Constructor Detail

AbstractNextMaxValueProvider

public AbstractNextMaxValueProvider()

Method Detail

getNextIntValue

public int getNextIntValue()

getNextLongValue

public long getNextLongValue()

getNextDoubleValue

setPrefixWithZero

public void setPrefixWithZero(boolean prefixWithZero,
                              int length)

Sets the prefixWithZero.

Parameters:

prefixWithZero - The prefixWithZero to set

getNextKey

protected abstract long getNextKey(int type)

Give the key to use as a long.

Parameters:

type - The Sql type of the key in the database.

Returns:

The key to use as a long. It will eventually be converted later in another format by the public concrete methods of this class.

getLongValue

                            int type)

Parameters:

sqlf - The compiled SqlFunction

type - SqlType returned by the SqlFunction

Returns:

The result of the SqlFunction as a long
