#deoptimize(*classes) ⇒ Object

#optimize(*args) ⇒ Object

Document-method optimize call-seq: optimize(*classes)

Use Oj rails optimized routines to encode the specified classes. This ignores the as_json() method on the class and uses an internal encoding instead. Passing in no classes indicates all should use the optimized version of encoding for all previously optimized classes. Passing in the Object class set a global switch that will then use the optimized behavior for all classes.

#optimized?(clas) ⇒ Boolean

  • clas [Class] Class to check

Returns:

  • (Boolean) —

    true if the class is being optimized for rails and false otherwise
