Interface ISwitchNode

All Superinterfaces:

IASNode, IConditionalNode, ISourceLocation, IStatementNode

All Known Implementing Classes:

SwitchNode

public interface ISwitchNode
extends IConditionalNode

An AST node representing a switch statement.

The shape of this node is:

 ISwitchNode
   IExpressionNode    <-- getConditionalExpressionNode()
   IBlockNode         <-- getStatementContentsNode()
     IConditionalNode <-- getCaseNodes()[0]
     IConditionalNode <-- getCaseNodes()[1]
     ...
     ITerminalNode    <-- getDefaultNode()
 

For example,

 switch (i)
 {
     case 1:
         return a;
     case 3:
         return b;
     default:
         return c;
 

is represented as

 ISwitchNode
   IIdentifierNode "i"
   IBlockNode
     IConditionalNode
       INumericLiteralNode 1
       IBlockNode
         IReturnNode
           IIdentifierNode "a"
     IConditionalNode
       INumericLiteralNode 2
         IBlockNode
           IReturnNode
             IIdentifierNode "b"
     ITerminalNode
       IBlockNode
         IReturnNode
           IIdentifierNode "c"
 

An implicit IBlockNode is created for each case and default clause that doesn't have curly braces.
