## ExpressionAstExpressionBuilder.findFunction property
|
|
|
|
Recursively searches expression for all ocurrences of the function, including in subexpressions.
|
|
|
|
Useful when performing migrations on a specific function, as you can iterate over the array of references and update all functions at once.
