示例1: CLRClosure
public CLRClosure(String title, Grammar grammar, IEnumerable<SLRProduction> productLALR)
: base(title, grammar)
{
SLRProductions = ((productLALR == default(CLRProduction[]))
? new List<SLRProduction>(new CLRProduction[] {})
: new List<SLRProduction>(productLALR));
var lastB = default(NonTerminal);
//A --> α.Bβ, a
for (var index = 0; index < Count; ++index)
{
var product = this[index] as CLRProduction;
if (default(Production) == product || product.DotPosition == product.Count) continue;
var entity = product.Product[product.DotPosition];
if (!(entity is NonTerminal)) continue;
var B = entity as NonTerminal; //B Non-Terminal
if (B == lastB) continue;
var beta = product.Product.GetRange(product.DotPosition + 1);
var a = product.LookAheads;
//B --> .rX, b
foreach (var production in grammar.Productions)
{
if (production.Producer != B) continue;
//b = First(βa);
var b = default(EntityCollection<Terminal>);
foreach (var term in a) b += grammar.First(beta + term);
b = (default(EntityCollection<Terminal>) != b)
? b.RemoveRedundancy() as EntityCollection<Terminal>
: new EntityCollection<Terminal>(new[] {(Terminal) "#"});
//Adding B --> .rX, b
Add(new CLRProduction(B, production.Product, b)); // gamma
}
lastB = B;
}
RemoveRedundancy();
