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.
