Member Function Documentation

getAdapters()

List< BTAdapter > org.direct_bt.BTManager.getAdapters

(

)

Returns a list of BluetoothAdapters available in the system.

Returns

A list of BluetoothAdapters available in the system

Implemented in jau.direct_bt.DBTManager.

Here is the caller graph for this function:

getAdapter()

BTAdapter org.direct_bt.BTManager.getAdapter

(

final int

dev_id

)

Returns the BluetoothAdapter matching the given dev_id or null if not found.

The adapters internal device id is constant across the adapter lifecycle, but may change after its destruction.

Parameters

dev_id

the internal temporary adapter device id

Since

2.0.0

Implemented in jau.direct_bt.DBTManager.

setDefaultAdapter()

boolean org.direct_bt.BTManager.setDefaultAdapter

(

BTAdapter

adapter

)

Sets a default adapter to use for discovery.

Returns

TRUE if the device was set @implNote not implemented for jau.direct_bt

Implemented in jau.direct_bt.DBTManager.

getDefaultAdapter()

BTAdapter org.direct_bt.BTManager.getDefaultAdapter

(

)

Gets the default adapter to use for discovery.

The default adapter is either the first powered BTAdapter, or function returns nullptr if none is enabled.

Returns

the used default adapter

Implemented in jau.direct_bt.DBTManager.

addChangedAdapterSetListener()

void org.direct_bt.BTManager.addChangedAdapterSetListener

(

final ChangedAdapterSetListener

l

)

Add the given ChangedAdapterSetListener to this manager.

When a new callback is added, all available adapter's will be reported as added, this allows a fully event driven workflow.

The callback is performed on a dedicated thread, allowing the user to perform complex operations.

Since

2.0.0

Implemented in jau.direct_bt.DBTManager.

Here is the caller graph for this function:

removeChangedAdapterSetListener()

int org.direct_bt.BTManager.removeChangedAdapterSetListener

(

final ChangedAdapterSetListener

l

)

Remove the given ChangedAdapterSetListener from this manager.

Parameters

l	the to be removed element

Returns

the number of removed elements

Since

2.0.0

Implemented in jau.direct_bt.DBTManager.

Here is the caller graph for this function:

removeAllChangedAdapterSetListener()

int org.direct_bt.BTManager.removeAllChangedAdapterSetListener

(

)

Remove all added ChangedAdapterSetListener entries from this manager.

Returns

the number of removed elements

Since

2.7.0

Implemented in jau.direct_bt.DBTManager.

shutdown()

void org.direct_bt.BTManager.shutdown

(

)

Release the native memory associated with this object and all related Bluetooth resources.

The object should not be used following a call to close

Shutdown method is intended to allow a clean Bluetooth state at program exist.

Implemented in jau.direct_bt.DBTManager.
