org.apache.flex.compiler.tree.as.IIfNode

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
