Method Detail

setVerbose

public static void setVerbose(boolean verbose)

Set the flag which indicates whether the output will be verbose and printing information about the differences between the arrays that are compared.

Parameters:

verbose - Whether the output will be verbose

compare

public static boolean compare(float[] reference,
                              float[] data)

Returns whether the given arrays are equal

Parameters:

reference - The reference array

data - the actual data array

compare

public static boolean compare(int[] reference,
                              int[] data)

Returns whether the given arrays are equal

Parameters:

reference - The reference array

data - the actual data array

compare

public static boolean compare(byte[] reference,
                              byte[] data)

Returns whether the given arrays are equal

Parameters:

reference - The reference array

data - the actual data array

compare

public static boolean compare(byte[] reference,
                              byte[] data,
                              float epsilon,
                              float threshold)

Checks if two arrays are equal within the given limits. If the arrays have different lengths, only the number of elements of the shorter array will be compared.

Parameters:

reference - The reference array

data - the actual data array

epsilon - The epsilon for the comparison

threshold - The % of array elements that may be differ by more than the given epsilon

Returns:

Whether the arrays are equal within the given limits.

compare

public static boolean compare(byte[] reference,
                              byte[] data,
                              float epsilon)

Checks if two arrays are equal within the given limits. If the arrays have different lengths, only the number of elements of the shorter array will be compared.

Parameters:

reference - The reference array

data - the actual data array

epsilon - The epsilon for the comparison

Returns:

Whether the arrays are equal within the given limits.

compare

public static boolean compare(int[] reference,
                              int[] data,
                              float epsilon,
                              float threshold)

Checks if two arrays are equal within the given limits. If the arrays have different lengths, only the number of elements of the shorter array will be compared.

Parameters:

reference - The reference array

data - the actual data array

epsilon - The epsilon for the comparison, must be >=0

threshold - The % of array elements that may be differ by more than the given epsilon

Returns:

Whether the arrays are equal within the given limits.

Checks if two arrays are equal within the given limits. If the arrays have different lengths, only the number of elements of the shorter array will be compared.

Parameters:

reference - The reference array

data - the actual data array

epsilon - The epsilon for the comparison, must be >=0

Returns:

Whether the arrays are equal within the given limits.
