How to refer to current node name in “execute at begin node”

Hi I'm wondering how can I reference to current node name in execute at begin node property.

\node[execute at begin node = \command_which_uses_node_name_to_to_do_soething_draw_uml_component_symbol] (){Node-name};

Could you give a MWE. –  xfoo Dec 27 '12 at 19:56
@Meter: That's not an MWE. An MWE is a complete minimal example document, which saves people the work of having to come up with a test document themselves (because that part of answering questions is pretty boring). –  Jake Dec 27 '12 at 20:17

The node name is stored in \tikz@fig@name at the time the code in execute at begin node is executed.

Here's an MWE, which prints > \tikz@fig@name=macro: ->myname. into the .log file:

\documentclass{article}
\usepackage{tikz}

\begin{document}

\makeatletter
\tikzset{
teststyle/.style={
execute at begin node=\show\tikz@fig@name
}
}
\makeatother

\begin{tikzpicture}
\node (myname) [teststyle] {Text};
\end{tikzpicture}

\end{document}

Note: even if we know its future name, the node does not yet exist at that time (execute at begin node). –  Paul Gaborit Dec 28 '12 at 8:32
