15.2.6 Restricting displayed signatures by class

The Method Signatures dialog was introducted in Signatures button. You can display this dialog by clicking Signatures... in the Generic Function Browser.

By default, the Method Signatures dialog displays the signatures of all methods defined on the generic function. When there are many methods, or when the distinction between different classes is not clear, this can be confusing.

To simplify the display, you can restrict the signatures displayed to a chosen class and its superclasses. To do this, enter the name of the chosen class into the Restricted Class box. You can click which allows you to select from a list of all class names which begin with the partial input you have entered. See Completion for detailed instructions. As with similar text input panes in the IDE, click to confirm your choice, to cancel the current setting.

Figure 15.4 Restricting the signatures by class

Once you have made a choice, only those signatures that contain the specified class or one of its superclasses are listed in the Signatures restricted to... panel of the dialog. This simplified display is useful when there are a large number of complicated signatures.

Be aware of the difference between this approach and the use of the Argument box in the Signatures panel. Restricting signatures confines the signatures offered in the dialog by means of the class of the signatures.

Click to display the signatures for all methods defined once again.
