Method Detail

convertToGenericType

public static <T> T convertToGenericType(java.lang.Class<?> type)

convertToGenericType

public static ImageDataType convertToGenericType(ImageDataType type)

convertGenericToSpecificType

public static <T> T convertGenericToSpecificType(java.lang.Class<?> type)

If an image is to be created then the generic type can't be used a specific one needs to be. An arbitrary specific image type is returned here.

createSubImageOf

public static <T extends ImageBase> T createSubImageOf(T input)

Returns an image which is a sub-image but contains the same values of the input image. Use for testing compliance with sub-images. The subimage is created by creating a larger image, copying over the input image into the inner portion, then creating a subimage of the copied part.

createSubImageOf_S

public static <T extends ImageSingleBand> T createSubImageOf_S(T input)

createSubImageOf_I

public static <T extends ImageInterleaved> T createSubImageOf_I(T input)

createSubImageOf_MS

public static <T extends MultiSpectral> T createSubImageOf_MS(T input)

checkImageDimensionValidation

public static void checkImageDimensionValidation(java.lang.Object testClass,
                                 int numFunctions)

Searches for functions that accept only images and makes sure they only accept images which have he same width and height.

Parameters:

testClass - Instance of the class being tested

checkSubImage

public static void checkSubImage(java.lang.Object testClass,
                 java.lang.String function,
                 boolean checkEquals,
                 java.lang.Object... inputParam)

Tests the specified function with the original image provided and with an equivalent sub-image. The two results are then compared. The function being tested must only have one input parameter of type ImageUInt8.

Parameters:

testClass - Instance of the class that contains the function being tested.

function - The name of the function being tested.

checkEquals - Checks to see if the two images have been modified the same way on output

inputParam - The original input parameters

findMethod

public static java.lang.reflect.Method findMethod(java.lang.Class<?> type,
                                  java.lang.String name,
                                  java.lang.Class<?>... params)

Searches for a function which is a perfect match. if none it exists it checks to see if any matches that could accept an input of the specified type. If there is only one such match that is returned.

callStaticMethod

public static void callStaticMethod(java.lang.Class<?> classType,
                    java.lang.String name,
                    java.lang.Object... inputs)

Looks up the static method then passes in the specified inputs.

findMethodThenCall

public static int findMethodThenCall(java.lang.Object owner,
                     java.lang.String ownerMethod,
                     java.lang.Class target,
                     java.lang.String targetMethod)

Searches for all functions with the specified name in the target class. Once it finds that function it invokes the specified function in the owner class. That function must take in a Method as its one and only parameter. The method will be one of the matching ones in the target class.

Parameters:

owner -

ownerMethod -

target -

targetMethod -

Returns:

The number of times 'targetMethod' was found and called.
