Method Details

merge

MergeableNode merge(MergeableNode node)
             throws ConfigException

Returns new instance mergeable node of same type of original one that merges also with specified node.

Parameters:

node - node to be used to merge with

Returns:

new instance of mergeable node that combines original node with specified one

Throws:

ConfigException - in case it if not possible to merge original node with new one.

hasValue

boolean hasValue()

Each node may have a direct value, and in addition may be an object node or a list node. This method returns true for any node with direct value.
