Class FloatMismatch

java.lang.Object

io.spine.change.FloatMismatch

public final class FloatMismatch
extends java.lang.Object

Utility class for working with float values in ValueMismatches.

Method Summary

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

Method Detail

expectedZero

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

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

unpackExpected

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

Obtains expected float value from the passed mismatch.

Throws:

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

unpackActual

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

Obtains actual float value from the passed mismatch.

Throws:

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

unpackNewValue

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

Obtains new float value from the passed mismatch.

Throws:

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