public TestMemory()

Creates a new instance of TestMemory

Method Detail

init_Runtime

protected final void init_Runtime()

Initialises _Runtime

getTotalFreeMemory

public long getTotalFreeMemory()

For returning the total free memory

• ( _Runtime.freeMemory() + ( _Runtime.maxMemory() - _Runtime.totalMemory() ) )

Even if this is zero then the JVM may be able to allocate memory in reserves?

Returns:

The TotalFreeMemory available as calculated from _Runtime. If the returned value is lower than a minimum required to call a method then probably best to swap some data.
