Method Detail

flatten

public static Object flatten(Object array)

Flatten a multi-dimensional array into a one-dimensional array.

Parameters:

array - the array to flatten.

Returns:

a 1-dimensional array.

unflatten

public static Object unflatten(Object array,
                               int[] dimensions)

Un-flatten a one-dimensional array into an multi-dimensional array based on the provided dimensions.

Parameters:

array - the 1-dimensional array to un-flatten.

dimensions - the dimensions to un-flatten to.

Returns:

a multi-dimensional array of the provided dimensions.

getDimensions

public static int[] getDimensions(Object array)

getType

public static Class<?> getType(Object array)

transformArray

public static <F,T> Object transformArray(Object array,
                                          Function<F,T> transform,
                                          Class<T> toType)

Transform the values in an array from one type to another using a transformation function.

Handles multi-dimensional arrays by flattening before the transformation and un-flattening afterwards.

Parameters:

array - the original array.

transform - a function that transforms from F to T.

toType - the destination type.

Returns:

a new array of the same size and dimensions with all elements transformed from F to T using transform.
