User-defined logical structures

En eclipse ya se pueden definir formas más adecuadas para mostrar en depuración los valores de las variables. Especialmente útil para colections, puede ampliarse a cualquier clase que construyamos.

User defined logical structures

The Java debugger now lets you control what gets shown in the variables view for different types of objects. For example, collections can be displayed as a simple array of values, instead of the gory details on how that particular collection object is implemented.

This is done from the Java > Debug> Logical Structures preference page, where you associate with a specific class or interface either a single expression (for example, this.toArray()) or a series of named expressions. When the object is to be shown in the variables view, the expressions are evaluated to produce the values to display.
