hasMoreChildren

public boolean hasMoreChildren()

Description copied from interface: HierarchicalStreamReader

Does the node have any more children remaining that have not yet been read?

Specified by:

hasMoreChildren in interface HierarchicalStreamReader

moveUp

public void moveUp()

Description copied from interface: HierarchicalStreamReader

Select the parent node as current node.

Specified by:

moveUp in interface HierarchicalStreamReader

moveDown

public void moveDown()

Description copied from interface: HierarchicalStreamReader

Select the current child as current node. A call to this function must be balanced with a call to HierarchicalStreamReader.moveUp().

Specified by:

moveDown in interface HierarchicalStreamReader

getAttributeNames

public Iterator getAttributeNames()

Description copied from interface: HierarchicalStreamReader

Iterator with the names of the attributes.

Note, the iterator is only valid as long as the internal state of the underlying parser is still at the start of the current element. The behavior is undefined if the parser moved on.

Specified by:

getAttributeNames in interface HierarchicalStreamReader

appendErrors

public void appendErrors(ErrorWriter errorWriter)

Description copied from interface: HierarchicalStreamReader

If any errors are detected, allow the reader to add any additional information that can aid debugging (such as line numbers, XPath expressions, etc).

Specified by:

appendErrors in interface ErrorReporter

Specified by:

appendErrors in interface HierarchicalStreamReader

Parameters:

errorWriter - the error writer

getCurrent

public Object getCurrent()

Description copied from interface: DocumentReader

Retrieve the current processed node of the DOM.

Specified by:

getCurrent in interface DocumentReader

Returns:

the current node

close

public void close()

Description copied from interface: HierarchicalStreamReader

Close the reader, if necessary.

Specified by:

close in interface HierarchicalStreamReader
