upperBound

public JvmType.Reference upperBound()

Return the upper bound of this wildcard. This will be null if there is none.

Returns:

lowerBound

public JvmType.Reference lowerBound()

Return the lower bound of this wildcard. This will be null if there is none.

Returns:

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

compareTo

public int compareTo(JvmType t)

Specified by:

compareTo in interface java.lang.Comparable<JvmType>

usedVariables

public java.util.List<JvmType.Variable> usedVariables()

Description copied from interface: JvmType

This method returns the list of generic variables used in this type. So, for example, suppose we have:

 T = java.lang.ArrayList<? extends S>
 

Then, T.usedVariables()=[S].

Specified by:

usedVariables in interface JvmType

Returns:
