Method Detail

assertThat

public static <T> void assertThat(T value,
                                  Predicate<T> assertion,
                                  String exceptionMessage)
                           throws AxonConfigurationException

Assert that the given value will result to true through the assertion Predicate. If not, an AxonConfigurationException is thrown containing the provided exceptionMessage.

Type Parameters:

T - a generic specifying the type of the value, which is the input for the assertion

Parameters:

value - a T specifying the value to assert

assertion - a Predicate to test value against

exceptionMessage - The message for the exception.

Throws:

AxonConfigurationException - if the value asserts to false by the assertion

assertNonNull

public static <T> void assertNonNull(T value,
                                     String exceptionMessage)
                              throws AxonConfigurationException

Assert that the given value is non null. If not, an AxonConfigurationException is thrown containing the provided exceptionMessage.

Type Parameters:

T - a generic specifying the type of the value, which is the input for the assertion

Parameters:

value - a T specifying the value to assert

exceptionMessage - The message for the exception.

Throws:

AxonConfigurationException - if the value equals null

assertPositive

public static void assertPositive(int i,
                                  String exceptionMessage)

Assert that the given value is positive, meaning greater than, or equal to, zero. If not, an AxonConfigurationException is thrown containing the provided {code exceptionMessage}.

Parameters:

i - the value to assert

exceptionMessage - the message for the exception

assertPositive

public static void assertPositive(long l,
                                  String exceptionMessage)

Assert that the given value is positive, meaning greater than, or equal to, zero. If not, an AxonConfigurationException is thrown containing the provided {code exceptionMessage}.

Parameters:

l - the value to assert

exceptionMessage - the message for the exception

assertStrictPositive

public static void assertStrictPositive(int i,
                                        String exceptionMessage)

Assert that the given value is strictly positive, meaning greater than zero. If not, an AxonConfigurationException is thrown containing the provided {code exceptionMessage}.

Parameters:

i - the value to assert

exceptionMessage - the message for the exception.

assertStrictPositive

public static void assertStrictPositive(long l,
                                        String exceptionMessage)

Assert that the given value is strictly positive, meaning greater than zero. If not, an AxonConfigurationException is thrown containing the provided {code exceptionMessage}.

Parameters:

l - the value to assert

exceptionMessage - the message for the exception.

assertNonEmpty

public static void assertNonEmpty(String string,
                                  String exceptionMessage)

Assert that the given string is not null and does not equal an empty String. If not, an AxonConfigurationException is thrown containing the provided exceptionMessage.

Parameters:

string - the value to assert

exceptionMessage - the message for the exception.
