public abstract class UVariableDecl
extends UTree<com.sun.tools.javac.tree.JCTree.JCStatement>
implements com.sun.source.tree.VariableTree

A UTree representation of a local variable declaration.

A UVariableDecl can be unified with any variable declaration which has a matching type and initializer. Annotations and modifiers are preserved for the corresponding replacement, as well as the variable name. ULocalVarIdent instances are used to represent references to local variables.

As a result, we can modify variable declarations and initializations in target code while preserving variable names and other contextual information.
