详细描述

The OpenNI class is a static entry point to the library. It is used by every OpenNI 2.0 application to initialize the SDK and drivers to enable creation of valid device objects.

It also defines a listener class and events that enable for event driven notification of device connection, device disconnection, and device configuration changes.

In addition, it gives access to SDK version information and provides a function that allows you to wait for data to become available on any one of a list of streams (as opposed to waiting for data on one specific stream with functions provided by the VideoStream class)

成员函数说明

addDeviceConnectedListener()

static void org.openni.OpenNI.addDeviceConnectedListener ( DeviceConnectedListener  deviceListener )

inlinestatic

Add new device connected observer to OpenNI observers list

参数

deviceListener

object which implements DeviceConnectedListener.

addDeviceDisconnectedListener()

static void org.openni.OpenNI.addDeviceDisconnectedListener ( DeviceDisconnectedListener  deviceListener )

inlinestatic

Add new device connected observer to OpenNI observers list

参数

deviceListener

object which implements DeviceDisconnectedListener.

addDeviceStateChangedListener()

static void org.openni.OpenNI.addDeviceStateChangedListener ( DeviceStateChangedListener  deviceListener )

inlinestatic

Add new device connected observer to OpenNI observers list

参数

deviceListener

object which implements DeviceConnectedListener.

enumerateDevices()

static List<DeviceInfo> org.openni.OpenNI.enumerateDevices ( )

inlinestatic

Fills up an array of DeviceInfo DeviceInfo objects with devices that are available.

返回

deviceInfoList An array to be filled with devices.

getExtendedError()

static String org.openni.OpenNI.getExtendedError ( )

inlinestatic

Retrieves the calling thread's last extended error information. The last extended error information is maintained on a per-thread basis. Multiple threads do not overwrite each others last extended error information.

The extended error information is cleared on every call to an OpenNI method, so you should call this method immediately after a call to an OpenNI method which have failed.

返回

OpenNI error String

getVersion()

static Version org.openni.OpenNI.getVersion ( )

inlinestatic

This function return current OpenNI version

返回

the version of OpenNI

initialize()

static void org.openni.OpenNI.initialize ( )

inlinestatic

Initialize the library. This will load all available drivers, and see which devices are available It is forbidden to call any other method in OpenNI before calling initialize().

removeDeviceConnectedListener()

static void org.openni.OpenNI.removeDeviceConnectedListener ( DeviceConnectedListener  deviceListener )

inlinestatic

Remove device connected observer to OpenNI observers list

参数

deviceListener

object which implements DeviceConnectedListener.

removeDeviceDisconnectedListener()

static void org.openni.OpenNI.removeDeviceDisconnectedListener ( DeviceDisconnectedListener  deviceListener )

inlinestatic

Remove device connected observer to OpenNI observers list

参数

deviceListener

object which implements DeviceDisconnectedListener.

removeDeviceStateChangedListener()

static void org.openni.OpenNI.removeDeviceStateChangedListener ( DeviceStateChangedListener  deviceListener )

inlinestatic

Remove device state changed observer from OpenNI observers list

参数

deviceListener

object which implements DeviceConnectedListener.

setLogAndroidOutput()

static void org.openni.OpenNI.setLogAndroidOutput ( boolean  enabled )

inlinestatic

Configures if log entries will be printed to file

参数

enabled

Whether log entries should be printed to android log or not.

setLogAndroidOutputRedirect()

static void org.openni.OpenNI.setLogAndroidOutputRedirect ( boolean  enabled )

inlinestatic

Configures if log entries will be printed to and redirect.

参数

enabled

Whether log entries should be redirected after printing to Android logs.

setLogConsoleOutput()

static void org.openni.OpenNI.setLogConsoleOutput ( boolean  enabled )

inlinestatic

Configures if log entries will be printed to console

参数

enabled

Whether log entries should be printed to console or not.

setLogFileOutput()

static void org.openni.OpenNI.setLogFileOutput ( boolean  enabled )

inlinestatic

Configures if log entries will be printed to file

参数

enabled

Whether log entries should be printed to file or not.

setLogMinSeverity()

static void org.openni.OpenNI.setLogMinSeverity ( int  minSeverity )

inlinestatic

Set minimum severity for log entries

参数

minSeverity

Minimum severity to output

setLogOutputFolder()

static void org.openni.OpenNI.setLogOutputFolder ( String  path )

inlinestatic

Set the output folder for log files (if enabled)

参数

path	Path to write log files to.

shutdown()

static void org.openni.OpenNI.shutdown ( )

inlinestatic

Stop using the library. Unload all drivers, close all streams and devices. Once shutdown() was called, no other calls to OpenNI is allowed.

waitForAnyStream()

static int org.openni.OpenNI.waitForAnyStream ( List< VideoStream >  streams, int  timeout  ) throws TimeoutException

inlinestatic

Wait for a new frame from any of the streams provided. The function blocks until any of the streams has a new frame available, or the timeout has passed.

参数

streams	An list of streams to wait for.
timeout	A timeout before returning if no stream has new data. Default value is TIMEOUT_FOREVER.

返回

index of stream which received frame. In case it stop on timeout, function return -1.
