Get other field/column values within set method

Within Editor it is possible to create a custom field type. It has several functions like create, get and set. With set we can set the value of the field that will be edited. However within this set function we need the value of another field. With this.get('fieldname') we will always get an empty value. If we use the same code in the get function it will return the value of the given field. How can we achieve the same goal in the set function?
