Enum Constants Enum Constant Description NO_SCAN
Equivalent to scan interval of zero.SCAN_AT_FIXED_INTERVAL
Trigger continuous scan at given interval.SCAN_AT_FIXED_INTERVAL_WITH_PAUSE_AFTER_WRITE
Trigger continuous scan at given interval but introduce a pause after a write operation to allow the device time to process data without having to respond to further enumeration requests.

NO_SCAN
public static final ScanMode NO_SCAN
Equivalent to scan interval of zero.
-
SCAN_AT_FIXED_INTERVAL
public static final ScanMode SCAN_AT_FIXED_INTERVAL
Trigger continuous scan at given interval.
-
SCAN_AT_FIXED_INTERVAL_WITH_PAUSE_AFTER_WRITE
public static final ScanMode SCAN_AT_FIXED_INTERVAL_WITH_PAUSE_AFTER_WRITE
Trigger continuous scan at given interval but introduce a pause after a write operation to allow the device time to process data without having to respond to further enumeration requests. This can be a useful strategy for handling devices with constrained processing power and/or limited USB stacks. Note this will affect the time to generate a device attach/detach event since scanning will be paused.

values
public static ScanMode[] 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 (ScanMode c : ScanMode.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static ScanMode 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 namejava.lang.NullPointerException
- if the argument is null
