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

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:
- every component of A satisfies at least one component of B and
- 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".
