Class IntMismatch

java.lang.Object

io.spine.change.IntMismatch

public final class IntMismatch
extends java.lang.Object

Utility class for working with int values in ValueMismatches.

Method Summary

Modifier and Type	Method and Description
static io.spine.change.ValueMismatch	expectedNonZero(int expected, int newValue, int version) Creates ValueMismatch for the case of discovering zero value, when a non zero amount was expected by a command.
static io.spine.change.ValueMismatch	expectedZero(int actual, int newValue, int version) Creates ValueMismatch for the case of discovering not zero value, when a zero amount was expected by a command.
static io.spine.change.ValueMismatch	of(int expected, int actual, int newValue, int version) Creates a new instance of ValueMismatch with the passed values for an integer attribute.
static io.spine.change.ValueMismatch	unexpectedValue(int expected, int actual, int newValue, int version) Creates ValueMismatch for the case of discovering a value different than by a command.
static int	unpackActual(io.spine.change.ValueMismatch mismatch) Obtains actual int value from the passed mismatch.
static int	unpackExpected(io.spine.change.ValueMismatch mismatch) Obtains expected int value from the passed mismatch.
static int	unpackNewValue(io.spine.change.ValueMismatch mismatch) Obtains new int value from the passed mismatch.

Method Detail

expectedZero

public static io.spine.change.ValueMismatch expectedZero(int actual,
                                                         int newValue,
                                                         int version)

Creates ValueMismatch for the case of discovering not zero value, when a zero amount was expected by a command.

Parameters:

actual - the value discovered instead of zero

newValue - the new value requested in the command

version - the version of the entity in which the mismatch is discovered

Returns:

new ValueMismatch instance

expectedNonZero

public static io.spine.change.ValueMismatch expectedNonZero(int expected,
                                                            int newValue,
                                                            int version)

Creates ValueMismatch for the case of discovering zero value, when a non zero amount was expected by a command.

Parameters:

expected - the value of the field that the command wanted to clear

newValue - the new value requested in the command

version - the version of the entity in which the mismatch is discovered

Returns:

new ValueMismatch instance

unexpectedValue

public static io.spine.change.ValueMismatch unexpectedValue(int expected,
                                                            int actual,
                                                            int newValue,
                                                            int version)

Creates ValueMismatch for the case of discovering a value different than by a command.

Parameters:

expected - the value expected by the command

actual - the value discovered instead of the expected string

newValue - the new value requested in the command

version - the version of the entity in which the mismatch is discovered

Returns:

new ValueMismatch instance

of

public static io.spine.change.ValueMismatch of(int expected,
                                               int actual,
                                               int newValue,
                                               int version)

Creates a new instance of ValueMismatch with the passed values for an integer attribute.

unpackExpected

public static int unpackExpected(io.spine.change.ValueMismatch mismatch)

Obtains expected int value from the passed mismatch.

Throws:

java.lang.RuntimeException - if the passed instance represent a mismatch of non-int values

unpackActual

public static int unpackActual(io.spine.change.ValueMismatch mismatch)

Obtains actual int value from the passed mismatch.

Throws:

java.lang.RuntimeException - if the passed instance represent a mismatch of non-int values

unpackNewValue

public static int unpackNewValue(io.spine.change.ValueMismatch mismatch)

Obtains new int value from the passed mismatch.

Throws:

java.lang.RuntimeException - if the passed instance represent a mismatch of non-int values
