Class Attributes2Impl

Contents
  • All Implemented Interfaces:
    Attributes, Attributes2

    public class Attributes2Impl
extends AttributesImpl
implements Attributes2
    SAX2 extension helper for additional Attributes information, implementing the Attributes2 interface.
    This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY.

    This is not part of core-only SAX2 distributions.

    The specified flag for each attribute will always be true, unless it has been set to false in the copy constructor or using setSpecified(int, boolean). Similarly, the declared flag for each attribute will always be false, except for defaulted attributes (specified is false), non-CDATA attributes, or when it is set to true using setDeclared(int, boolean). If you change an attribute's type by hand, you may need to modify its declared flag to match.

    Since:
    SAX 2.0 (extensions 1.1 alpha)

    • Constructor Detail

      • Attributes2Impl

        public Attributes2Impl()
        Construct a new, empty Attributes2Impl object.

      • Attributes2Impl

        public Attributes2Impl(Attributes atts)
        Copy an existing Attributes or Attributes2 object. If the object implements Attributes2, values of the specified and declared flags for each attribute are copied. Otherwise the flag values are defaulted to assume no DTD was used, unless there is evidence to the contrary (such as attributes with type other than CDATA, which must have been declared).

        This constructor is especially useful inside a startElement event.

        Parameters:
        atts - The existing Attributes object.

                  String localName)
        Returns the current value of an attribute's "specified" flag.
        Specified by:

        localName - The attribute's local name.
        Returns:
        current flag value
        Throws:
        IllegalArgumentException - When the supplied names do not identify an attribute.

      • isSpecified

        public boolean isSpecified(String qName)
        Returns the current value of an attribute's "specified" flag.
        Specified by:
        isSpecified in interface Attributes2
        Parameters:
        qName - The XML qualified (prefixed) name.
        Returns:
        current flag value
        Throws:
        IllegalArgumentException - When the supplied name does not identify an attribute.

      • setAttributes

        public void setAttributes(Attributes atts)
        Copy an entire Attributes object. The "specified" flags are assigned as true, and "declared" flags as false (except when an attribute's type is not CDATA), unless the object is an Attributes2 object. In that case those flag values are all copied.
        Overrides:
        setAttributes in class AttributesImpl
        Parameters:
        atts - The attributes to copy.
        See Also:
        AttributesImpl.setAttributes(org.xml.sax.Attributes)

      • removeAttribute

        public void removeAttribute(int index)
        Description copied from class: AttributesImpl
        Remove an attribute from the list.
        Overrides:
        removeAttribute in class AttributesImpl
        Parameters:
        index - The index of the attribute (zero-based).

      • setDeclared

        public void setDeclared(int index,
               boolean value)
        Assign a value to the "declared" flag of a specific attribute. This is normally needed only for attributes of type CDATA, including attributes whose type is changed to or from CDATA.
        Parameters:
        index - The index of the attribute (zero-based).
        value - The desired flag value.
        Throws:
        ArrayIndexOutOfBoundsException - When the supplied index does not identify an attribute.
        See Also:
        AttributesImpl.setType(int, java.lang.String)

      • setSpecified

        public void setSpecified(int index,
                boolean value)
        Assign a value to the "specified" flag of a specific attribute. This is the only way this flag can be cleared, except clearing by initialization with the copy constructor.
        Parameters:
        index - The index of the attribute (zero-based).
        value - The desired flag value.
        Throws:
