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". |
