Methods

Modifier and Type	Method and Description
void	doTestGet(int offsetBits, int limit) Helper performs random tests of WormAddressManager.toAddr(int, long) and is intended to verify both consistency of encoding and decoding and correct rejection when encoding.
static long	nextAddr(Random r, WormAddressManager am) Returns a legal random address and NULL 5% of the time.
static int	nextByteCount(Random r, WormAddressManager am) Next random byte count in [0:maxByteCount], but never more than Integer.MAX_VALUE bytes and zero (0) 5% of the time.
static long	nextNonZeroAddr(Random r, WormAddressManager am) Returns a legal random non-NULL address.
static long	nextNonZeroAddr(Random r, WormAddressManager am, long limit) Returns a legal random non-NULL address that does not extend as far as limit.
static int	nextNonZeroByteCount(Random r, WormAddressManager am) Next random legal non-zero byte count less than maxByteCount and never more than Integer.MAX_VALUE bytes.
static long	nextNonZeroOffset(Random r, WormAddressManager am) Next non-zero random byte offset less than maxOffset.
static long	nextOffset(Random r, WormAddressManager am) Next random byte offset and 0L 5% of the time.
void	test_canNotConstructNULLs() Verify that WormAddressManager.toAddr(int, long) will reject a zero byte count or a zero offset since the value 0L is reserved to represent a null reference.
void	test_ctor_32bits() Test of constructor when splitting the long integer into two 32-bit unsigned integer components (offset and #bytes).
void	test_ctor_48bits() Test of constructor when splitting the long integer into a 48-bit unsigned integer (offset) and a 16-bit unsigned integer (#bytes).
void	test_ctor_correctRejection()
void	test_encodeDecode_offsetBits32_01() One of a series of tests of encoding and decoding addresses that have proven themselves to be edge conditions in the code.
void	test_encodeDecode_offsetBits48_01()
void	test_get_32() Test of encoding and decoding addressed with a small set of 32 bit offsets.
void	test_get_48() Test of encoding and decoding addressed with a small set of 48 bit offsets.
void	test_get() Test of encoding and decoding addresses with a set of addresses selected from each of the legal values of the offsetBits.
void	test_static_getMaxByteCount()
void	test_toAddr_correctRejection_byteCount() Test that IAddressManager.toAddr(int, long) will correctly reject requests where the byte count is invalid.
void	test_toAddr_correctRejection_byteOffset() Test that IAddressManager.toAddr(int, long) will correctly reject requests where the byte offset is invalid.

doTestGet

public void doTestGet(int offsetBits,
             int limit)

Helper performs random tests of WormAddressManager.toAddr(int, long) and is intended to verify both consistency of encoding and decoding and correct rejection when encoding.

Parameters:

offsetBits -

nextAddr

public static long nextAddr(Random r,
            WormAddressManager am)
