Method Detail

declareNamespace

public void declareNamespace(String nsURI,
                             String prefixHint)
                      throws IOException

Description copied from interface: XMLWriter

Hints that a namespace is going to be used in a sub-tree. Use this method to avoid namespaces that are used only in leaf-nodes of a tree being re-defined every time they are used. The XMLWriter will generally try to use the suggested prefix for this namespace, but there is no guarentee of this. In particular, if the namespace is already in use, the current prefix will still be used. Similarly if the suggested prefix has already been used for another namespace, a new one will be auto-generated.

Specified by:

declareNamespace in interface XMLWriter

Parameters:

nsURI - The namespace to declare

prefixHint - A suggested prefix-string for this namespace.

Throws:

IOException

writeIndent

protected void writeIndent()
