GWT Generators and OOPHM
Download as PPT, PDF1 like653 views
This document discusses GWT generators and outlines several key points: 1. Generators allow customizing GWT compilation by replacing or generating Java source code. They are defined in the module configuration file. 2. Creating a basic generator involves defining properties, checking conditions, and using GWT.create() to instantiate the generator class. 3. The module configuration syntax includes elements like <replace-with> and <generate-with> to specify which generators run under certain conditions.

- 2. Outline Generators Introduction to Generator Creating generator in short Defining module properties Syntax of module properties Demo of Generator &Debugging Generator Out of Process Hosted Mode Browser What is out of process Hosted Mode Browser
- 3. Introduction to Generators What is Generator? Whether I am using Generator indirectly any where? Why and where can I use these?
- 4. Creating Generator In Short Defining properties and rules in gwt.xml Create class using GWT.create(Type.class) Properties condition checking in module file (.gwt.xml) Substitution replace-with Generation generate-with
- 5. Defining module properties <define-property name= " widgetType " values= "basic,extended" /> <property-provider name= “widgetType" > <![CDATA[ try{ var tempVar = __gwt_getMetaProperty(" widgetType "); if (tempVar==null){ tempVar = "basic"; } return tempVar; } catch (e) { return "extended"; } ]]> </property-provider>
- 6. Syntax of module file (gwt.xml) <replace-with class= “com.barcamp.example.client.MyWidget”> <when-type-is class=“com.barcamp.example.client.TestWidget”/> <when-property-is name=“ widgetType ” value=“allahbaksh”/> </replace-with > <generate-with class= “com.barcamp.example.rebind.MyWidgetGenerator”> <when-type-is class=“com.barcamp.example.client.TestWidget”/> </ generate-with >
