Constructor Detail

SpaceStrippedDocument

public SpaceStrippedDocument(DocumentInfo doc,
                     SpaceStrippingRule strippingRule)

Create a space-stripped view of a document

Parameters:

doc - the underlying document

strippingRule - an object that contains the rules defining which whitespace text nodes are to be absent from the view

Method Detail

wrap

public SpaceStrippedNode wrap(NodeInfo node)

Create a wrapped node within this document

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

getStrippingRule

public SpaceStrippingRule getStrippingRule()

Get the document's strippingRule

getConfiguration

public Configuration getConfiguration()

Get the configuration previously set using setConfiguration

Specified by:

getConfiguration in interface NodeInfo

Overrides:

getConfiguration in class AbstractVirtualNode

Returns:

the Configuration

getNamePool

public NamePool getNamePool()

Get the name pool used for the names in this document

Specified by:

getNamePool in interface NodeInfo

Overrides:

getNamePool in class AbstractVirtualNode

Returns:

the NamePool

getDocumentNumber

public long getDocumentNumber()

Get the unique document number

Specified by:

getDocumentNumber in interface NodeInfo

Overrides:

getDocumentNumber in class AbstractVirtualNode

Returns:

the document number of the document containing this node

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 value, or null if there is none.

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 (as an absolute URI if possible), the second holding the public ID if there is one, or null if not. If the entity does not exist, the method returns null. Applications should be written on the assumption that this array may be extended in the future to provide additional information.

containsPreserveSpace

public boolean containsPreserveSpace()

Ask whether the stripped document contains any xml:space="preserve" attributes.

Returns:

true if any element in the document has an xml:space attribute with the value "preserve"

containsAssertions

public boolean containsAssertions()

Ask whether the stripped document contain any nodes annotated with types that carry assertions

Returns:

true if any element in the document has a type that has an assertion

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.
