示例1: return
Token *Command::arg(int idx)
{
for(Shard *it = first(); it; it = it->next())
{
if(idx--) continue;
it = it->first();
if(!it || it->type() != BLOCK) break;

}示例2: generateRule
/**
* An exception will be thrown if there is an error.
*/
void RuleSet::generateRule(Command *command)
{
Rule *rule;
Shard *it;
GemTest *terms;
// Create the rule object.
if(command->isName("format"))
{
rule = new FormatRule(((Block*)command->last()->first())->collect());
}
else
{
rule = new LengthRule;
}
terms = &rule->terms();
// Compile the terms (command -> shards -> blocks -> tokens).
for(it = command->first();

{
if(!it->first()) continue;
terms->addBefore(new GemTest((Token*)it->first()->first()));
}

{
// There must not be format rules with matching terms.
removeMatching(*terms, Rule::FORMAT);
add(rule);
}
else
{
add(rule);
Length *len = &((LengthRule*)rule)->length();
// Set the lengths that were given.
// Get last argument -> block -> first token.
len->init((Token*)command->last()->first()->first());
// Was this all for naught?
if(len->isClear()) delete remove(rule);
}
