Constructor Details

ThrowableCause

public ThrowableCause(Throwable throwable)

Construct a cause based on the given throwable. Uses the fully qualified class name as the type and the Throwable.getMessage() as the message.

Parameters:

throwable - The throwable to base this cause on.

ThrowableCause

public ThrowableCause(String type,
 String message)

Constructs a cause based on the give type and message.

Parameters:

type - The type of this cause.

message - The message of this cause.

Method Details

asCause

public static ThrowableCause asCause(Throwable cause)

Return the given cause as a ThrowableCause.

If the given cause is an instance of ThrowableCause it is returned as is. Otherwise, this method constructs a new instance through ThrowableCause(Throwable).

Parameters:

cause - The Throwable to map to a ThrowableCause.

Returns:

A ThrowableCause based on the given cause, or the cause as-is if it is an instance of ThrowableCause.

truncated

public static ThrowableCause truncated(Throwable throwable)

Construct a ThrowableCause based on the given throwable, truncating the message to a maximum size of TRUNCATED_MESSAGE_SIZE.

Should be used to ensure the Cause fits in the desired dead-letter storage solution.

Parameters:

throwable - The Throwable to adjust to a ThrowableCause.

Returns:

A ThrowableCause based on the given throwable for which the message is truncated to TRUNCATED_MESSAGE_SIZE.

truncated

public static ThrowableCause truncated(Throwable throwable,
 int messageSize)

Construct a ThrowableCause based on the given throwable, truncating the message to the given messageSize.

Should be used to ensure the Cause fits in the desired dead-letter storage solution.

Parameters:

throwable - The Throwable to adjust to a ThrowableCause.

messageSize - The size to truncate the Throwable.getMessage() to, to be able to fit in databases.

Returns:

A ThrowableCause based on the given throwable for which the message is truncated to given messageSize.

type

public String type()

Description copied from interface: Cause

Returns the type of dead lettering cause. The type can, for example, reflect the fully qualified class name of a Throwable.

Specified by:

type in interface Cause

Returns:

The type of this dead lettering cause.

message

public String message()

Description copied from interface: Cause

A message describing a cause for dead lettering. The message() can, for example, reflect the message of a Throwable.

Specified by:

message in interface Cause

Returns:

The message describing this cause's reason for dead lettering.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Throwable
