XIncludeFilter

class XIncludeFilter extends XMLFilterImpl

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:

  1. XPointer is not supported.

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 horizontal chain of filters, not a vertical hierarchy of sub and superclasses.

To use this class:

e.g.

val includer = new XIncludeFilter(base)
includer setParent parser
includer setContentHandler new SAXXIncluder(System.out)
includer parse args(i)

  3. final def ##(): Int

    Equivalent to x.hashCode except for boxed numeric types and null.

    Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.

    returns

    a hash value consistent with ==

  9. final def asInstanceOf[T0]: T0

    Cast the receiver object to be of type T0.

    Cast the receiver object to be of type T0.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

    returns

    the receiver object.

  19. final def eq(arg0: AnyRef): Boolean

    Tests whether the argument (arg0) is a reference to the receiver object (this).

    Tests whether the argument (arg0) is a reference to the receiver object (this).

    The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

    • It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
    • For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
    • null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    returns

    true if the argument is a reference to the receiver object; false otherwise.
