方法详细资料

resolveReturnType

public static Class<?> resolveReturnType(Method method,
                         Class clazz)

Determine the target type for the generic return type of the given method.

参数:

method - the method to introspect

clazz - the class to resolve type variables against

返回:

the corresponding generic parameter or return type

resolveTypeArgument

public static Class<?> resolveTypeArgument(Class clazz,
                           Class genericIfc)

Resolve the single type argument of the given generic interface against the given target class which is assumed to implement the generic interface and possibly declare a concrete type for its type variable.

参数:

clazz - the target class to check against

genericIfc - the generic interface or superclass to resolve the type argument from

返回:

the resolved type of the argument, or null if not resolvable

resolveTypeArguments

public static Class[] resolveTypeArguments(Class clazz,
                           Class genericIfc)

Resolve the type arguments of the given generic interface against the given target class which is assumed to implement the generic interface and possibly declare concrete types for its type variables.

参数:

clazz - the target class to check against

genericIfc - the generic interface or superclass to resolve the type argument from

返回:

the resolved type of each argument, with the array size matching the number of actual type arguments, or null if not resolvable
