equals

public boolean equals(java.lang.Object obj)

An instance of AttrImpl can act as an OMAttribute and as well as an org.w3c.dom.Attr. So we first check if the object to compare with (obj) is of type OMAttribute (this includes instances of OMAttributeImpl or AttrImpl (instances of this class)). If so we check for the equality of namespaces first (note that if the namespace of this instance is null then for the obj to be equal its namespace must also be null). This condition solely doesn't determine the equality. So we check for the equality of names and values (note that the value can also be null in which case the same argument holds as that for the namespace) of the two instances. If all three conditions are met then we say the two instances are equal.

If obj is of type org.w3c.dom.Attr then we perform the same equality check as before. Note that, however, the implementation of the test for equality in this case is little different than before.

If obj is neither of type OMAttribute nor of type org.w3c.dom.Attr then we return false.

Overrides:

equals in class java.lang.Object

Parameters:

obj - The object to compare with this instance

Returns:

True if the two objects are equal or else false. The equality is checked as explained above.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
