All Known Implementing Classes:
FieldDeclaration, VariableDeclarationExpr
public interface NodeWithVariables<N extends Node>
A node which has a list of variables.

  • Method Details

    • getVariables

      NodeList<VariableDeclarator> getVariables()

    • setVariables

      N setVariables​(NodeList<VariableDeclarator> variables)

    • getVariable

      default VariableDeclarator getVariable​(int i)

    • setVariable

      default N setVariable​(int i, VariableDeclarator variableDeclarator)

    • addVariable

      default N addVariable​(VariableDeclarator variableDeclarator)

    • getCommonType

      default Type getCommonType()
      Returns the type that is shared between all variables. This is a shortcut for when you are certain that all variables share one type. What makes this difficult is arrays, and being able to set the type.
      For int a; this is int.
      For int a,b,c,d; this is also int.
      For int a,b[],c; this is an assertion error since b is an int[], not an int.
      For int a,b;, then doing setType(String) on b, this is an assertion error. It is also a situation that you don't really want.

    • getElementType

      default Type getElementType()
      Returns the element type.
      For int a; this is int.
      For int a,b,c,d; this is also int.
      For int a,b[],c; this is also int. Note: no mention of b being an array.
      For int a,b;, then doing setType(String) on b, then calling getElementType(). This is an assertion error. It is also a situation that you don't really want.

    • setAllTypes

      default N setAllTypes​(Type newType)
      Sets the type of all variables. Erases any existing type. This is a shortcut for setting a type on all variable declarators separately.

    • getMaximumCommonType

      default Optional<Type> getMaximumCommonType()
      Returns the type that maximum shared type between all variables. The minimum common type does never include annotations on the array level.


      For int a; this is int.
      For int a,b,c,d; this is also int.
      For int a,b[],c; this is also int.
      For int[] a[][],b[],c[][]; this is int[][].

    • calculateMaximumCommonType

      static Optional<Type> calculateMaximumCommonType​(List<Type> types)
