      public interface LogicalStructure

  SmartGWT classes implementing

      LogicalStructure

  allow their JavaScript state to be viewed in an Eclipse Java debugging environment, using Eclipse's logical structure facility. To use this:
  - In Eclipse, open the Preferences dialog, and navigate to the "Logical Structures" page (Java->Debug->Logical Structures). Add two new entries:
    1. Qualified type name:

           com.smartgwt.client.core.LogicalStructure

       Description: SmartGWT LogicalStructure
       Applies to subtypes: Checked
       Structure type: Single value
       Code:

           this.initNativeObject(); return this;

    2. Qualified type name:

           com.smartgwt.client.core.NativeObject

       Description: SmartGWT NativeObject
       Applies to subtypes: Checked
       Structure type: Single value
       Code:

           return this.o.getLogicalStructure();

  - Debug your SmartGWT application in Eclipse as you normally would.
  - When viewing variables structurally (e.g., in the "Variables" or "Expressions" view, or when hovering over a variable), objects implementing LogicalStructure will have a

        nativeObject

    field, the contents of which are described below:
    - The

          scClassName

      field contains the underlying SmartClient class name for the object.
    - The documented attributes for the SmartClient class, and its superclasses, are displayed as separate fields.

    -     nativeObject

      field values are always cast to Strings in JavaScript, unless the field is a class which implements

          LogicalStructure

      , or is an array thereof (e.g.

          Layout.members

      ). In that case, the value of the field is the underlying SmartGWT object, which in turn has its own

          nativeObject

      field, etc.
    - The

          logicalStructureErrors

      field is a string describing all of the runtime errors encountered when displaying other

          nativeObject

      fields.
    - A

          null

      value for a

          nativeObject

      field may indicate any of the following:
      - The underlying JavaScript attribute is undefined.
      - The underlying JavaScript attribute is defined, but set to

            null

        .
      - An error occurred while attempting to read the attribute, which would be documented in the value of

            logicalStructureErrors

        .

  For more information on the JavaScript state of SmartGWT objects, consult the SmartClient documentation.
