Interface AttributeCollection

  • All Known Implementing Classes:
    AttributeCollectionImpl, TinyAttributeCollection

    public interface AttributeCollection
    AttributeCollection represents the collection of attributes available on a particular element node. It is modelled on the SAX2 Attributes interface, but is extended firstly to work with Saxon NamePools, and secondly to provide type information as required by the XPath 2.0 data model.

      • getNameCode

        int getNameCode​(int index)
        Get the namecode of an attribute (by position).
        Parameters:
        index - The position of the attribute in the list.
        Returns:
        The name code of the attribute, or -1 if there is no attribute at that position.
      • getTypeAnnotation

        int getTypeAnnotation​(int index)
        Get the type annotation of an attribute (by position).
        Parameters:
        index - The position of the attribute in the list.
        Returns:
        The type annotation, as the fingerprint of the type name. The bit NodeInfo.IS_DTD_TYPE represents a DTD-derived type.
      • getLocationId

        int getLocationId​(int index)
        Get the locationID of an attribute (by position)
        Parameters:
        index - The position of the attribute in the list.
        Returns:
        The location identifier of the attribute. This can be supplied to a LocationProvider in order to obtain the actual system identifier and line number of the relevant location
      • getSystemId

        java.lang.String getSystemId​(int index)
        Get the systemId part of the location of an attribute, at a given index.

        Attribute location information is not available from a SAX parser, so this method is not useful for getting the location of an attribute in a source document. However, in a Saxon result document, the location information represents the location in the stylesheet of the instruction used to generate this attribute, which is useful for debugging.

        Parameters:
        index - the required attribute
        Returns:
        the systemId of the location of the attribute
      • getLineNumber

        int getLineNumber​(int index)
        Get the line number part of the location of an attribute, at a given index.

        Attribute location information is not available from a SAX parser, so this method is not useful for getting the location of an attribute in a source document. However, in a Saxon result document, the location information represents the location in the stylesheet of the instruction used to generate this attribute, which is useful for debugging.

        Parameters:
        index - the required attribute
        Returns:
        the line number of the location of the attribute
      • getProperties

        int getProperties​(int index)
        Get the properties of an attribute (by position)
        Parameters:
        index - The position of the attribute in the list.
        Returns:
        The properties of the attribute. This is a set of bit-settings defined in class ReceiverOptions. The most interesting of these is {ReceiverOptions.DEFAULTED_ATTRIBUTE, which indicates an attribute that was added to an element as a result of schema validation.
      • getPrefix

        java.lang.String getPrefix​(int index)
