Methods

Modifier and Type	Method and Description
void	test_keyBuilder_multiField_unicode() Test that lexiographic order is maintain when a variable length Unicode field is followed by another field.
void	test_keyBuilder_normalizeTrailingPadCharacters() Test of the ability to normalize trailing pad characters.
void	test_keyBuilder_normalizeTruncatesVeryLongStrings() Test verifies that very long strings are truncated.
void	test_keyBuilder_unicode_order() Test verifies the order among unicode sort keys, including verifying that the pad byte causes a prefix such as "bro" to sort before a term which extends that prefix, such as "brown".
void	test_keyBuilder_unicode_string_key_us_identical()
void	test_keyBuilder_unicode_string_key_us_primary() Test ability to encode unicode data into a variable length byte[] that allows direct byte-by-byte comparisons which maintain the local-specific sort order of the original strings.
void	test_keyBuilder_unicode_String_noTrailingNul() Test verifies that the trailing nul byte is not part of the key when a unicode string is appended to an IKeyBuilder.

Method Detail

test_keyBuilder_unicode_string_key_us_primary

public void test_keyBuilder_unicode_string_key_us_primary()

Test ability to encode unicode data into a variable length byte[] that allows direct byte-by-byte comparisons which maintain the local-specific sort order of the original strings.

test_keyBuilder_unicode_string_key_us_identical

public void test_keyBuilder_unicode_string_key_us_identical()

test_keyBuilder_unicode_String_noTrailingNul

public void test_keyBuilder_unicode_String_noTrailingNul()

Test verifies that the trailing nul byte is not part of the key when a unicode string is appended to an IKeyBuilder.

Note: The trailing nul byte is appended by the ICU library in order to have compatibility with their C library, but it is not of interest for Java processing. However, note that a nul byte MAY be used to separate components of a complex key.

test_keyBuilder_normalizeTrailingPadCharacters

public void test_keyBuilder_normalizeTrailingPadCharacters()

Test of the ability to normalize trailing pad characters.

test_keyBuilder_normalizeTruncatesVeryLongStrings

public void test_keyBuilder_normalizeTruncatesVeryLongStrings()

Test verifies that very long strings are truncated.

test_keyBuilder_unicode_order

public void test_keyBuilder_unicode_order()

Test verifies the order among unicode sort keys, including verifying that the pad byte causes a prefix such as "bro" to sort before a term which extends that prefix, such as "brown".

test_keyBuilder_multiField_unicode

public void test_keyBuilder_multiField_unicode()

Test that lexiographic order is maintain when a variable length Unicode field is followed by another field. This test works by comparing the original multi-field key with the multi-field key formed from the successor of the Unicode field followed by the other field:

   
   [text][nextValue] LT [successor(text)][nextValue]
