org.apache.flex.compiler.tree.as.ITryNode

An AST node representing a try statement.

The shape of this node is:

 ITryNode  IBlockNode    <-- getStatementContentsNode() ICatchNode    <-- getCatchNode(0) ICatchNode    <-- getCatchNode(1) ... ITerminalNode <-- getFinallyNode()

For example,

 try { ... } catch (e:SomeError) { ... } catch (e:Error) { ... } finally { ... }

is represented as

 ITryNode IBlockNode ... ICatchNode IParameterNode IIdentifierNode "e" IIdentifierNode "Error" IBlockNode ... ICatchNode IParameterNode IIdentifierNode "e" IIdentifierNode "Error" IBlockNode ... ITerminalNode "finally" IBlockNode ...
