Examples of TempVars

com.jme3.util.TempVars
Temporary variables assigned to each thread. Engine classes may access these temp variables with TempVars.get(), all retrieved TempVars instances must be returned via TempVars.release(). This returns an available instance of the TempVar class ensuring this particular instance is never used elsewhere in the mean time.
