 +=== localT(#id, #parent, #encl, #type, '​name',​ #​init) ​ ===
 +== ==
 +
 +Represents local variable declaration.
 +
 +== History ==
 +  * JTransformer 2.8: Added, up to 2.8.0 it was part of [[..:​old:​localdeft|localDefT]].
 +
 +
 +=== Arguments ===
 +== ==
 +**#id:** id\\ 
 +the unique ID assigned to this fact.
 +
 +**#​parent:​** id\\ 
 +ID of the parent node.
 +
 +**#encl:** [[methodt|methodT]],​ [[constructort|constructorT]],​ [[classinitializert|classInitializerT]]\\ ​
 +ID of the enclosing element.
 +
 +**#type:** [[typeinst]]\\ ​
 +the id of the type of the variable
 +
 +**'​name':​** atom\\ ​
 +variable name.
 + 
 +**#init:** [[plastexpression|expression]],​ null\\ ​
 +ID of the initializer of this variable declaration.
 + 
 +=== Sample Java Code ===
 +==  ==
 +<Code lang-java>​
 +void myFunction(){
 + int i = 0;//​corresponding code line to localT
 +}
