public final class ValueGenerators
extends java.lang.Object

Utility class containing factory methods for ValueGenerator

Method Summary

Modifier and Type	Method and Description
static <T> ValueGenerator<T>	constant(T constant) Returns a value generator which always returns the same, given value.
static DateSequenceValueGenerator	dateSequence() Returns a value generator that returns a sequence of dates, starting at a given date and incremented by a given time, specified as an increment and a calendar field.
static SequenceValueGenerator	sequence() Returns a value generator which generates a sequence of long values starting with 1, with an increment of 1.
static StringSequenceValueGenerator	stringSequence(java.lang.String prefix) Returns a value generator that returns a string prefix followed by a sequence number, optionally left-padded with 0 to ensure a correct ordering (for example: CODE_001, CODE_002, etc.).

Method Detail

sequence

public static SequenceValueGenerator sequence()

Returns a value generator which generates a sequence of long values starting with 1, with an increment of 1. The starting value and increment can be customized using

     ValueGenerators.increment().startingAt(1000).incrementingBy(5)
 

constant

public static <T> ValueGenerator<T> constant(@Nullable
                                             T constant)

Returns a value generator which always returns the same, given value.

stringSequence

public static StringSequenceValueGenerator stringSequence(@Nonnull
                                                          java.lang.String prefix)

Returns a value generator that returns a string prefix followed by a sequence number, optionally left-padded with 0 to ensure a correct ordering (for example: CODE_001, CODE_002, etc.). The returned generator starts the sequence at 1 and increments by 1, and doesn't pad the numbers.

Parameters:

prefix - the prefix before the generated number (for example: "CODE_").

dateSequence

public static DateSequenceValueGenerator dateSequence()

Returns a value generator that returns a sequence of dates, starting at a given date and incremented by a given time, specified as an increment and a calendar field. The returned generator starts today at 00:00:00 and increments by 1 day by default.
