (String)value);
|
| public void | putAll(java.util.Map attr)Copies all of the attribute name-value mappings from the specified
Attributes to this Map. Duplicate mappings will be replaced.
// ## javac bug?
if (!Attributes.class.isInstance(attr))
throw new ClassCastException();
for (Map.Entry<?,?> me : (attr).entrySet())
put(me.getKey(), me.getValue());
|
| public java.lang.String | putValue(java.lang.String name, java.lang.String value)Associates the specified value with the specified attribute name,
specified as a String. The attributes name is case-insensitive.
If the Map previously contained a mapping for the attribute name,
the old value is replaced.
This method is defined as:
return (String)put(new Attributes.Name(name), value);
return (String)put(new Name(name), value);
