Interface AttributeCollection

All Known Implementing Classes:

AttributeCollectionImpl, TinyAttributeCollection

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

getLength

int getLength()

Return the number of attributes in the list.

Returns:

The number of attributes in the list.

getNodeName

NodeName getNodeName(int index)

Get the node name of an attribute (by position)

Parameters:

index - The position of the attribute in the list

Returns:

The node name of the attribute, or null if there is no attribute in that position

getNameCode

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.

getTypeAnnotation

SimpleType 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

getLocationId

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

getSystemId

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

getLineNumber

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

getProperties

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

getPrefix

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.

getQName

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.

getLocalName

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.

getURI

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.

getIndex

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

int getIndexByFingerprint(int fingerprint)

Get the index, given the fingerprint

getValueByFingerprint

String getValueByFingerprint(int fingerprint)

Get the attribute value using its fingerprint

getValue

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

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.

isId

boolean isId(int index)

Determine whether a given attribute has the is-ID property set

isIdref

boolean isIdref(int index)

Determine whether a given attribute has the is-idref property set
