With FDT 5, the team has added powerful refactoring to your workflow. These refactorings have been integrated into our Quick Assist workflow, so you won't be slowed down at all - in fact you'll see how quickly you can restructure your code.

Extract Method

EM 001.png Perhaps the most powerful, and fun, refactoring is Extract Method.

This allows you to select a block of code and convert it to a method. FDT automatically infers the method arguments and return types. This is useful when a method is too big and you want to subdivide blocks of it into different methods or if you are executing a computation several times in your code.

The default keystroke for this is CMD+1.

Extract Local Variable

ELV 001.png The Extract Local Variable refactoring takes an expression that is being used directly and assigns it to a local variable first. This variable is then used where the expression used to be.

To use it press Ctrl+1 and select assign statement to a local variable.

Extract Contant

EC 001.png Extract Contant enables developers to quickly assign strings, colors, object literals and numbers to a static value. This makes renaming ( refactoring ) and changing these values much easier, increases performance and improves readability.

The default binding is CMD+1.

Convert Local Variable to Field Variable

This refactoring takes a local variable and converts it to a private field of the class. After invoked, FDT will create a statement at the top of your class and refactor all references so they reference the field declaration.

This refactoring is available via CMD+1

Split Local Variable Declaration

Split Local Variable Declaration.png This refactoring allows you to split a variable (with initialization) into two separate statements: a variable declaration and a variable initialization.

Like all Quick Assists, this invoked by pressing CMD+1.
