Class Overview

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.

Public Constructors

public Attributes2Impl ()

Construct a new, empty Attributes2Impl object.

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.

Public Methods

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).

Parameters
uri The Namespace URI, or the empty string if none is available or Namespace processing is not being performed.
localName The local name, or the empty string if 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

public boolean isDeclared (int index)

Returns false unless the attribute was declared in the DTD. This helps distinguish two kinds of attributes that SAX reports as CDATA: ones that were declared (and hence are usually valid), and those that were not (and which are never valid).

Parameters
index The attribute index (zero-based).
Returns
  • true if the attribute was declared in the DTD, false otherwise.

public boolean isDeclared (String qName)

Returns false unless the attribute was declared in the DTD. This helps distinguish two kinds of attributes that SAX reports as CDATA: ones that were declared (and hence are usually valid), and those that were not (and which are never valid).

Parameters
qName The XML qualified (prefixed) name.
Returns
  • true if the attribute was declared in the DTD, false otherwise.

public boolean isDeclared (String uri, String localName)

Returns false unless the attribute was declared in the DTD. This helps distinguish two kinds of attributes that SAX reports as CDATA: ones that were declared (and hence are usually valid), and those that were not (and which are never valid).

Remember that since DTDs do not "understand" namespaces, the namespace URI associated with an attribute may not have come from the DTD. The declaration will have applied to the attribute's qName.

Parameters
uri The Namespace URI, or the empty string if the name has no Namespace URI.
localName The attribute's local name.
Returns
  • true if the attribute was declared in the DTD, false otherwise.

public boolean isSpecified (String qName)

Returns the current value of an attribute's "specified" flag.

Parameters
qName The XML qualified (prefixed) name.
Returns
  • current flag value
Throws
IllegalArgumentException When the supplied name does not identify an attribute.

public boolean isSpecified (int index)

Returns the current value of an attribute's "specified" flag.

Parameters
index The attribute index (zero-based).
Returns
  • current flag value
Throws
ArrayIndexOutOfBoundsException When the supplied index does not identify an attribute.

public boolean isSpecified (String uri, String localName)

Returns the current value of an attribute's "specified" flag.

Parameters
uri The Namespace URI, or the empty string if the name has no Namespace URI.
localName The attribute's local name.
Returns
  • current flag value
Throws
IllegalArgumentException When the supplied names do not identify an attribute.

public void removeAttribute (int index)

Remove an attribute from the list.

Parameters
index The index of the attribute (zero-based).

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.

Parameters
atts The attributes to copy.
See Also

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

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.
