Modifier and Type | Method and Description |
---|---|
boolean |

'function' in a function call.
|

|
Iterable<ObjectType> |
getCtorExtendedInterfaces()
Gets the interfaces extended by the interface associated with this type.
|
Iterable<ObjectType> |
getCtorImplementedInterfaces()
Gets the interfaces implemented by the ctor associated with this type.
|
ObjectType |
getImplicitPrototype()
Gets the implicit prototype (a.k.a.
|
FunctionType |
getOwnerFunction()
Gets the owner of this if it's a function prototype.
|
String |
getReferenceName()
Gets the reference name for this object.
|
boolean |
hasCachedValues()
Returns true if any cached values have been set for this type.
|
boolean |
hasReferenceName()
Returns true if the object is named.
|
boolean |
isNativeObjectType()
Whether this is a built-in object.
|
boolean |
isSubtype(JSType that)
Checks whether
this is a subtype of that . |
void |
matchConstraint(JSType constraint)
Modify this type so that it matches the specified type.
|
boolean |
matchesNumberContext()
This predicate is used to test whether a given type can appear in a
numeric context, such as an operand of a multiply operator.
|
boolean |
matchesObjectContext()
This predicate is used to test whether a given type can appear in an
Object context, such as the expression in a with statement. |
boolean |
matchesStringContext()
This predicate is used to test whether a given type can appear in a
String context, such as an operand of a string concat (+) operator. |
void |
matchRecordTypeConstraint(ObjectType constraintObj) |
boolean |
removeProperty(String name)
Removes the declared or inferred property from this ObjectType.
|
void |
setPropertyJSDocInfo(String propertyName,
JSDocInfo info)
Sets the docInfo for the specified property from the
JSDocInfo on its definition. |
RecordType |
toMaybeRecordType()
Downcasts this to a RecordType, or returns null if this is not
a RecordType.
|
JSType |
unboxesTo()
Turn an object type to its corresponding scalar type.

All types have at least the potential for converting to String
.
When we add externally defined types, such as a browser OM, we may choose
to add types that do not automatically convert to String
