Constructor Details

ComparableAssertion

public ComparableAssertion(T value)

Constructor.

Parameters:

value - The object being tested.
Can be null.

Method Details

create

public static <T extends Comparable<T>>
ComparableAssertion<T> create(T value)

Static creator.

Type Parameters:

T - The value type.

Parameters:

value - The object being tested.
Can be null.

Returns:

A new assertion object.

setMsg

public ComparableAssertion<T> setMsg(String msg,
 Object... args)

Description copied from class: Assertion

Allows you to override the assertion failure message.

String can contain "{msg}" to represent the original message.

Example:

import static org.apache.juneau.assertions.Assertions.*; // Throws an assertion with a custom message instead of the default "Value was null." assertString(myString) .setMsg("My string was bad: {msg}") .isNotNull();

Overrides:

setMsg in class FluentComparableAssertion<T extends Comparable<T>,ComparableAssertion<T extends Comparable<T>>>

Parameters:

msg - The assertion failure message.

args - Optional message arguments.

Returns:

This object.

setOut

public ComparableAssertion<T> setOut(PrintStream value)

Description copied from class: Assertion

If an error occurs, send the error message to the specified stream instead of STDERR.

Overrides:

setOut in class FluentComparableAssertion<T extends Comparable<T>,ComparableAssertion<T extends Comparable<T>>>

Parameters:

value - The output stream. Can be null to suppress output.

Returns:

This object.

setSilent

public ComparableAssertion<T> setSilent()

Description copied from class: Assertion

Suppresses output to STDERR.

This is the equivalent to calling out(null).

Overrides:

setSilent in class FluentComparableAssertion<T extends Comparable<T>,ComparableAssertion<T extends Comparable<T>>>

Returns:

This object.

setStdOut

public ComparableAssertion<T> setStdOut()

Description copied from class: Assertion

If an error occurs, send the error message to STDOUT instead of STDERR.

Overrides:

setStdOut in class FluentComparableAssertion<T extends Comparable<T>,ComparableAssertion<T extends Comparable<T>>>

Returns:

This object.

setThrowable

public ComparableAssertion<T> setThrowable(Class<? extends RuntimeException> value)

Description copied from class: Assertion

If an error occurs, throw this exception instead of the standard AssertionError.

The throwable class must have a public constructor that takes in any of the following parameters:

• Throwable - The caused-by exception (if there is one).
• String - The assertion failure message.

If the throwable cannot be instantiated, a RuntimeException is thrown instead.

Example:

import static org.apache.juneau.assertions.Assertions.*; // Throws a BadRequest instead of an AssertionError if the string is null. assertString(myString) .setThrowable(BadRequest.class) .isNotNull();

Overrides:

setThrowable in class FluentComparableAssertion<T extends Comparable<T>,ComparableAssertion<T extends Comparable<T>>>

Parameters:

value - The new value for this setting.

Returns:

This object.
