com.symbol.emdk.barcode.ScannerConfig.AimType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<ScannerConfig.AimType>

Enclosing class:

ScannerConfig

public static enum ScannerConfig.AimType
extends java.lang.Enum<ScannerConfig.AimType>

Describes the type of aiming to use. This will take affect only when the continuous read is set to false.

Enum Constant Summary

Enum Constants

Enum Constant and Description
CONTINUOUS_READ Scan the barcodes continuously.
PRESS_AND_RELEASE Press and release aim type; the scan status goes from idle to scanning by pressing and releasing the trigger.
PRESS_AND_SUSTAIN Press and sustain aim type; This mode helps to continue the decode session until the beamTimer is expired, barcode is decoded or cancels the read.
TIMED_HOLD Timed hold aim type; The scan status is idle until the trigger is pressed.
TIMED_RELEASE Timed release aim type; The scan status is idle until the trigger is pressed.
TRIGGER Dual-stage trigger based aiming; The standard triggering mode that remains idle until the trigger is pressed.

Enum Constant Detail

TRIGGER

public static final ScannerConfig.AimType TRIGGER

Dual-stage trigger based aiming; The standard triggering mode that remains idle until the trigger is pressed. Once the trigger is pressed a decode session is started. The decode session remains active until a barcode is decoded, the BeamTimer is expired or the trigger is released.

TIMED_HOLD

public static final ScannerConfig.AimType TIMED_HOLD

Timed hold aim type; The scan status is idle until the trigger is pressed. Once pressed an aiming session is started for a time specified by aimTimer, when this time expires a decode session is started. The decode session will remain active until the BeamTimer expires, the trigger is released or a barcode is decoded.

TIMED_RELEASE

public static final ScannerConfig.AimType TIMED_RELEASE

Timed release aim type; The scan status is idle until the trigger is pressed. Once pressed an aiming session is started and will continue until the trigger is released.If the aimTimer is expired when the trigger is released then a decode session will be started for a remaining time equal to BeamTimer or a barcode is decoded.

PRESS_AND_RELEASE

public static final ScannerConfig.AimType PRESS_AND_RELEASE

Press and release aim type; the scan status goes from idle to scanning by pressing and releasing the trigger. The decode session will remain active until the BeamTimer expired or a barcode is decoded.

CONTINUOUS_READ

public static final ScannerConfig.AimType CONTINUOUS_READ

Scan the barcodes continuously. In this mode once the trigger is pressed the user can continue scanning barcodes without releasing the trigger as long as new reads are submitted as soon as the earlier read is satisfied. This mode is useful when the user wants to perform rapid scanning. To provide better control over this feature we have added the two new reader parameters (sameSymbolTimeout, differentSymbolTimeout) that are associated with continuous reads. These reader parameters are available in both ImagerSpecific, CameraSpecific and LaserSpecific classes.

PRESS_AND_SUSTAIN

public static final ScannerConfig.AimType PRESS_AND_SUSTAIN

Press and sustain aim type; This mode helps to continue the decode session until the beamTimer is expired, barcode is decoded or cancels the read. It avoids unexpected cancellations of a read by pressing the trigger button of the device. If the trigger button of the device is pressed while the beam is ON, it has no effect.

Method Detail

values

public static ScannerConfig.AimType[] 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 (ScannerConfig.AimType c : ScannerConfig.AimType.values())
    System.out.println(c);

Returns:

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

valueOf

public static ScannerConfig.AimType 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
