Simple

public static final LeakDetectionPolicy Simple

Instruments 1% of the allocated buffer to track for leaks.

Advanced

public static final LeakDetectionPolicy Advanced

Instruments 1% of the allocated buffer to track for leaks, reporting stack traces of places where the buffer was used.

Method Details

values

public static LeakDetectionPolicy[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static LeakDetectionPolicy valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
