Synopsis

getClassification [-satisfies string] string

getClassification is undoable, NOT queryable, and NOT editable.

Returns the classification string for a given node type.

Classification strings look like file pathnames ("shader/reflective" or "texture/2D", for example). Multiple classifications can be combined into a single compound classification string by joining the individual classifications with ':'. For example, the classification string "shader/reflective:texture/2D" means that the node is both a reflective shader and a 2D texture.

The classification string is used to determine how rendering nodes are categorized in various UI, such as the Create Render Node and HyperShade windows:

CategoryClassification String
2D Textures"texture/2d"
3D Textures"texture/3d"
Env Textures"texture/environment"
Surface Materials"shader/surface"
Volumetric Materials"shader/volume"
Displacement Materials"shader/displacement"
Lights"light"
General Utilities"utility/general"
Color Utilities"utility/color
Particle Utilities"utility/particle"
Image Planes"imageplane"
Glow"postprocess/opticalFX"

Return value

string[]Returns the classification strings for the given node type, or an empty array if the node type is not classified.

Flags

satisfies
Long name (short name) Argument types Properties
-satisfies(-sat) string create
Returns true if the given node type's classification satisfies the classification string which is passed with the flag.

A non-compound classification string A is said to satisfy a non-compound classification string B if A is a subclassification of B (for example, "shaders/reflective" satisfies "shaders").

A compound classification string A satisfies a compound classification string B iff:

  1. every component of A satisfies at least one component of B and
  2. every component of B is satisfied by at least one component of A

Hence, "shader/reflective/phong:texture" satisfies "shader:texture", but "shader/reflective/phong" does not satisfy "shader:texture".
