Adds a new child tree with the given name and primary type name. This method is a shortcut for calling Tree.addChild(String) and Tree.setProperty(String, Object, org.apache.jackrabbit.oak.api.Type) where the property name is JcrConstants.JCR_PRIMARYTYPE. Note, that this method in addition verifies if the created tree exists and is accessible in order to avoid IllegalStateException upon subsequent modification of the new child.

Parameters:

childName - The Oak name of the child item.

primaryTypeName - The Oak name of the primary node type.

Returns:

The new child tree with the specified name and primary type.

Throws:

AccessDeniedException - If the child does not exist after creation.

Combination of Tree.getChild(String) and adding a child including its jcr:primaryType property (i.e. Tree.addChild(String) and Tree.setProperty(PropertyState)) in case no tree exists with the specified name.

Parameters:
