Interface IIfNode

All Superinterfaces:

IASNode, IConditionalNode, ISourceLocation, IStatementNode

All Known Implementing Classes:

IfNode

public interface IIfNode
extends IConditionalNode

An AST node representing an if statement.

The shape of this node is

 IIfNode
   IConditionalNode <-- ???
   IConditionalNode <-- getElseIfNodes()[0]
   IConditionalNode <-- getElseIfNodes()[1]
   ...
   ITerminalNode    <-- getElseNode()
 

Example 1:

 if (a > b)
     return 1;
 

is represented as

 IIfNode
   IConditionalNode
     IBinaryOperatorNode ">"
       IIdentifierNode "a"
       IIdentifierNode "b"
     IBlockNode
       IReturnNode
         INumericLiteralNode 1
 

Example 2:

 if (a > b)
     return 1;
 else
     return 2;
 

is represented as

 IIfNode
   IConditionalNode
     IBinaryOperatorNode ">"
       IIdentifierNode "a"
       IIdentifierNode "b"
     IBlockNode
       IReturnNode
         INumericLiteralNode 1
   ITerminalNode "else"
     IBlockNode
       IReturnNode
         INumericLiteralNode 2
 

Example 3:

 if (a > b)
     return 1;
 else if (a < b)
     return -1;
 else
     return 0;
 

is represented as

 IIfNode
   IConditionalNode
     IBinaryOperatorNode ">"
       IIdentifierNode "a"
       IIdentifierNode "b"
     IBlockNode
       IReturnNode
         INumericLiteralNode 1
   IConditionalNode
     IBinaryOperatorNode "<"
       IIdentifierNode "a"
       IIdentifierNode "b"
     IBlockNode
       IReturnNode
         INumericLiteralNode -1
   ITerminalNode "else"
     IBlockNode
       IReturnNode
         INumericLiteralNode 0
