public class QName
extends java.lang.Object
implements java.io.Serializable

Class to represent a qualified name: "The name of an internal XSLT object, specifically a named template (see [7 Named Templates]), a mode (see [6.7 Modes]), an attribute set (see [8.1.4 Named Attribute Sets]), a key (see [14.2 Keys]), a locale (see [14.3 Number Formatting]), a variable or a parameter (see [12 Variables and Parameters]) is specified as a QName. If it has a prefix, then the prefix is expanded into a URI reference using the namespace declarations in effect on the attribute in which the name occurs. The expanded name consisting of the local part of the name and the possibly null URI reference is used as the name of the object. The default namespace is not used for unprefixed names."

### QName

    public QName(java.lang.String qname)

  Construct a QName from a string, without namespace resolution. Good for a few odd cases.

### QName

    public QName(java.lang.String qname,
                 java.util.Stack namespaces)

  Construct a QName from a string, resolving the prefix using the given namespace stack. The default namespace is not resolved.

### QName

    public QName(java.lang.String qname,
                 org.w3c.dom.Element namespaceContext,
                 PrefixResolver resolver)

  Construct a QName from a string, resolving the prefix using the given namespace stack. The default namespace is not resolved.

### QName

    public QName(java.lang.String qname,
                 PrefixResolver resolver)

  Construct a QName from a string, resolving the prefix using the given namespace stack. The default namespace is not resolved.

Method Detail

### hashCode

    public int hashCode()

  Return the cached hashcode of the qualified name.
  Overrides:
    hashCode in class java.lang.Object

### equals

    public boolean equals(java.lang.Object obj)

  Override equals and agree that we're equal if the passed object is a string and it matches the name of the arg.
  Overrides:
    equals in class java.lang.Object

### equals

    public boolean equals(java.lang.String ns,
                          java.lang.String localPart)

  Override equals and agree that we're equal if the passed object is a string and it matches the name of the arg.

### equals

    public boolean equals(QName qname)

  Override equals and agree that we're equal if the passed object is a QName and it matches the name of the arg.

### toString

    public java.lang.String toString()

  Return the string representation of the namespace. Performs string concatenation, so beware of performance issues.
  Overrides:
    toString in class java.lang.Object
