Field Detail
protected Set<MethodNode> alreadyVisitedMethods
protected final Map<VariableExpression, List<ClassNode>> closureSharedVariablesAssignmentTypes
A map used to store every type used in closure shared variable assignments. In a second pass, we will compute the LUB of each type and check that method calls on those variables are valid.
protected CompilationUnit compilationUnit
protected Map<Parameter, ClassNode> controlStructureVariables
protected DelegationMetadata delegationMetadata
protected final LinkedList<BinaryExpression> enclosingBinaryExpressions
protected final LinkedList<ClassNode> enclosingClassNodes
protected final LinkedList<EnclosingClosure> enclosingClosures
protected final LinkedList<Expression> enclosingMethodCalls
protected final LinkedList<MethodNode> enclosingMethods
protected final LinkedList<ErrorCollector> errorCollectors
protected Map<VariableExpression, List<ClassNode>> ifElseForWhileAssignmentTracker
This field is used to track assignments in if/else branches, for loops and while loops. For example, in the following code: if (cond) { x = 1 } else { x = '123' } the inferred type of x after the if/else statement should be the LUB of (int, String)
protected boolean isInStaticContext
protected ClassNode lastImplicitItType
The type of the last encountered "it" implicit parameter
protected Set<MethodNode> methodsToBeVisited
protected final Set<Long> reportedErrors
protected final LinkedHashSet<SecondPassExpression> secondPassExpressions
Some expressions need to be visited twice, because type information may be insufficient at some point. For example, for closure shared variables, we need a first pass to collect every type which is assigned to a closure shared variable, then a second pass to ensure that every method call on such a variable is made on a LUB.
protected SourceUnit source
protected Stack<Map<Object, List<ClassNode>>> temporaryIfBranchTypeInformation
Stores information which is only valid in the "if" branch of an if-then-else statement. This is used when the if condition expression makes use of an instanceof check
protected final StaticTypeCheckingVisitor visitor
