Grouping Functions

See also: Expression Language and Function Index

The expression language is largely used to evaluate one file at a time. The grammar implies that something like Field(Artist) should get the Artist value for the current file being evaluated. Grouping Functions are a special class of functions that operate on a group of files, instead of on individual files. A simple example would be a function to count the number of artists in the current group.

Grouping Functions may only be used in relevant areas (most notably Categories and the Tag Action Window) where Media Center displays groups of files, and not to individual file listings (such as an expression column in a File Details View).
