public interface Attributes

This interface represents a list of XML attributes.

It is a more efficient version of org.xml.sax.Attributes with CharArray/CharSequence instead of the String to avoid forcing dynamic object allocations.

Method Detail

getLength

int getLength()

Returns the number of attributes in this list of attributes.

Returns:

the number of attributes.

getURI

CharArray getURI(int index)

Looks up an attribute's Namespace URI by index.

Parameters:

index - the attribute index (zero-based).

Returns:

the Namespace URI, or an empty character sequence if none is available, or null if the index is out of range.

See Also:

getLength()

getLocalName

CharArray getLocalName(int index)

Looks up an attribute's local name by index.

Parameters:

index - the attribute index (zero-based).

Returns:

the local name, or an empty character sequence if Namespace processing is not being performed, or null if the index is out of range.

See Also:

getLength()

getQName

CharArray getQName(int index)

Looks up an attribute's XML 1.0 qualified name by index.

Parameters:

index - the attribute index (zero-based).

Returns:

the XML 1.0 qualified name, or an empty character sequence if none is available, or null if the index is out of range.

See Also:

getLength()

getType

CharArray getType(int index)

Looks up an attribute's type by index.

The attribute type is one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", or "NOTATION" (always in upper case).

If the parser has not read a declaration for the attribute, or if the parser does not report attribute types, then it must return the value "CDATA" as stated in the XML 1.0 Recommentation (clause 3.3.3, "Attribute-TextBuilder Normalization").

For an enumerated attribute that is not a notation, the parser will report the type as "NMTOKEN".

Parameters:

index - the attribute index (zero-based).

Returns:

the attribute's type as a string, or null if the index is out of range.

See Also:

getLength()

getValue

CharArray getValue(int index)

Looks up an attribute's value by index.

If the attribute value is a list of tokens (IDREFS, ENTITIES, or NMTOKENS), the tokens will be concatenated into a single string with each token separated by a single space.

Parameters:

index - the attribute index (zero-based).

Returns:

the attribute's value as a character sequence, null if the index is out of range.

See Also:

getLength()

getIndex

int getIndex(CharSequence uri,
           CharSequence localName)

Looks up the index of an attribute by namespace name (convenience method). This method returns the index of the attribute whose uri/localName have the same character content as the specified uri/localName.

Parameters:

uri - the Namespace URI, or an empty character sequence if the name has no Namespace URI.

localName - the attribute's local name.

Returns:

the index of the attribute, or -1 if it does not appear in the list.

getIndex

int getIndex(CharSequence qName)

Looks up the index of an attribute by XML 1.0 qualified name (convenience method). This method returns the index of the attribute whose name has the same character content as the specified qName.

Parameters:

qName - the qualified (prefixed) name.

Returns:

the index of the attribute, or -1 if it does not appear in the list.

getType

CharArray getType(CharSequence uri,
                CharSequence localName)

Looks up an attribute's type by Namespace name (convenience method). This method returns the type of the attribute whose uri/localName have the same character content as the specified uri/localName.

Parameters:

uri - the Namespace URI, or an empty string if the name has no Namespace URI.

localName - the local name of the attribute.

Returns:

the attribute type as a string, or null if the attribute is not in the list or if Namespace processing is not being performed.

getType

CharArray getType(CharSequence qName)

Looks up an attribute's type by XML 1.0 qualified name. This method returns the type of the attribute whose qName has the same character content as the specified qName.

Parameters:

qName - The XML 1.0 qualified name.

Returns:

the attribute type as a string, or null if the attribute is not in the list or if qualified names are not available.

getValue

CharArray getValue(CharSequence uri,
                 CharSequence localName)

Looks up an attribute's value by Namespace name (convenience method). This method returns the value of the attribute whose uri/localName have the same character content as the specified uri/localName.

Parameters:

uri - the Namespace URI, or the empty string if the name has no Namespace URI.

localName - the local name of the attribute.

Returns:

the attribute value as a character sequence, or null if the attribute is not in the list.

getValue

CharArray getValue(CharSequence qName)

Looks up an attribute's value by XML 1.0 qualified name (convenience method). This method returns the value of the attribute whose qName has the same character content as the specified qName.

Parameters:

qName - The XML 1.0 qualified name.

Returns:

the attribute value as a character sequence, or null if the attribute is not in the list or if qualified names are not available.
