org.apache.flex.compiler.tree.as.ISwitchNode

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.

        ISwitchNode node = (ISwitchNode) getNode(
                "switch(i){case 1: { break; }}", ISwitchNode.class);
        visitor.visitSwitch(node);
        // TODO case BLOCK statements are SYNTHESIZED so they will never show BRACES
        // without extra help from us
        assertOut("switch (i) {\n\tcase 1:\n\t\tbreak;\n}");

    }


    @Test
    public void testVisitSwitch_2()
    {
        ISwitchNode node = (ISwitchNode) getNode(
                "switch(i){case 1: break; default: return;}", ISwitchNode.class);
        visitor.visitSwitch(node);
        assertOut("switch (i) {\n\tcase 1:\n\t\tbreak;\n\tdefault:\n\t\treturn;\n}");
