Class DoubleMismatch

java.lang.Object

io.spine.change.DoubleMismatch

public final class DoubleMismatch
extends java.lang.Object

Utility class for working with double values in ValueMismatches.

Method Summary

Modifier and Type	Method and Description
static io.spine.change.ValueMismatch	expectedNonZero(double expected, double 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(double actual, double 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(double expected, double actual, double newValue, int version) Creates a new instance of ValueMismatch with the passed values for a double attribute.
static io.spine.change.ValueMismatch	unexpectedValue(double expected, double actual, double newValue, int version) Creates ValueMismatch for the case of discovering a value different than by a command.
static double	unpackActual(io.spine.change.ValueMismatch mismatch) Obtains actual double value from the passed mismatch.
static double	unpackExpected(io.spine.change.ValueMismatch mismatch) Obtains expected double value from the passed mismatch.
static double	unpackNewValue(io.spine.change.ValueMismatch mismatch) Obtains new double value from the passed mismatch.

Method Detail

expectedZero

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

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

unpackExpected

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

Obtains expected double value from the passed mismatch.

Throws:

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

unpackActual

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

Obtains actual double value from the passed mismatch.

Throws:

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

unpackNewValue

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

Obtains new double value from the passed mismatch.

Throws:

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