org.apache.flex.compiler.tree.as.IForLoopNode

An AST node representing a for, for-in, or for-each-in statement.

The shape of this node is

 IForLoopNode IContainerNode <-- getConditionalsContainerNode() IBlockNode     <-- getStatementContentsNode()

In the case of a regular for statement, the container node contains the three control expressions. For example,

 for (i = 0; i < n; i++) { ... }

is represented as

 IForLoopNode "for" IContainerNode IBinaryOperatorNode "=" IIdentifierNode "i" INumericalLiteralNode 0 IBinaryOperatorNode "<" IIdentifierNode "i" IIdentifierNode "n" IUnaryOperatorNode "++" IIdentifierNode "i" IBlockNode ...

In the case of a for-in, or for-each-in statement, the container node contains a single binary operator node for the in operator. For example,

 for (p in o) { ... }

is represented as

 IForLoopNode "for" IContainerNode IBinaryOperatorNode "in" IIdentifierNode "p" IIdentifierNode "o" IBlockNode ...
