Method Detail

canBeAssignedTo

public boolean canBeAssignedTo(Type other)

Description copied from interface: Type

Determines if the type represented by this Type object is either the same as, or is a subtype of, the type represented by other. It returns true if so, and returns false otherwise.

Specified by:

canBeAssignedTo in interface Type

Parameters:

other - the other type

Returns:

true if that condition holds

commonSupertype

public Type commonSupertype(Type other)

Description copied from interface: Type

Yields the most specific common supertype between this Type and the given one. If no common supertype exists, this method returns Untyped.INSTANCE.

Specified by:

commonSupertype in interface Type

Parameters:

other - the other type

Returns:

the most specific common supertype between this and other

toString

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

allInstances

public java.util.Collection<Type> allInstances()

Description copied from interface: Type

Yields all possible instances of this type, including itself.

Specified by:

allInstances in interface Type

Returns:

the possible instances
