Field Details

MIN_DELAY

public static final long MIN_DELAY

The minimum delay between scans.

• Constant Field Values

MAX_OBTAIN_DELAY

public static final long MAX_OBTAIN_DELAY

The maximum delay between scans when obtaining from the master.

See Also:

• Constant Field Values

MAX_OBTAIN_INCOMPLETE_DELAY

public static final long MAX_OBTAIN_INCOMPLETE_DELAY

The delay when obtaining from the master is incomplete (master out of entropy). This is used to avoid hitting the master stupid-hard when it is depleted.

• Constant Field Values

MAX_DESIRED_DELAY

public static final long MAX_DESIRED_DELAY

The maximum delay between scans when at the desired entropy.

GET_MASTER_ENTROPY_NEEDED_INTERVAL

public static final long GET_MASTER_ENTROPY_NEEDED_INTERVAL

The minimum interval between calls to getMasterEntropyNeeded().

ERROR_DELAY

public static final long ERROR_DELAY

The delay after an error occurs.
