Global Variables, Functions, and Expression Operators
Visualforce pages use the same expression language as formulas—that is, anything inside {! } is evaluated as an expression that can access values from records that are currently in context.
This appendix provides an overview of the variables, functions, and operators that can be used in Visualforce expressions.
-
Use global variables to reference general information about the current user and your organization on a page.
-
Use functions to transform data from records, perform calculations, or to provide values for Visualforce attributes.
-
Use operators to join expressions together to create compound expressions.
