Examples of org.eclipse.jdt.core.dom.SingleVariableDeclaration

org.eclipse.jdt.core.dom.SingleVariableDeclaration
Single variable declaration AST node type. Single variable declaration nodes are used in a limited number of places, including formal parameter lists and catch clauses. They are not used for field declarations and regular variable declaration statements. For JLS2:
```
 SingleVariableDeclaration: { Modifier } Type Identifier { [] } [ = Expression ] 
```
For JLS3, the modifier flags were replaced by a list of modifier nodes (intermixed with annotations), and the variable arity indicator was added:
```
 SingleVariableDeclaration: { ExtendedModifier } Type [ ... ] Identifier { [] } [ = Expression ] 
```
