Method Summary

Modifier and Type	Method	Description
static @NotNull MethodType	integrateTypes(@NonNull MethodType original, int originalStartIndex, @NonNull MethodType target, int targetStartIndex, int parameterCount)	Integrates the original method-type with the target making so that specified target-type's parameters should be assignable from the corresponding ones of the integrated type.
static @NotNull MethodType	integrateTypes(@NonNull MethodType original, @NonNull MethodType target)	Shorthand for integrateTypes(MethodType, int, MethodType, int, int) for both types having the same amount of parameters each of which should be integrated.

Method Details

integrateTypes

@NotNull
public static @NotNull MethodType integrateTypes(@NonNull
 @NonNull MethodType original,
 int originalStartIndex,
 @NonNull
 @NonNull MethodType target,
 int targetStartIndex,
 int parameterCount)

Integrates the original method-type with the target making so that specified target-type's parameters should be assignable from the corresponding ones of the integrated type.

Note that indices are used to specify which parameter types should be integrated, e.g. if originalStartIndex is 2, targetStartIndex is 4 and parameterCount is 3 then the 2'nd original parameter will be integrated with the 4'th target parameter, the 3'rd original parameter will be integrated with the 5'th target parameter and the 4'th original parameter will be integrated with the 6'th target parameter.

Parameters:

original - original type which should be integrated to the target type

originalStartIndex - index from which to start in the original

target - target type to which the original type should be integrated

targetStartIndex - index from which to start in the target

parameterCount - amount of the parameters to integrate

Returns:

result of type integration, my be the same as original type

Throws:

IllegalArgumentException - if any index (including calculated last used indices) is out of its bounds

IllegalArgumentException - if any original parameter type cannot be integrated to the target parameter type

• shorthand for full integration of types with same parameter counts

integrateTypes

@NotNull
public static @NotNull MethodType integrateTypes(@NonNull
 @NonNull MethodType original,
 @NonNull
 @NonNull MethodType target)

Shorthand for integrateTypes(MethodType, int, MethodType, int, int) for both types having the same amount of parameters each of which should be integrated.

Parameters:

original - original type which should be integrated to the target type

target - target type to which the original type should be integrated

Returns:

result of type integration, my be the same as original type
