Class NameOfNode

java.lang.Object
net.sf.saxon.om.NameOfNode
All Implemented Interfaces:
IdentityComparable, NodeName
public class NameOfNode extends Object implements NodeName
An implementation of NodeName that gets the name of an existing NodeInfo object. Useful when nodes are copied. However, it's not safe to use when the node is mutable.

  • Method Details

    • makeName

      public static NodeName makeName(NodeInfo node)
      Make a NodeName object based on the name of a supplied node.
      Parameters:
      node - the supplied node
      Returns:
      a NameOfNode object unless the node is mutable, in which case an immutable name is returned.

    • getPrefix

      public String getPrefix()
      Get the prefix of the QName.
      Specified by:
      getPrefix in interface NodeName
      Returns:
      the prefix. Returns the empty string if the name is unprefixed.

    • getNamespaceUri

      public NamespaceUri getNamespaceUri()
      Get the namespace URI of the QName.
      Specified by:
      getNamespaceUri in interface NodeName
      Returns:
      the URI. Returns the empty string to represent the no-namespace

    • getLocalPart

      public String getLocalPart()
      Get the local part of the QName
      Specified by:
      getLocalPart in interface NodeName
      Returns:
      the local part of the QName

    • getDisplayName

      public String getDisplayName()
      Get the display name, that is the lexical QName in the form [prefix:]local-part
      Specified by:
      getDisplayName in interface NodeName
      Returns:
      the lexical QName

    • getStructuredQName

      public StructuredQName getStructuredQName()
      Get the name in the form of a StructuredQName
      Specified by:
      getStructuredQName in interface NodeName
      Returns:
      the name in the form of a StructuredQName

    • hasURI

      public boolean hasURI(NamespaceUri ns)
      Test whether this name is in a given namespace
      Specified by:
      hasURI in interface NodeName
      Parameters:
      ns - the namespace to be tested against
      Returns:
      true if the name is in the specified namespace

    • getNamespaceBinding

      public NamespaceBinding getNamespaceBinding()
      Get a NamespaceBinding whose (prefix, uri) pair are the prefix and URI of this node name
      Specified by:
      getNamespaceBinding in interface NodeName
      Returns:
      the corresponding NamespaceBinding

    • hasFingerprint

      public boolean hasFingerprint()
      Ask whether this node name representation has a known namecode and fingerprint
      Specified by:
      hasFingerprint in interface NodeName
      Returns:
      true if the methods getFingerprint() and getNameCode() will return a result other than -1

    • getFingerprint

      public int getFingerprint()
      Get the fingerprint of this name if known. This method should not to any work to allocate a fingerprint if none is already available
      Specified by:
      getFingerprint in interface NodeName
      Returns:
      the fingerprint if known; otherwise -1

    • obtainFingerprint

      public int obtainFingerprint(NamePool namePool)
      Get the nameCode of this name, allocating a new code from the namepool if necessary
      Specified by:
      obtainFingerprint in interface NodeName
      Parameters:
      namePool - the NamePool used to allocate the name
      Returns:
      a nameCode for this name, newly allocated if necessary

    • hashCode

      public int hashCode()
      Returns a hash code value for the object.
      Overrides:
      hashCode in class Object

    • equals

      public boolean equals(Object obj)
      Indicates whether some other object is "equal to" this one.
      Overrides:
      equals in class Object

    • isIdentical

      public boolean isIdentical(IdentityComparable other)
      Determine whether two IdentityComparable objects are identical. This is a stronger test than equality (even schema-equality); for example two dateTime values are not identical unless they are in the same timezone.
      Specified by:
      isIdentical in interface IdentityComparable
      Parameters:
      other - the value to be compared with
      Returns:
      true if the two values are identical, false otherwise

    • identityHashCode

      public int identityHashCode()
      Get a hashCode that offers the guarantee that if A.isIdentical(B), then A.identityHashCode() == B.identityHashCode()
      Specified by:
      identityHashCode in interface IdentityComparable
      Returns:
      a hashCode suitable for use when testing for identity.
