Examples of liquibase.parser.core.ParsedNode

liquibase.parser.core.ParsedNode
Acts as a standard abstract syntax layer for changelogs defined in different formats. {@link liquibase.parser.ChangeLogParser} implementations and other classes that work with multiple formats can create objectsdirects or create instances of this class which can then be passed to the load() method of the object they want to configure. For example, {@link liquibase.change.Change#load(ParsedNode,liquibase.resource.ResourceAccessor)}.
ParsedNodes are a simple key/value structure with the following characteristics:
- Keys include a namespace as well as the node name
- There can be multiple children nodes with the same node namespace+name
- There is an unkeyed "value" object in addition to the children nodes
- The value node cannot be a ParsedNode. If you attempt to set value to be or contain a ParsedNode it will actually be set as a child
