Description copied from interface: ThreadIDProvider

Return s the current thread id

Specified by:

getThreadID in interface ThreadIDProvider

Returns:

convertNativeThreadIDToPositiveInteger

public static int convertNativeThreadIDToPositiveInteger(long nativeThreadID)

Converts a native thread id to a positive integer Thread.currentThread().getId()

Thread.currentThread().getId() returns a long value. The Beacon protocol requires the thread id to be a positive integer value. By using the xor operation between higher and lower 32 bits of the long value we get an integer value. The returned integer can be negative though. Therefore the most significant bit is forced to '0' by a bitwise-and operation with an integer where all bits except for the most significant bit are set to '1'.

Parameters:

nativeThreadID - the native thread id returned by

Returns:

a positive integer value calculated from the native thread id
