This method is used to compare the receiver object (this
)
with the argument object (arg0
) for equivalence.
The default implementations of this method is an equivalence relation:
x
of type Any
,
x.equals(x)
should return true
.x
and y
of type
Any
, x.equals(y)
should return true
if and only
if y.equals(x)
returns true
.x
, y
, and z
of type AnyRef
if x.equals(y)
returns true
and
y.equals(z)
returns
true
, then x.equals(z)
should return true
.
If you override this method, you should verify that
your implementation remains an equivalence relation.
Additionally, when overriding this method it is often necessary to
override hashCode
to ensure that objects that are
"equal" (o1.equals(o2)
returns true
)
hash to the same Int
(o1.hashCode.equals(o2.hashCode)
).
the object to compare against this object for equality.
true
if the receiver object is equivalent to the argument; false
otherwise.
Returns a hash code value for the object
Returns a hash code value for the object.
The default hashing algorithm is platform dependent.
Note that it is allowed for two objects to have identical hash
codes (o1.hashCode.equals(o2.hashCode)
) yet not be
equal (o1.equals(o2)
returns false
). A
degenerate implementation could always return 0
.
However, it is required that if two objects are equal
(o1.equals(o2)
returns true
) that they
have identical hash codes
(o1.hashCode.equals(o2.hashCode)
). Therefore, when
overriding this method, be sure to verify that the behavior is
consistent with the equals
method.
This utility method returns true if and only if this reader is currently inside a non-empty include element
This utility method returns true if and only if this reader is currently inside a non-empty include element. (This is not the same as being inside the node set which replaces the include element.) This is primarily needed for comments inside include elements. It must be checked by the actual LexicalHandler to see whether a comment is passed or not.
Returns a string representation of the object
Returns a string representation of the object.
The default representation is platform dependent.
This is a SAX filter which resolves all XInclude include elements before passing them on to the client application. Currently this class has the following known deviation from the XInclude specification:
Furthermore, I would definitely use a new instance of this class for each document you want to process. I doubt it can be used successfully on multiple documents. Furthermore, I can virtually guarantee that this class is not thread safe. You have been warned.
Since this class is not designed to be subclassed, and since I have not yet considered how that might affect the methods herein or what other protected methods might be needed to support subclasses, I have declared this class final. I may remove this restriction later, though the use-case for subclassing is weak. This class is designed to have its functionality extended via a a horizontal chain of filters, not a vertical hierarchy of sub and superclasses.
To use this class:
XIncludeFilter
object with a known base URLXMLReader
object from which the raw document will be read to thesetParent()
method of this object.ContentHandler
object to thesetContentHandler()
method of this object. This is the object which will receive events from the parsed and included document.LexicalHandler
object as the value of this object's http://xml.org/sax/properties/lexical-handler property. Also make sure yourLexicalHandler
asks this object for the status of each comment usinginsideIncludeElement
before doing anything with the comment.parse()
