Interface AttributeCollection

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.

Method Detail

getIndex

public int getIndex(String uri, String localname)
Get the index of an attribute (by name).

Parameters: uri The namespace uri of the attribute. localname The local name of the attribute.

Returns: The index position of the attribute

getIndexByFingerprint

public int getIndexByFingerprint(int fingerprint)
Get the index, given the fingerprint

getLength

public int getLength()
Return the number of attributes in the list.

Returns: The number of attributes in the list.

getLineNumber

public 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

getLocalName

public String getLocalName(int index)
Get the local name of an attribute (by position).

Parameters: index The position of the attribute in the list.

Returns: The local name of the attribute as a string, or null if there is no attribute at that position.

getLocationId

public 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

getNameCode

public 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.

getPrefix

public String getPrefix(int index)
Get the prefix of the name of an attribute (by position).

Parameters: index The position of the attribute in the list.

Returns: The prefix of the attribute name as a string, or null if there is no attribute at that position. Returns "" for an attribute that has no prefix.

getProperties

public 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 {DEFAULTED_ATTRIBUTE, which indicates an attribute that was added to an element as a result of schema validation.

getQName

public String getQName(int index)
Get the lexical QName of an attribute (by position).

Parameters: index The position of the attribute in the list.

Returns: The lexical QName of the attribute as a string, or null if there is no attribute at that position.

getSystemId

public 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

getTypeAnnotation

public 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 IS_DTD_TYPE represents a DTD-derived type.

getURI

public String getURI(int index)
Get the namespace URI of an attribute (by position).

Parameters: index The position of the attribute in the list.

Returns: The local name of the attribute as a string, or null if there is no attribute at that position.

getValue

public String getValue(String uri, String localname)
Get the value of an attribute (by name).

Parameters: uri The namespace uri of the attribute. localname The local name of the attribute.

Returns: The value of the attribute

getValue

public String getValue(int index)
Get the value of an attribute (by position).

Parameters: index The position of the attribute in the list.

Returns: The attribute value as a string, or null if there is no attribute at that position.

getValueByFingerprint

public String getValueByFingerprint(int fingerprint)
Get the attribute value using its fingerprint

isId

public boolean isId(int index)
Determine whether a given attribute has the is-ID property set

isIdref

public boolean isIdref(int index)
Determine whether a given attribute has the is-idref property set
