Method Detail

matches

public boolean matches(Set<Type> requiredTypes,
              Set<Type> beanTypes)

Description copied from interface: AssignabilityRules

Check whether at least one of the requiredTypes matches a type in beanTypes

Specified by:

matches in interface AssignabilityRules

Parameters:

requiredTypes - the requiredTypes

beanTypes - the beanTypes

Returns:

can we assign some type from requiredTypes to some type in beanTypes

matches

public boolean matches(Type requiredType,
              Set<? extends Type> beanTypes)

Description copied from interface: AssignabilityRules

Check whether requiredType matches a type in beanTypes

Specified by:

matches in interface AssignabilityRules

Parameters:

requiredType - the requiredType

beanTypes - the beanTypes

Returns:

can we assign requiredType to some type in beanTypes

getUppermostTypeVariableBounds

protected Type[] getUppermostTypeVariableBounds(TypeVariable<?> bound)

boundsMatch

protected boolean boundsMatch(Type[] upperBounds,
                  Type[] stricterUpperBounds)

Returns true iff for each upper bound T, there is at least one bound from stricterUpperBounds assignable to T. This reflects that stricterUpperBounds are at least as strict as upperBounds are.

Arguments passed to this method must be legal java bounds, i.e. bounds returned by TypeVariable.getBounds(), WildcardType.getUpperBounds() or WildcardType.getLowerBounds().

lowerBoundsOfWildcardMatch

protected boolean lowerBoundsOfWildcardMatch(Type parameter,
                                 WildcardType requiredParameter)

lowerBoundsOfWildcardMatch

protected boolean lowerBoundsOfWildcardMatch(Type[] beanParameterBounds,
                                 WildcardType requiredParameter)

upperBoundsOfWildcardMatch

protected boolean upperBoundsOfWildcardMatch(WildcardType requiredParameter,
                                 Type parameter)
