Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`<A> A`	`accept(PsiTypeVisitor<A> visitor)` Passes the type to the specified visitor.
`static PsiWildcardType`	`createExtends(PsiManager manager, PsiType bound)`
`static PsiWildcardType`	`createSuper(PsiManager manager, PsiType bound)`
`static PsiWildcardType`	`createUnbounded(PsiManager manager)`
`boolean`	`equals(java.lang.Object o)`
`boolean`	`equalsToText(java.lang.String text)` Checks if the specified string is equivalent to the canonical text of the type.
`PsiType`	`getBound()` Use this method to obtain a bound of wildcard type.
`java.lang.String`	`getCanonicalText(boolean annotated)` Returns canonical representation of the type (all references fully-qualified).
`PsiType`	`getExtendsBound()` A lower bound that this wildcard imposes on type parameter value. That is: for `? extends XXX`: `XXX` for `? super XXX`: `java.lang.Object` for `?`: `java.lang.Object`
`java.lang.String`	`getInternalCanonicalText()` Return canonical text of the type with some internal details added for presentational purposes.
`PsiManager`	`getManager()`
`java.lang.String`	`getPresentableText(boolean annotated)` Returns text of the type that can be presented to a user (references normally non-qualified).
`GlobalSearchScope`	`getResolveScope()` Returns the scope in which the reference to the underlying class of a class type is searched.
`PsiType`	`getSuperBound()` An upper bound that this wildcard imposes on type parameter value. That is: for `? extends XXX`: null type for `? super XXX`: `XXX` for `?`: null type
`PsiType []`	`getSuperTypes()` Returns the list of superclass types for a class type.
`int`	`hashCode()`
`boolean`	`isBounded()`
`boolean`	`isExtends()` Returns whether this is a lower bound (`? extends XXX`).
`boolean`	`isSuper()` Returns whether this is an upper bound (`? super XXX`).
`boolean`	`isValid()` Checks if the type is currently valid.
`JvmType`	`lowerBound()` A lower bound that this wildcard imposes on type parameter value. That is: for `? extends XXX`: empty iterable for `? super XXX`: `XXX` for `?`: null type
`JvmType`	`upperBound()` An upper bound that this wildcard imposes on type parameter value. That is: for `? extends XXX`: `XXX` for `? super XXX`: `java.lang.Object` for `?`: `java.lang.Object`
