Constructor Details

TinyAttributeCollection

public TinyAttributeCollection(TinyTree tree,
                               int element)

Method Details

getIndex

public int getIndex(String uri,
                    String localname)
Get the index of an attribute (by name).
Specified by:
getIndex in interface AttributeCollection
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
Specified by:
getIndexByFingerprint in interface AttributeCollection

getLength

public int getLength()
Return the number of attributes in the list.
Specified by:
getLength in interface AttributeCollection
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.

Specified by:
getLineNumber in interface AttributeCollection
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).
Specified by:
getLocalName in interface AttributeCollection
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)
Specified by:
getLocationId in interface AttributeCollection
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).
Specified by:
getNameCode in interface AttributeCollection
Parameters:
index - The position of the attribute in the list.
Returns:
The display name of the attribute as a string, or null 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).
Specified by:
getPrefix in interface AttributeCollection
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)
Specified by:
getProperties in interface AttributeCollection
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.

getQName

public String getQName(int index)
Get the lexical QName of an attribute (by position).
Specified by:
getQName in interface AttributeCollection
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.

Specified by:
getSystemId in interface AttributeCollection
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).
Specified by:
getTypeAnnotation in interface AttributeCollection
Parameters:
index - The position of the attribute in the list.
Returns:
The type annotation of the attribute as the fingerprint of the type name. The bit NodeInfo.IS_DTD_TYPE represents a DTD-derived type.

getURI

public String getURI(int index)
Get the namespace URI of an attribute (by position).
Specified by:
getURI in interface AttributeCollection
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).
Specified by:
getValue in interface AttributeCollection
Parameters:
uri - The namespace uri of the attribute.
localname - The local name of the attribute.
Returns:
The index position of the attribute

getValue

public String getValue(int index)
Get the value of an attribute (by position).
Specified by:
getValue in interface AttributeCollection
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
Specified by:
getValueByFingerprint in interface AttributeCollection

isId

public boolean isId(int index)
Determine whether a given attribute has the is-ID property set
Specified by:
isId in interface AttributeCollection

isIdref

public boolean isIdref(int index)
Determine whether a given attribute has the is-idref property set
Specified by:
isIdref in interface AttributeCollection

setLocationProvider

public void setLocationProvider(LocationProvider provider)
Set the location provider. This must be set if the methods getSystemId() and getLineNumber() are to be used to get location information for an attribute.
