class NoResolvedType
extends NoType

An unresolved type that was forward declared. So we know it exists, but that it wasn't pulled into this binary. In most cases, it behaves like a bottom type in the type lattice: no real type should be assigned to a NoResolvedType, but the NoResolvedType is a subtype of everything. In a few cases, it behaves like the unknown type: properties of this type are also NoResolved types, and comparisons to other types always have an unknown result.

Method Detail

isNoResolvedType

public boolean isNoResolvedType()

Overrides:

isNoResolvedType in class JSType

isNoType

public boolean isNoType()

Overrides:

isNoType in class NoType

isConstructor

public boolean isConstructor()

Description copied from class: JSType

Whether this type is a FunctionType that is a constructor or a named type that points to such a type.

Specified by:

isConstructor in interface TypeI

Overrides:

isConstructor in class FunctionType

isSubtype

public boolean isSubtype(JSType that)

Description copied from class: FunctionType

A function is a subtype of another if their call methods are related via subtyping and this is a subtype of that with regard to the prototype chain.

Overrides:

isSubtype in class NoType

Returns:

this <: that

isSubtype

protected boolean isSubtype(JSType that,
                            JSType.ImplCache implicitImplCache)

Description copied from class: JSType

checking isSubtype with structural interface matching

Overrides:

isSubtype in class NoType

implicitImplCache - a cache that records the checked or currently checking type pairs, for example, if previous checking found that constructor C is a subtype of interface I, then in the cache, table key <I,C> maps to IMPLEMENT status.

toStringHelper

java.lang.String toStringHelper(boolean forAnnotations)

Description copied from class: FunctionType

Informally, a function is represented by function (params): returnType where the params is a comma separated list of types, the first one being a special this:T if the function expects a known type for this.

Overrides:

toStringHelper in class NoType

Parameters:

forAnnotations - Whether this is for use in code generator annotations. Otherwise, it's for warnings.
