OCL Precedence rules

The precedence order for the operations, starting with the highest precedence, in OCL is:

  • dot and arrow operations: “.” and “->”
  • unary “not” and unary minus
  • “*” and “/”
  • “+” and binary “-”
  • “if-then-else-endif”
  • “and”, “or”, and “xor”
  • “implies”
  • “<“, “>”, “<=”, “>=”
  • “=”, “<>”

Parentheses “(“ and “)” can be used to change precedence.

Note! This is not exactly according to the current OCL standard. In standard OCL, “and”, “or”, “xor” and “implies” have lower precedence than “<“, “>”, “<=”, “>=”, “=”, and “<>”
