      Get the attribute with a given name, if it exists

      the required attribute if it exists

    • getByFingerprint

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

    • getValue

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

    • getValue

      public String getValue(String local)
      Description copied from interface: AttributeMap
      Get the value of a no-namespace attribute with a given local name, if it exists
      Specified by:
      getValue in interface AttributeMap
      Parameters:
      local - the local part of the name of the required attribute; the attribute must be in no namespace
      Returns:
      the value of the required attribute if it exists, or null otherwise

    • 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

    • verify

      public void verify()
      Description copied from interface: AttributeMap
      Verify the consistency of the attribute map. This performs an implementation-defined set of checks that might include checking for duplicates, checking that names are well-formed, checking for inappropriate use of the xml and xmlns namespaces, and checking the constraint that attributes in a namespace have a prefix, and vice versa. The default implementation does nothing.
      Specified by:
      verify in interface AttributeMap

    • iterator

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

    • apply

      public AttributeMap apply(Function<AttributeInfo,AttributeInfo> mapper)
      Description copied from interface: AttributeMap
      Apply a function to every attribute in an attribute map, returning a new attribute map
      Specified by:
      apply in interface AttributeMap
      Parameters:
      mapper - the mapping function to be applied to each attribute in the attribute map
      Returns:
      the attribute containing the attributes after the mapping function has been applied

    • 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

    • itemAt

      public AttributeInfo itemAt(int index)
      Description copied from interface: AttributeMap
      Get the AttributeInfo with a given index.
      Specified by:
      itemAt in interface AttributeMap
      Parameters:
      index - the index position, zero-based. The order of index positions of attributes in an attribute map reflects document order.
      Returns:
      the AttributeInfo at the given position. In an immutable tree the result will always be equivalent to calling asList().get(index). However, if the tree has been modified, then the index values of the attributes may not be contiguous.
