extends java.lang.Enum<UncaughtExceptionsPolicy>

An UncaughtExceptionsPolicy defines what to do with the stack traces of exceptions that are thrown during parallel tasks execution.

Enum Constant Summary

Enum Constants

Enum Constant	Description
HIDE	Does nothing with the stack traces.
LOG_ON_SLF4J	Log exceptions via SLF4J logging API.
PRINT_AND_LOG	Does both PRINT_ON_STDERR and LOG_ON_SLF4J.
PRINT_ON_STDERR	Print uncaught exceptions' stack traces to the standard error stream.

Method Summary

Modifier and Type	Method	Description
boolean	shouldLogViaSlf4J()
boolean	shouldPrintOnStdErr()
static UncaughtExceptionsPolicy	valueOf(java.lang.String name)	Returns the enum constant of this type with the specified name.

Enum Constant Detail

HIDE

public static final UncaughtExceptionsPolicy HIDE

Does nothing with the stack traces.

Warning: when using this policy, the caller of the HCRunner will not be aware of uncaught exceptions thrown within the solver. This policy should only be used when the solver is guaranteed not to throw any exception (for instance if it wraps everything in a try/catch block)

PRINT_ON_STDERR

public static final UncaughtExceptionsPolicy PRINT_ON_STDERR

Print uncaught exceptions' stack traces to the standard error stream.

LOG_ON_SLF4J

public static final UncaughtExceptionsPolicy LOG_ON_SLF4J

Log exceptions via SLF4J logging API. This requires to provide an SLF4J implementation on the classpath, otherwise nothing will be printed at all.

PRINT_AND_LOG

public static final UncaughtExceptionsPolicy PRINT_AND_LOG

Does both PRINT_ON_STDERR and LOG_ON_SLF4J.

Method Detail

values

public static UncaughtExceptionsPolicy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (UncaughtExceptionsPolicy c : UncaughtExceptionsPolicy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static UncaughtExceptionsPolicy valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
