public ExecutableHelper(TypeResolutionHelper typeResolutionHelper)

Method Detail

overrides

public boolean overrides(Callable subTypeMethod,
                         Callable superTypeMethod)

overrides

public boolean overrides(Method subTypeMethod,
                         Method superTypeMethod)

Checks, whether subTypeMethod overrides superTypeMethod.

Parameters:

subTypeMethod - The sub type method (cannot be null).

superTypeMethod - The super type method (cannot be null).

Returns:

Returns true if subTypeMethod overrides superTypeMethod, false otherwise.

isResolvedToSameMethodInHierarchy

public boolean isResolvedToSameMethodInHierarchy(Class<?> mainSubType,
                                                 Method left,
                                                 Method right)

Checks if a pair of given methods (left and right) are resolved to the same method based on the mainSubType type.

Parameters:

mainSubType - a type at the bottom of class hierarchy to be used to lookup the methods.

left - one of the methods to check

right - another of the methods to check

Returns:

true if a pair of methods are equal left == right, or one of the methods override another one in the class hierarchy with mainSubType at the bottom, false otherwise.

getSimpleName

public static String getSimpleName(Executable executable)

getSignature

getExecutableAsString

public static String getExecutableAsString(String name,
                                           Class<?>... parameterTypes)

Returns a string representation of an executable with the given name and parameter types in the form <name>(<parameterType 0> ... <parameterType n>), e.g. for logging purposes.

Parameters:

name - the name of the executable

parameterTypes - the types of the executable's parameters

Returns:

A string representation of the given executable.
