Class Attributes2Impl

java.lang.Object
org.xml.sax.helpers.AttributesImpl
org.xml.sax.ext.Attributes2Impl
All Implemented Interfaces:
Attributes, Attributes2
public class Attributes2Impl extends AttributesImpl implements Attributes2
SAX2 extension helper for additional Attributes information, implementing the Attributes2 interface.

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:
1.5, SAX 2.0 (extensions 1.1 alpha)

  • Constructor Details

    • 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.

  • Method Details

      Specified by:
      isDeclared in interface Attributes2
      Parameters:
      index - The attribute index (zero-based).
      Returns:
      true if the attribute was declared in the DTD, false otherwise.

      Specified by:
      isDeclared in interface Attributes2
      Parameters:
      uri - The Namespace URI, or the empty string if the name has no Namespace URI.
      localName - The attribute's local name.

      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.

      atts - The attributes to copy.
      See Also:

    • addAttribute

      public void addAttribute(String uri, String localName, String qName, String type, String value)
      Add an attribute to the end of the list, setting its "specified" flag to true. To set that flag's value to false, use setSpecified(int, boolean).

      Unless the attribute type is CDATA, this attribute is marked as being declared in the DTD. To set that flag's value to true for CDATA attributes, use setDeclared(int, boolean).

      Overrides:
      addAttribute in class AttributesImpl
      Parameters:
      uri - The Namespace URI, or the empty string if none is available or Namespace processing is not being performed.

      qName - The qualified (prefixed) name, or the empty string if qualified names are not available.
      type - The attribute type as a string.
      value - The attribute value.
      See Also:

    • 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:

    • 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:
      ArrayIndexOutOfBoundsException - When the supplied index does not identify an attribute.
