Debugger. Data Type Renderers

GoLand allows you to specify how different objects are displayed in the debugger on a class-by-class basis. You can assign the expressions to be displayed rather than rely on the object's String representation.

For example, if an object represents a user, you may want it to be represented by login names; or, for a cache entry object, its content may be appropriate. GoLand refers to these as type renderers.

All object types are supported (including primitive types and arrays).

If no rendering scheme is defined, this dialog does not show any controls. To start working with renderers, click .

Item	Description
Renderer name	The name of the renderer. This name is used for managing renderers and doesn't affect how actual data is displayed.
Apply renderer to objects of type (fully-qualified name)	The object type to which this renderer applies. Enter the fully qualified name of the class.
When rendering a node	This option determines how an object itself is displayed: Use default renderer: displays the object as it would be displayed without this renderer. This is useful if you want to only customize the way the object's contents are displayed. Use following expression: lets you use the return value of some expression for displaying the object. All method calls and member variable access are relative to the rendered instance.
When expanding a node	This option determines how the contents of an object are displayed when it is expanded. Use default renderer: displays the node children as they would be displayed without this renderer. This is useful if you want to only customize the way the object itself is displayed. Use list of expressions: allows you to specify multiple expressions each providing its own representation of the object's children.
Append default children	Controls whether the fields of the object (that would be normally displayed when no renderer is specified) should appear along with the expression results. This option is only available with Use list of expressions.
