      • getAttributeCount

        public int getAttributeCount()
        Description copied from interface: Attributes
        Get a count of the number of Attributes (not attribute values) in this Attributes object.
        Specified by:
        getAttributeCount in interface Attributes
        Returns:
        The attribute count.
      • getAttributeNames

        public Set<String> getAttributeNames()
        Description copied from interface: Attributes
        Get the attribute names, as a Set. This set is read-only; updating it will not change the underlying attributes collection.
        Specified by:
        getAttributeNames in interface Attributes
        Returns:
        The attribute names Set.
      • getAttribute

        public Attribute getAttribute​(String name)
        Description copied from interface: Attributes
        Get the Attribute object for the named attribute, if present.
        Specified by:
        getAttribute in interface Attributes
        Parameters:
        name - The name of the Attribute to get.
        Returns:
        The Attribute, or null if an attribute by that name is not present.
      • getAttributeValue

        public String getAttributeValue​(String name)
        Description copied from interface: Attributes
        Get the value of the specified attribute, if present. Note that, for multi-valued attributes, The value returned is whichever value is returned first by the underlying Set implementation; there are no ordering guarantees. As such, this method is primarily useful as a shorthand method for attributes known (or expected) by the caller to be single-valued. Note also that it is not possible, using this method, to distinguish between a missing attribute and an attribute that is present but has no values. In both cases, null is returned.
        Specified by:
        getAttributeValue in interface Attributes
        Parameters:
        name - The name of the attribute whose value is wanted.
        Returns:
        The attribute value, or null if the attribute is missing or has no values.
      • getAttributeValues

        public Set<String> getAttributeValues​(String name)
        Description copied from interface: Attributes
        Get the Set of values for the specified attribute, if present.
        Specified by:
        getAttributeValues in interface Attributes
        Parameters:
        name - The name of the attribute whose values are wanted.
        Returns:
        The Set of values, or null if the attribute is not present in the collection. If the attribute is present but has no values, an empty Set is returned.
      • getAttributeValuesAsArray

        public String[] getAttributeValuesAsArray​(String name)
        Description copied from interface: Attributes
        Get the set of values for the specified attribute as a String array.

        Parameters:
        name - The name of the attribute whose values are wanted.
        Returns:
        The array of values, or null if the attribute is not present in the collection. If the attribute is present but has no values, a zero-length array is returned.
