Device Property

CrDeviceProperty

Class describing device properties. Includes information about the data type, current value, and supported values. Additionally, it indicates if the property is currently modifiable. Check the Device Property List for the Device Property Code(CrDevicePropertyCode enumerations) supported in the current release. See Get the Camera Properties and SetDeviceProperty() for usage. Details of each device properties are described in Parameter description.

void Alloc(const CrInt32u size, const CrInt32u getSetSize, const CrInt16u getStrSize)	It cannot be used.
bool IsGetEnableCurrentValue() const	Checks to see if this device property is readable.
bool IsSetEnableCurrentValue() const	Checks to see if this device property is writable.
CrInt32u GetCode() const	Get the CrDevicePropertyCode used by this device property. Defined in CrDeviceProperty.h as CrDevicePropertyCode
CrDataType GetValueType() const	Get the CrDataType used by this device property. Defined in CrDefines.h as CrDataType.
CrPropertyEnableFlag GetPropertyEnableFlag() const	Get the CrPropertyEnableFlag that represents the enable status for this device property. Defined in CrDeviceProperty.h as CrPropertyEnableFlag. When enableFlag is Disable, Setter/Getter API is invalid (not guaranteed)
CrInt64u GetCurrentValue() const	Get the current value. Details of the value are given in each device property in the Parameter description.
CrInt16u* GetCurrentStr() const	Get the string value when the GetValueType() is CrDataType_STR. The string length is set to the first 2 bytes. The string length includes the null-terminated.
CrInt32u GetValueSize() const	Get the total number of bytes of settable value set for values pointer.
CrInt8u* GetValues() const	Get the pointer of settable values. Details of the values are given in each device property in the Parameter description.
CrInt32u GetSetValueSize() const	It cannot be used. Reserved function.
CrInt8u* GetSetValues() const	It cannot be used. Reserved function.
CrInt32u GetDisplayValueSize() const	It cannot be used. Reserved function.
CrInt8u* GetDisplayValues() const	It cannot be used. Reserved function.
void SetCode(CrInt32u codes)	Set the CrDevicePropertyCode of the device property to update. Defined in CrDeviceProperty.h as CrDevicePropertyCode.
void SetValueType(CrDataType type)	Set the value type to update. Using CrDataType defined by CrDefines.h.
void SetCurrentValue(CrInt64u value)	Set the value to update. If CrDataType Array, only value that exist in the values pointer can be set. Details of the value are given in each device property in the Parameter description.
void SetCurrentStr(CrInt16u* str)	Set the string value. Valid when GetValueType () is CrDataType_STR. Specify the string length + 1 (for null-terminate) for the first 2 bytes. Set the string to the third byte and beyond.
