Method Detail

create

public static KeeperException create(KeeperException.Code code,
                                     String path)

All non-specific keeper exceptions should be constructed via this factory method in order to guarantee consistency in error codes and such. If you know the error code, then you should construct the special purpose exception directly. That will allow you to have the most specific possible declarations of what exceptions might actually be thrown.

Parameters:

code - The error code.

path - The ZooKeeper path being operated on.

Returns:

The specialized exception, presumably to be thrown by the caller.

create

@Deprecated
public static KeeperException create(int code,
                                                 String path)

Deprecated. deprecated in 3.1.0, use create(Code, String) instead

create

@Deprecated
public static KeeperException create(int code)

Deprecated. deprecated in 3.1.0, use create(Code) instead

create

public static KeeperException create(KeeperException.Code code)

All non-specific keeper exceptions should be constructed via this factory method in order to guarantee consistency in error codes and such. If you know the error code, then you should construct the special purpose exception directly. That will allow you to have the most specific possible declarations of what exceptions might actually be thrown.

Parameters:

code - The error code of your new exception. This will also determine the specific type of the exception that is returned.

Returns:

The specialized exception, presumably to be thrown by the caller.

setCode

@Deprecated
public void setCode(int code)

Deprecated. deprecated in 3.1.0, exceptions should be immutable, this method should not be used

Set the code for this exception

Parameters:

code - error code

getCode

@Deprecated
public int getCode()

Deprecated. deprecated in 3.1.0, use code() instead

Read the error code for this exception

Returns:

the error code for this exception

code

public KeeperException.Code code()

Read the error Code for this exception

Returns:

the error Code for this exception

getPath

public String getPath()

Read the path for this exception

Returns:

the path associated with this error, null if none

getMessage

public String getMessage()

Overrides:

getMessage in class Throwable

getResults

public List<OpResult> getResults()

If this exception was thrown by a multi-request then the (partial) results and error codes can be retrieved using this getter.

Returns:

A copy of the list of results from the operations in the multi-request.

Since:

3.4.0
