示例1: CatchClause
public CatchClause(Scope scope, ReadIdentifierExpression identifier, Statement statement)
{
Debug.Assert(scope != null, "Catch clause must have its own scope");
Debug.Assert(identifier != null, "Catch clause identifier cannot be null");
Debug.Assert(identifier.Symbol != null, "Catch clause identifier must have a symbol");
Debug.Assert(scope.GetSymbol(identifier.Symbol.Name) == identifier.Symbol, "Catch clause identifier must belong to its inner scope");
Scope = scope;
Identifier = identifier;
Statement = statement;
SourceOffset = statement.SourceOffset;
Use(Identifier);
}示例2: MakeFunctionExpression
public FunctionExpression MakeFunctionExpression(Scope scope, IIdentifier name, IIdentifierList parameters,
IStatement statement, Scope newScope)
{
var namedParams = parameters as List<ReadIdentifierExpression>;
Debug.Assert(namedParams.Count == 0 || newScope.IsFunction, "parameters must be declared in a function scope");
for (var i = 0; i < namedParams.Count; ++i)
{
var symbol = namedParams[i].Symbol;
Debug.Assert(newScope.GetSymbol(symbol.Name) == symbol && symbol.ContainerScope == newScope, "Invalid situation, parameter symbol is not in the newScope");
symbol.SymbolType = JSSymbol.SymbolTypes.Local; //already know symbol.ContainerScope.IsFunction, so no need for hoisting
symbol.ParameterIndex = i;
}
var funcName = name as ReadIdentifierExpression;
if (newScope.IsFunctionDeclaration)
{
Debug.Assert(funcName != null, "the function declaration must have a name");
Debug.Assert(scope.GetSymbol(funcName.Symbol.Name) == funcName.Symbol && funcName.Symbol.ContainerScope == scope, "Name of function declaration must exist in the outer scope");

}

if (funcName != null)
{
Debug.Assert(newScope.GetSymbol(funcName.Symbol.Name) == funcName.Symbol && funcName.Symbol.ContainerScope == newScope, "Name of function expression must exist in its own scope");
funcName.Symbol.SymbolType = JSSymbol.SymbolTypes.Local; //This is defined now in its scope, & we already know funcName.Symbol.ContainerScope.IsFunction, so no need for hoisting
}
}
var func = new FunctionExpression(newScope, funcName, namedParams, (BlockStatement)statement);
var metadata = new JSFunctionMetadata(func);
func.Metadata = metadata;
if (scope != null) scope.AddSubFunction(metadata);
return func;
}示例3: MakeCatchClause
public CatchClause MakeCatchClause(IIdentifier identifier, IStatement statement, Scope innerScope)
{
var readId = identifier as ReadIdentifierExpression;
Debug.Assert(readId != null, "Catch clause identifier {0} is not a ReadIdentifierExpression", ((Identifier)identifier));
Debug.Assert(readId.Symbol != null, "Cannot find symbol for identifier {0} in catch clause", ((Identifier)identifier));
Debug.Assert(innerScope.GetSymbol(readId.Symbol.Name) == readId.Symbol, "Catch clause identifier {0} must belong to its inner scope", readId);
readId.Symbol.SymbolType = JSSymbol.SymbolTypes.Local; //this symbol is trully local to the innerScope
return new CatchClause(innerScope, readId, (Statement)statement);
