Predicates

exactTypeBase	Holds if `t` is the most precise type of `n`, if any.
getAnAncestor	Gets a direct or indirect supertype of this type, including itself.
getErasure	Gets the erased version of this type. The erasure of a erasure of a parameterized type is its generic counterpart, or `t` if `t` is already fully erased.
getSourceDeclaration	Gets the source declaration of this type, or `t` if `t` is already a source declaration.
instanceofDisjunctionGuarded	Holds if `n` is a value that is guarded by a disjunction of a dynamic type check that checks if `n` is an instance of type `t_i` where `t` is one of those `t_i`.
isExcludedFromNullAnalysis	Holds if `n` should be excluded from the set of null values even if the null analysis determines that `n` is always null.
isNullValue	Holds if `n` represents a `null` value.
step	Holds if data can flow from `n1` to `n2` in one step.
typeFlowBaseCand	Holds if `n` has type `t` and this information is discarded, such that `t` might be a better type bound for nodes where `n` flows to. This might include multiple bounds for a single node.
unbound	Holds if `t` is a raw type or parameterised type with unrestricted type arguments.

Types

Type	A type.
TypeFlowNode	A node for which type information is available. For example, expressions and method declarations.
