<p>src/pmc/lexinfo.pmc - LexInfo PMC</p>
<h1><a name="DESCRIPTION"
>DESCRIPTION</a></h1>
<p>These are the vtable functions for the lexinfo PMC.</p>
<h2><a name="Functions"
>Functions</a></h2>
<dl>
<dt><a name="void_class_init()"
><b><code>void class_init()</b></code></a></dt>
Manipulate vtable->flags so that constant PMCs are created.
If your inherited LexInfo is not so constant,
then don't do that and provide a mark() method and set the custom_mark flag.
<dt><a name="init_pmc(PMC_*sub)"
><b><code>init_pmc(PMC *sub)</b></code></a></dt>
Initialize the LexInfo PMC and remember the associate subroutine.
<dt><a name="void_declare_lex_preg(STRING_*name,_INTVAL_preg)"
><b><code>void declare_lex_preg(STRING *name, INTVAL preg)</b></code></a></dt>
Declare a lexical variable that is an alias for a PMC register.
The PIR compiler calls this method in response to a ".lex STRING,
PREG" directive.
<dt><a name="INTVAL_elements()"
><b><code>INTVAL elements()</b></code></a></dt>
Returns the number of elements in the LexInfo hash.
<dt><a name="PMC_*inspect_str(STRING_*what)"
><b><code>PMC *inspect_str(STRING *what)</b></code></a></dt>
Introspects this LexInfo structure.
The only valid introspection key is <code>symbols</code>,
which gets an array of the names of the symbols in this lexpad.
<dt><a name="void_visit(visit_info_*info)"
><b><code>void visit(visit_info *info)</b></code></a></dt>
<dt><a name="void_freeze(visit_info_*info)"
><b><code>void freeze(visit_info *info)</b></code></a></dt>
<dt><a name="void_thaw(visit_info_*info)"
><b><code>void thaw(visit_info *info)</b></code></a></dt>
Freeze/thaw interface used during freeze/thaw of the Sub PMC.
The implementation of the Hash PMC is called.</dl>
