| Inner Class :class RandStructcture | |
| Method Summary | |
| public static Map | calculateDifferences(Map map1, Map map2)
| | public static Object | cast(Object invokeOn, Object toCast)
Reflexive access on JDK-1.5's Class.cast() method so we don't have to
move that out into separate classes built for JDBC-4.0. | | public static long | getCurrentTimeNanosOrMillis()
| | final static TimeZone | getDefaultTimeZone()
| | public static Object | getInstance(String className, Class[] argTypes, Object[] args)
| | final public static Object | handleNewInstance(Constructor ctor, Object[] args)
| | public static boolean | interfaceExists(String hostname)
| | public static boolean | isColdFusion()
| | public static boolean | isJdbc4()
| | protected static boolean | nanoTimeAvailable()
| | static String | newCrypt(String password, String seed)
| | static long[] | newHash(String password)
| | static String | oldCrypt(String password, String seed)
| | static long | oldHash(String password)
| | public static Object | readObject(java.sql.ResultSet resultSet, int index)
Given a ResultSet and an index into the columns of that ResultSet, read
binary data from the column which represents a serialized object, and
re-create the object.
Parameters:
resultSet - the ResultSet to use.
Parameters:
index - an index into the ResultSet. | | public static void | resultSetToMap(Map mappedValues, java.sql.ResultSet rs)
| | public static String | scramble(String message, String password)
| | public static String | stackTraceToString(Throwable ex)
Converts a nested exception into a nicer message
Parameters:
ex - the exception to expand into a message. |
| systemNanoTimeMethod | | protected static Method systemNanoTimeMethod(Code) | | |
| calculateDifferences | | public static Map calculateDifferences(Map map1, Map map2)(Code) | | |
| cast | | public static Object cast(Object invokeOn, Object toCast)(Code) | | Reflexive access on JDK-1.5's Class.cast() method so we don't have to
move that out into separate classes built for JDBC-4.0.
Parameters:
invokeOn -
Parameters:
toCast - |
| getCurrentTimeNanosOrMillis | | public static long getCurrentTimeNanosOrMillis()(Code) | | |
| handleNewInstance | | final public static Object handleNewInstance(Constructor ctor, Object[] args) throws SQLException(Code) | | Handles constructing new instance with the given constructor and wrapping
(or not, as required) the exceptions that could possibly be generated
|
| interfaceExists | | public static boolean interfaceExists(String hostname)(Code) | | Does a network interface exist locally with the given hostname?
Parameters:
hostname - the hostname (or IP address in string form) to check true if it exists, false if no, or unable to determine due to VMversion support of java.net.NetworkInterface |
| isColdFusion | | public static boolean isColdFusion()(Code) | | |
| isJdbc4 | | public static boolean isJdbc4()(Code) | | |
| nanoTimeAvailable | | protected static boolean nanoTimeAvailable()(Code) | | |
| readObject | | public static Object readObject(java.sql.ResultSet resultSet, int index) throws Exception(Code) | | Given a ResultSet and an index into the columns of that ResultSet, read
binary data from the column which represents a serialized object, and
re-create the object.
Parameters:
resultSet - the ResultSet to use.
Parameters:
index - an index into the ResultSet. the object if it can be de-serialized
throws:
Exception - if an error occurs |
| scramble | | public static String scramble(String message, String password)(Code) | | DOCUMENT ME!
Parameters:
message - DOCUMENT ME!
Parameters:
password - DOCUMENT ME! DOCUMENT ME! |
| stackTraceToString | | public static String stackTraceToString(Throwable ex)(Code) | | Converts a nested exception into a nicer message
Parameters:
ex - the exception to expand into a message. a message containing the exception, the message (if any), and astacktrace. |
