IrOBEXControl

public final class IrOBEXControl extends Object
Performs the IrOBEX initialization, handles the device hint bits state, and responsible for device/service discovery process.

Fields Summary
Constructors Summary
public IrOBEXControl()
Default constructor.
Methods Summary
public IrOBEXConnectioncreateClientConnection(int hints, java.lang.String[] ias)
Attempts to connect to the first device matches the criteria specified (hint bits and IAS list). Cached devices are attempted first. If failed, discovery process is initiated to update the cache, followed by another connection attempt to a cached device. The procedure repeats until the connection is established, or timout occurs.

param
hints hint bits required to be set on the device
param
ias services required to be provided by the device
return
IrOBEXConnection object
exception
IOException if something goes wrong
