示例1: aggregate
void BlockStatement::aggregate()
{
// Create scope.
scope = new SymbolTable(SymbolTable::getActiveScope());
// If this scope has a name, register that as
// a member of the containing scope.
if(name)
{
// Assumes this code will never get executed by the outermost block (before there is an active scope).
SymbolTable* outer = SymbolTable::getActiveScope();
PackageDefinition* package = new PackageDefinition(name->getValue(), scope);
// Shove the this package into the containing outer scope.
outer->put(package, getSourcePosition());
// Create a back-reference, so the scope knows it defines a new package,
// rather than just sharing a private subset of the outer scope's package.
scope->setPackage(package);
}
// Enter the created scope.
SymbolTable::enterScope(scope);
ListNode<Statement*>::ListType& list = statements->getList();
// First gather all constant definitions in this scope.
for(size_t i = 0; i < list.size(); i++)
{
Statement* statement = list[i];
if(statement->getStatementType() == Statement::CONSTANT_DECLARATION)
{
statement->aggregate();
}
}
// Next, if this is the main block, calculate the header.
if(handleHeader(list))
{
// Now, check out all the other statements.
for(size_t i = 0; i < list.size(); i++)
{
Statement* statement = list[i];
switch(statement->getStatementType())
{
// Skip already handled cases.
case Statement::CONSTANT_DECLARATION:
case Statement::HEADER:
break;
// Aggregate the rest.
default:
statement->aggregate();
break;
}
}
}
SymbolTable::exitScope();
}示例2: handleHeader
// Find and handle the header for the main block.
