Class LargeAttributeMap

java.lang.Object
net.sf.saxon.om.LargeAttributeMap
All Implemented Interfaces:
Iterable<AttributeInfo>, AttributeMap
public class LargeAttributeMap extends Object implements AttributeMap
An implementation of AttributeMap suitable for larger collections of attributes (say, more than five). This provides direct access to an attribute by name, avoiding the cost of a sequential search. The map preserves the order of insertion of attributes: this is done by maintaining a doubly-linked list of attributes in insertion order (when an attribute is replaced by another with the same name, it currently occupies the position of the original; but this is not guaranteed).

  • Constructor Details

  • Method Details

    • size

      public int size()
      Return the number of attributes in the map.
      Specified by:
      size in interface AttributeMap
      Returns:
      The number of attributes in the map.

    • get

      public AttributeInfo get(NodeName name)
      Description copied from interface: AttributeMap
      Get the attribute with a given name, if it exists
      Specified by:
      get in interface AttributeMap
      Parameters:
      name - the name of the required attribute
      Returns:
      the required attribute if it exists

    • get

      public AttributeInfo get(NamespaceUri uri, String local)
      Description copied from interface: AttributeMap
      Get the attribute with a given name, if it exists
      Specified by:
      get in interface AttributeMap
      Parameters:
      uri - the namespace part of the name of the required attribute
      local - the local part of the name of the required attribute
      Returns:
      the required attribute if it exists

    • getByFingerprint

      public AttributeInfo getByFingerprint(int fingerprint, NamePool namePool)
      Specified by:
      getByFingerprint in interface AttributeMap

    • put

      public AttributeMap put(AttributeInfo att)
      Description copied from interface: AttributeMap
      Replace or add an attribute, to create a new AttributeMap
      Specified by:
      put in interface AttributeMap
      Parameters:
      att - the attribute to be added or replaced
      Returns:
      the new AttributeMap

    • remove

      public AttributeMap remove(NodeName name)
      Description copied from interface: AttributeMap
      Remove an existing attribute, to create a new AttributeMap
      Specified by:
      remove in interface AttributeMap
      Parameters:
      name - the name of the attribute to be removed (if it exists)
      Returns:
      a new attribute map in which the specified attribute is omitted. If the attribute map contains no attribute with the given name, the input attribute map (or one equivalent to it) is returned unchanged

    • iterator

      public Iterator<AttributeInfo> iterator()
      Specified by:
      iterator in interface Iterable<AttributeInfo>

    • asList

      public ArrayList<AttributeInfo> asList()
      Description copied from interface: AttributeMap
      Get the contents of the AttributeMap as a list of AttributeInfo objects.

      The order of the returned list must be consistent with document order, with the order of the attribute axis, and with position-based retrieval of individual AttributeInfo objects; multiple calls are not required to return the same list, but they must be consistent in their ordering.

      Modifying the returned list has no effect on the AttributeMap

      Specified by:
      asList in interface AttributeMap
      Returns:
      a list of attributes in the AttributeMap

    • toString

      public String toString()
      Overrides:
      toString in class Object
