About groupJS

GroupJS is a javascript module for structuring javascript modules into a "group". Simply put, we want a group as a component which is composited by javascript modules which can be overriden.

For example, group A includes module A1, A2 and A3. A1, A2 and A3 interact internally. You can create module A11 replace A1 in group A.

Group A can be "inherited". E.g. you create group AA with the same function as group A. group AA can extend its method and attributes without interfering with group A.

Usages

Object Inheritance

• obj.create(<object id>) - Create a new object. should be identifier of an object.

  var newObj = Grp.obj.create('newObj');
  var newObj_1 = newObj.create('newObj_1');

• obj.extend( obj1 [, obj2, ......] ) - extend object's attributes. If attribute exists, it will be overriden.

  var newObj = Grp.obj.create('newObj');
  newObj.extend({
      newAttribute: function() {
      alert('this is a new attribute');
      },
  });

• obj.reservedAttr - Array of string to reserved attributes or methods names for this module.

• obj.init() - initialize local variable

Group

• group.create(<group id>) - create a new group

• group.join(<member or sub-Group>[, <member2 or sub-Group2>...]) - join a memeber into this group. If member name exists, the member will be overriden.

  //create a member
  var newObj = Grp.obj.create('newObj');
  newObj.extend({
      newAttribute: function(opt) {
          alert('this is a new attribute for ' + opt._id||'');
      },
  });
  
  //create a group
  var newGrp = Grp.group.create('newGrp');
  newGrp.join(newObj);
  newGrp.extend({
      promptAlert: function(opt) {
          this.call('newObj', 'newAttribute', opt );
      },
  });
  
  var grpTest = newGrp.create('grpTest');
  var opt = { name: 'grpTest_Name' };
  grpTest.promptAlert(opt);

• group.call() - call its own member command. If inherited, the member will still be called based on parents list. return its result or the last call's result.

  • For group level, this.call(<member or memberID>, <methodName>, opt)
  • For member level, this.group.call(<member or memberID>, <methodName>, opt)

• group.upCall() - call its own member command or find in upper group's member command. First hit will be return.!!!

  • For group level, this.upCall(<memberName>, <methodName>, opt)
  • For member level, this.group.upCall(<memberName>, <methodName>, opt)

• group.downCall() - call its own member command or find in sub group's member command. First hit will be return.!!!

  • For group level, this.downCall(<memberName>, <methodName>, opt)
  • For member level, this.group.downCall(<memberName>, <methodName>, opt)

• group.group - for member, it refers to its group; for group, refers to its parent group.

• group.members() - show a map of this group's members.

• group.getMember(memberName[, memberMap]) - get a member by name.

• group.override(newMember[, memberMap]) - To be overridden the member with the same _id. Note: Do not use it
