getMapping

public org.w3c.dom.Attr getMapping(java.lang.String prefix)

Gets the attribute node that defines the binding for the prefix.

Parameters:

prefix - the prefix to obtain the attribute.

Returns:

null if there is no need to render the prefix. Otherwise the node of definition.

getMappingWithoutRendered

public org.w3c.dom.Attr getMappingWithoutRendered(java.lang.String prefix)

Gets a definition without mark it as render. For render in exclusive c14n the namespaces in the include prefixes.

Parameters:

prefix - The prefix whose definition is neaded.

Returns:

the attr to render, null if there is no need to render

addMapping

public boolean addMapping(java.lang.String prefix,
                          java.lang.String uri,
                          org.w3c.dom.Attr n)

Adds the mapping for a prefix.

Parameters:

prefix - the prefix of definition

uri - the Uri of the definition

n - the attribute that have the definition

Returns:

true if there is already defined.

addMappingAndRender

public org.w3c.dom.Node addMappingAndRender(java.lang.String prefix,
                                            java.lang.String uri,
                                            org.w3c.dom.Attr n)

Adds a definition and mark it as render. For inclusive c14n.

Parameters:

prefix - the prefix of definition

uri - the Uri of the definition

n - the attribute that have the definition

Returns:

the attr to render, null if there is no need to render
