Detailed Description

Nested tree of parameters.

Parameters are retrieved using a path. The value of parameters can be primitive types like string or floating point as well as some basic game engine classes like point or vectors and arrays thereof. Parameter trees can be loaded from and written to XML files. This class is best used to load parameters from XML files without the need to write specific XML loaders and complex parameter storing classes. A typical use case is prototyping, storing small lists of parameters or storing information with structure not known at build time.

This class itself does not enforce a specific path separator. The LoadParameterTree class thought uses '/' as path separator. It is encouraged to use '/' as path separator.

(

)

Create parameter tree.

new() [2/2]

ParameterTree Dragengine.Utils.ParameterTree.new

(

ParameterTree

tree

)

void Dragengine.Utils.ParameterTree.removeAll

(

)

Remove all values.
