Package facets.util.treecode Description

Construction and referencing of objects defined by DataNodes.

Tree coding

Tree coding enables the construction of arbitrary Java objects defined by DataNode sources where:

• the type() of the source specifies an instantiable Java type
• the title() provides text that can identify either the tree-coded object itself or one that it must reference
• the contents() define construction parameters which may include other tree-coded objects defined by children()

A graph of TreeCodeds can therefore be naturally edited in DataNode-aware tree viewers.

Since DataNodes can be represented in XML via XmlRoot, TreeCoded graphs can also be edited structurally in any XML editor and textually in any text editor (possibly for preference where complex text substitutions are required during dialect design).

Core types

This package provides the following types providing for tree-coding of Java objects.

TreeCoded

Wraps a source DataNode containing its code and data, and has a Label allowing it to be referenced by or reference other TreeCodeds.

TreeCodeType

Constructs a TreeCoded instance as specified by a coding DataNode, supplying a TreeCodeTypes (and where relevant a TreeCodeContext) to allow construction of TreeCoded contents.

TreeCodeContext

Provides for referencing of TreeCodeds by (non-empty) Labels.

TreeCodeTypes

Defines the TreeCodeTypes available to a TreeCoded framework.
