I have a task in eclipse to enable the functionality in which when we type in a particular word or character a pre defined word/character automatically appears without having to use ctrl+space.

Eg. if i write "begin" then "end" should appear automatically.
just like opening and closing brackets,etc

the class full name is "org.eclipse.xtext.ui.editor.autoedit.DefaultAutoEditStrategyProvider" and it is contained in org.eclipse.xtext.ui
so it should be accessible from yourdsl.ui plugin.

where did you search for the class?

Actually I am a beginner in Xtext.. and I was doing some hands-on, So I created this following:

grammar org.xtext.example.mydsl.MyDsl with org.eclipse.xtext.common.Terminals

generate myDsl "http://www.xtext.org/example/mydsl/MyDsl"

Model:
greetings=Greeting;

Greeting:

rule1|rule2
;
rule1:
start='begin' text=STRING stop= 'end'
;
rule2:
start='begin' stop='end'
;

I dont even know if this grammar is write according to my needs.

Did you have a look at the domain model example. It contains an edit strategy

well you code is java code and the module is written in xtend so you have to transform it to a xtend method

def Class<? extend InsertBaseClassHere> bindInsertBaseClassHere() {
InsertCustomClassHere
}
