public class ExitStatus extends java.lang.Object implements java.io.Serializable, java.lang.Comparable<ExitStatus>
Value object used to carry information about the status of a job or step execution. ExitStatus is immutable and therefore thread-safe.- 作者:

UNKNOWN
public static final ExitStatus UNKNOWN
Convenient constant value representing unknown state - assumed not continuable.
EXECUTING
public static final ExitStatus EXECUTING
Convenient constant value representing continuable state where processing is still taking place, so no further action is required. Used for asynchronous execution scenarios where the processing is happening in another thread or process and the caller is not required to wait for the result.
COMPLETED
public static final ExitStatus COMPLETED
Convenient constant value representing finished processing.
NOOP
public static final ExitStatus NOOP
Convenient constant value representing job that did no processing (e.g. because it was already complete).
FAILED
public static final ExitStatus FAILED
Convenient constant value representing finished processing with an error.
STOPPED
public static final ExitStatus STOPPED
Convenient constant value representing finished processing with interrupted status.

方法详细资料
getExitCode
public java.lang.String getExitCode()
Getter for the exit code (defaults to blank).- 返回:
- the exit code.
getExitDescription
public java.lang.String getExitDescription()
Getter for the exit description (defaults to blank)- 返回:
String
containing the exit description.
and
public ExitStatus and(ExitStatus status)
Create a newExitStatus
with a logical combination of the exit code, and a concatenation of the descriptions. If either value has a higher severity then its exit code will be used in the result. In the case of equal severity, the exit code is replaced if the new value is alphabetically greater.
Severity is defined by the exit code:- Codes beginning with EXECUTING have severity 1
- Codes beginning with COMPLETED have severity 2
- Codes beginning with NOOP have severity 3
- Codes beginning with STOPPED have severity 4
- Codes beginning with FAILED have severity 5
- Codes beginning with UNKNOWN have severity 6
If the input is null just return this.- 参数:
status
- anExitStatus
to combine with this one.- 返回:
- a new
ExitStatus
combining the current value and the argument provided.
compareTo
public int compareTo(ExitStatus status)
- 指定者:
compareTo
在接口中java.lang.Comparable<ExitStatus>
- 参数:
status
- anExitStatus
to compare- 返回:
- greater than zero, 0, less than zero according to the severity and exit code

- 另请参阅:
Object.equals(java.lang.Object)
hashCode
public int hashCode()
Compatible with the equals implementation.- 覆盖:

Object.hashCode()
replaceExitCode
public ExitStatus replaceExitCode(java.lang.String code)
Add an exit code to an existingExitStatus
. If there is already a code present tit will be replaced.- 参数:
code
- the code to add- 返回:
- a new
ExitStatus
with the same properties but a new exit code.
isRunning
public boolean isRunning()
Check if this status represents a running process.- 返回:
- true if the exit code is "EXECUTING" or "UNKNOWN"
addExitDescription
public ExitStatus addExitDescription(java.lang.String description)
Add an exit description to an existingExitStatus
. If there is already a description present the two will be concatenated with a semicolon.- 参数:
description
- the description to add- 返回:
- a new
ExitStatus
with the same properties but a new exit description
addExitDescription
public ExitStatus addExitDescription(java.lang.Throwable throwable)
Extract the stack trace from the throwable provided and append it to the exist description.- 参数:
throwable
-Throwable
instance containing the stack trace.- 返回:
- a new ExitStatus with the stack trace appended
isNonDefaultExitStatus
public static boolean isNonDefaultExitStatus(ExitStatus status)
- 参数:
status
- the exit code to be evaluated- 返回:
- true if the value matches a known exit code
