Method Detail

clone

public Object clone()
Description copied from class: Object
This method may be called to create a new copy of the Object. The typical behavior is as follows:

However, these are not strict requirements, and may be violated if necessary. Of the three requirements, the last is the most commonly violated, particularly if the subclass does not override Object.equals(Object).

If the Object you call clone() on does not implement Cloneable (which is a placeholder interface), then a CloneNotSupportedException is thrown. Notice that Object does not implement Cloneable; this method exists as a convenience for subclasses that do.

Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.

All array types implement Cloneable, and override this method as follows (it should never fail):

 public Object clone()
 {
   try
     {
       super.clone();
     }
   catch (CloneNotSupportedException e)
     {
       throw new InternalError(e.getMessage());
     }
 }
 

Overrides:
clone in class Object
Returns:
a copy of the Object
See Also:
Cloneable

containsAttribute

public boolean containsAttribute(Object name,
                                 Object value)
Description copied from interface: AttributeSet
Returns true if this AttributeSet contains an attribute with the specified name and value, false otherwise.

Specified by:
containsAttribute in interface AttributeSet
Parameters:
name - the name of the requested attribute
value - the value of the requested attribute
Returns:
true if this AttributeSet contains an attribute with the specified name and value, false otherwise

containsAttributes

public boolean containsAttributes(AttributeSet a)
Description copied from interface: AttributeSet
Returns true of this AttributeSet contains all of the specified attributes.

Specified by:
containsAttributes in interface AttributeSet
Parameters:
a - the requested attributes
Returns:
true of this AttributeSet contains all of the specified attributes

copyAttributes

public AttributeSet copyAttributes()
Description copied from interface: AttributeSet
Creates and returns a copy of this AttributeSet.

Specified by:
copyAttributes in interface AttributeSet
Returns:
a copy of this AttributeSet

equals

public boolean equals(Object obj)
Description copied from class: Object
Determine whether this Object is semantically equal to another Object.

There are some fairly strict requirements on this method which subclasses must follow:

This is typically overridden to throw a ClassCastException if the argument is not comparable to the class performing the comparison, but that is not a requirement. It is legal for a.equals(b) to be true even though a.getClass() != b.getClass(). Also, it is typical to never cause a NullPointerException.

In general, the Collections API (java.util) use the equals method rather than the == operator to compare objects. However, IdentityHashMap is an exception to this rule, for its own good reasons.

The default implementation returns this == o.

Overrides:
equals in class Object
Parameters:
obj - the Object to compare to
Returns:
whether this Object is semantically equal to another
See Also:
Object.hashCode()

getAttribute

public Object getAttribute(Object key)
Description copied from interface: AttributeSet
Returns the attribute with the specified key or null if no such attribute is defined in this AttributeSet and its resolving parents.

Specified by:
getAttribute in interface AttributeSet
Parameters:
key - the key of the attribute that is looked up
Returns:
the attribute with the specified key or null if no such attribute is defined in this AttributeSet and its resolving parents

getAttributeCount

public int getAttributeCount()
Description copied from interface: AttributeSet
Returns the number of attributes that are stored locally in this AttributeSet.

Specified by:
getAttributeCount in interface AttributeSet
Returns:
the number of attributes that are stored locally in this AttributeSet

getAttributeNames

public Enumeration<?> getAttributeNames()
Description copied from interface: AttributeSet
Returns the names of the attributes that are stored in this AttributeSet.

Specified by:
getAttributeNames in interface AttributeSet
Returns:
the names of the attributes that are stored in this AttributeSet

getResolveParent

public AttributeSet getResolveParent()
Description copied from interface: AttributeSet
Returns the resolving parent of this AttributeSet. If a key is not stored locally, then a AttributeSet.getAttribute(Object) request is resolved up in the resolving parent of this AttributeSet.

Specified by:
getResolveParent in interface AttributeSet
Returns:
the resolving parent of this AttributeSet

hashCode

public int hashCode()
Description copied from class: Object
Get a value that represents this Object, as uniquely as possible within the confines of an int.

There are some requirements on this method which subclasses must follow:

Notice that since hashCode is used in Hashtable and other hashing classes, a poor implementation will degrade the performance of hashing (so don't blindly implement it as returning a constant!). Also, if calculating the hash is time-consuming, a class may consider caching the results.

The default implementation returns System.identityHashCode(this)

Overrides:
hashCode in class Object
Returns:
the hash code for this Object
See Also:
Object.equals(Object), System.identityHashCode(Object)

isDefined

public boolean isDefined(Object key)
Description copied from interface: AttributeSet
Returns true if an attribute with the specified name is defined locally in this AttributeSet, without resolving through the resolving parents.

Specified by:
isDefined in interface AttributeSet
Returns:
true if an attribute with the specified name is defined locally in this AttributeSet

isEqual

public boolean isEqual(AttributeSet attr)
Description copied from interface: AttributeSet
Returns true if all of the attributes in attr are equal to the attributes in this AttributeSet, false otherwise.

Specified by:
isEqual in interface AttributeSet
Parameters:
attr - the attributes to be compared to this
Returns:
true if all of the attributes in attr are equal to the attributes in this AttributeSet, false otherwise

toString

public String toString()
Description copied from class: Object
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() and such.

It is typical, but not required, to ensure that this method never completes abruptly with a RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

Overrides:
toString in class Object
Returns:
the String representing this Object, which may be null
See Also:
Object.getClass(), Object.hashCode(), Class.getName(), Integer.toHexString(int)
