Constructor Details

DiskBalancerException

public DiskBalancerException(String message,
 DiskBalancerException.Result result)

Constructs an IOException with the specified detail message.

Parameters:

message - The detail message (which is saved for later retrieval by the Throwable.getMessage() method)

DiskBalancerException

public DiskBalancerException(String message,
 Throwable cause,
 DiskBalancerException.Result result)

Constructs an IOException with the specified detail message and cause.

Note that the detail message associated with cause is not automatically incorporated into this exception's detail message.

Parameters:

message - The detail message (which is saved for later retrieval by the Throwable.getMessage() method)

cause - The cause (which is saved for later retrieval by the Throwable.getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)

DiskBalancerException

public DiskBalancerException(Throwable cause,
 DiskBalancerException.Result result)

Constructs an IOException with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message of cause). This constructor is useful for IO exceptions that are little more than wrappers for other throwables.

Parameters:

cause - The cause (which is saved for later retrieval by the Throwable.getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
