boolean	equals(java.lang.Object o)
ResolvedType	findBoundType(java.lang.String name)	Find type bound to specified name, if there is one; returns bound type if so, null if not.
java.lang.String	getBoundName(int index)
ResolvedType	getBoundType(int index)
java.util.List<ResolvedType>	getTypeParameters()	Accessor for getting bound types in declaration order
int	hashCode()
boolean	hasUnbound(java.lang.String name)
boolean	isEmpty()
int	size()	Returns number of bindings contained
java.lang.String	toString()
protected ResolvedType[]	typeParameterArray()
TypeBindings	withUnboundVariable(java.lang.String name)	Method for creating an instance that has same bindings as this object, plus an indicator for additional type variable that may be unbound within this context; this is needed to resolve recursive self-references.
