Methods

Modifier and Type	Method and Description
protected static void	doRoundTripTest(IndexSegmentRegion region, int nbytes, long offset, long expectedOffset, IndexSegmentAddressManager am) Test helper forms an encoded address whose offset is relative to the specified region and then attempts to decode that address.
void	test_addressManager_decode() Test of correct decoding of addresses by the IndexSegmentAddressManager.
void	test_bitMath() Test works through the basic operations required to encode and decode an address for a node and a leaf.
void	test_encodeDecode_offsetZero() Unit test verifies that an offset of 0L (not a full address, just an offset) is correctly encoded and decoded.
void	test_regionEnum_encodeDecode() Test encoding and decoding of the region code and the offset.

Method Detail

test_bitMath

public void test_bitMath()

Test works through the basic operations required to encode and decode an address for a node and a leaf.

See Also:

IndexSegmentRegion

test_regionEnum_encodeDecode

public void test_regionEnum_encodeDecode()

Test encoding and decoding of the region code and the offset.

test_encodeDecode_offsetZero

public void test_encodeDecode_offsetZero()

Unit test verifies that an offset of 0L (not a full address, just an offset) is correctly encoded and decoded.

test_addressManager_decode

public void test_addressManager_decode()

Test of correct decoding of addresses by the IndexSegmentAddressManager.

doRoundTripTest

protected static void doRoundTripTest(IndexSegmentRegion region,
                   int nbytes,
                   long offset,
                   long expectedOffset,
                   IndexSegmentAddressManager am)

Test helper forms an encoded address whose offset is relative to the specified region and then attempts to decode that address.

Parameters:

region - The region.

nbytes - The #of bytes in the addressed record.

offset - The offset of the addressed record (relative to the start of the region).

am - The object used to decode the address.
