Methods

Modifier and Type	Method and Description
static BitVector	createBitVector(long initialValue, int bitCount) To be used by those tests methods which don't care about which type of bit vector is instantiated.
static void	generateSpec(int maxDimensions, int maxDimBitsSum, TestUtils.IntArrayCallback callback) Generates all possible multidimensional specifications with at most maxDimensions dimensions, and the sum of all bits for all dimensions at most maxDimBitsSum.
static void	generateSpecWithExactSum(int maxDimensions, int dimBitsSum, TestUtils.IntArrayCallback callback) Like generateSpec(int, int, IntArrayCallback), but the sum must be exact.
static BitSet	unsignedIntToLittleEndianBitSet(int i)

Method Detail

unsignedIntToLittleEndianBitSet

public static BitSet unsignedIntToLittleEndianBitSet(int i)

generateSpec

public static void generateSpec(int maxDimensions,
                int maxDimBitsSum,
                TestUtils.IntArrayCallback callback)

Generates all possible multidimensional specifications with at most maxDimensions dimensions, and the sum of all bits for all dimensions at most maxDimBitsSum. For each such multidimensional space specification it calls callback.

This method is used for exhaustive space search testing.

Parameters:

maxDimensions - maximum number of dimensions

maxDimBitsSum - maximum sum of the number of bits

callback - will be called once for each different multidimensional space specification

generateSpecWithExactSum

public static void generateSpecWithExactSum(int maxDimensions,
                            int dimBitsSum,
                            TestUtils.IntArrayCallback callback)

Like generateSpec(int, int, IntArrayCallback), but the sum must be exact.

createBitVector

public static BitVector createBitVector(long initialValue,
                        int bitCount)

To be used by those tests methods which don't care about which type of bit vector is instantiated.
