Class QName

  • All Implemented Interfaces:
    Serializable
    public class QName
extends Object
implements Serializable
    NOTE: copied from Apache AXIS until QName is really standard in some JDK version ... QName class represents the value of a qualified name as specified in XML Schema Part2: Datatypes specification.

    The value of a QName contains a namespaceURI, a localPart and a prefix. The localPart provides the local part of the qualified name. The namespaceURI is a URI reference identifying the namespace.

        public QName​(String localPart)
        Constructor for the QName.

        namespaceURI - Namespace URI for the QName
        localPart - Local part of the QName.

      • QName

        public QName​(String namespaceURI,
             String localPart,
             String prefix)
        Constructor for the QName.

        namespaceURI - Namespace URI for the QName
        localPart - Local part of the QName.
        prefix - Prefix of the QName.

    • Method Detail

      • getNamespaceURI

        public String getNamespaceURI()
        Gets the Namespace URI for this QName
        Returns:
        Namespace URI

      • getLocalPart

        public String getLocalPart()
        Gets the Local part for this QName
        Returns:
        Local part

      • getPrefix

        public String getPrefix()
        Gets the Prefix for this QName
        Returns:
        Prefix

      • toString

        public String toString()
        Returns a string representation of this QName
        Overrides:
        toString in class Object
        Returns:
        a string representation of the QName

      • equals

        public final boolean equals​(Object obj)
        Tests this QName for equality with another object.

        If the given object is not a QName or is null then this method returns false.

        For two QNames to be considered equal requires that both localPart and namespaceURI must be equal. This method uses String.equals to check equality of localPart and namespaceURI. Any class that extends QName is required to satisfy this equality contract.

        This method satisfies the general contract of the Object.equals method.

        Overrides:
        equals in class Object
        Parameters:
        obj - the reference object with which to compare
        Returns:
        true if the given object is identical to this QName: false otherwise.

      • valueOf

        public static QName valueOf​(String s)
        Returns a QName holding the value of the specified String.

        The string must be in the form returned by the QName.toString() method, i.e. "{namespaceURI}localPart", with the "{namespaceURI}" part being optional.

        This method doesn't do a full validation of the resulting QName. In particular, it doesn't check that the resulting namespace URI is a legal URI (per RFC 2396 and RFC 2732), nor that the resulting local part is a legal NCName per the XML Namespaces specification.

        Parameters:
        s - the string to be parsed
        Returns:
        QName corresponding to the given String
        Throws:
        IllegalArgumentException - If the specified String cannot be parsed as a QName

      • hashCode

        public final int hashCode()
        Returns a hash code value for this QName object. The hash code is based on both the localPart and namespaceURI parts of the QName. This method satisfies the general contract of the Object.hashCode method.
        Overrides:
        hashCode in class Object
        Returns:
        a hash code value for this Qname object
