Constructor Detail

VirtualDocumentCopy

public VirtualDocumentCopy(DocumentInfo base)

Method Detail

isTyped

public boolean isTyped()

Ask whether the document contains any nodes whose type annotation is anything other than UNTYPED

Specified by:

isTyped in interface DocumentInfo

Returns:

true if the document contains elements whose type is other than UNTYPED

selectID

public NodeInfo selectID(String id,
                boolean getParent)

Get the element with a given ID, if any

Specified by:

selectID in interface DocumentInfo

Parameters:

id - the required ID value

getParent -

Returns:

the element with the given ID, or null if there is no such ID present (or if the parser has not notified attributes as being of type ID)

getUnparsedEntityNames

public Iterator<String> getUnparsedEntityNames()

Get the list of unparsed entities defined in this document

Specified by:

getUnparsedEntityNames in interface DocumentInfo

Returns:

an Iterator, whose items are of type String, containing the names of all unparsed entities defined in this document. If there are no unparsed entities or if the information is not available then an empty iterator is returned

getUnparsedEntity

public String[] getUnparsedEntity(String name)

Get the unparsed entity with a given name

Specified by:

getUnparsedEntity in interface DocumentInfo

Parameters:

name - the name of the entity

Returns:

if the entity exists, return an array of two Strings, the first holding the system ID of the entity, the second holding the public ID if there is one, or null if not. If the entity does not exist, return null.

setUserData

public void setUserData(String key,
               Object value)

Set user data on the document node. The user data can be retrieved subsequently using getUserData(java.lang.String)

Specified by:

setUserData in interface DocumentInfo

Parameters:

key - A string giving the name of the property to be set. Clients are responsible for choosing a key that is likely to be unique. Must not be null. Keys used internally by Saxon are prefixed "saxon:".

value - The value to be set for the property. May be null, which effectively removes the existing value for the property.

getUserData

public Object getUserData(String key)

Get user data held in the document node. This retrieves properties previously set using setUserData(java.lang.String, java.lang.Object)

Specified by:

getUserData in interface DocumentInfo

Parameters:

key - A string giving the name of the property to be retrieved.

Returns:

the value of the property, or null if the property has not been defined.
