public class AssertionError

extends Error

Untamed: Thrown to indicate that an assertion has failed.

The seven one-argument public constructors provided by this class ensure that the assertion error returned by the invocation:

     new AssertionError(expression)
 

has as its detail message the string conversion of expression (as defined in The Java Language Specification, Second Edition, Section 15.18.1.1), regardless of the type of expression.

Constructor Summary

	AssertionError() Enabled: Constructs an AssertionError with no detail message.
	AssertionError(boolean detailMessage) Enabled: Constructs an AssertionError with its detail message derived from the specified boolean, which is converted to a string as defined in The Java Language Specification, Second Edition, Section 15.18.1.1.
	AssertionError(char detailMessage) Enabled: Constructs an AssertionError with its detail message derived from the specified char, which is converted to a string as defined in The Java Language Specification, Second Edition, Section 15.18.1.1.
	AssertionError(double detailMessage) Enabled: Constructs an AssertionError with its detail message derived from the specified double, which is converted to a string as defined in The Java Language Specification, Second Edition, Section 15.18.1.1.
	AssertionError(float detailMessage) Enabled: Constructs an AssertionError with its detail message derived from the specified float, which is converted to a string as defined in The Java Language Specification, Second Edition, Section 15.18.1.1.

Constructor Detail

AssertionError

public AssertionError()

Enabled: Constructs an AssertionError with no detail message.

AssertionError

private AssertionError(String detailMessage)

This internal constructor does no processing on its string argument, even if it is a null reference. The public constructors will never call this constructor with a null argument.

AssertionError

public AssertionError(Object detailMessage)

Enabled: Constructs an AssertionError with its detail message derived from the specified object, which is converted to a string as defined in The Java Language Specification, Second Edition, Section 15.18.1.1.

If the specified object is an instance of Throwable, it becomes the cause of the newly constructed assertion error.

Parameters:

detailMessage - value to be used in constructing detail message

Throwable.getCause()

AssertionError

public AssertionError(boolean detailMessage)

Enabled: Constructs an AssertionError with its detail message derived from the specified boolean, which is converted to a string as defined in The Java Language Specification, Second Edition, Section 15.18.1.1.

Parameters:

detailMessage - value to be used in constructing detail message

AssertionError

public AssertionError(char detailMessage)

Enabled: Constructs an AssertionError with its detail message derived from the specified char, which is converted to a string as defined in The Java Language Specification, Second Edition, Section 15.18.1.1.

Parameters:

detailMessage - value to be used in constructing detail message

AssertionError

public AssertionError(int detailMessage)

Enabled: Constructs an AssertionError with its detail message derived from the specified int, which is converted to a string as defined in The Java Language Specification, Second Edition, Section 15.18.1.1.

Parameters:

detailMessage - value to be used in constructing detail message

AssertionError

public AssertionError(long detailMessage)

Enabled: Constructs an AssertionError with its detail message derived from the specified long, which is converted to a string as defined in The Java Language Specification, Second Edition, Section 15.18.1.1.

Parameters:

detailMessage - value to be used in constructing detail message

AssertionError

public AssertionError(float detailMessage)

Enabled: Constructs an AssertionError with its detail message derived from the specified float, which is converted to a string as defined in The Java Language Specification, Second Edition, Section 15.18.1.1.

Parameters:

detailMessage - value to be used in constructing detail message

AssertionError

public AssertionError(double detailMessage)

Enabled: Constructs an AssertionError with its detail message derived from the specified double, which is converted to a string as defined in The Java Language Specification, Second Edition, Section 15.18.1.1.

Parameters:

detailMessage - value to be used in constructing detail message
