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 namespace URI of the attribute as a string (empty string for an attribute in no namespace), 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.

    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.

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
