Method Detail

getJNAPointer

public static com.sun.jna.Pointer getJNAPointer(long pAddress)

Gets JNA pointer given a native address. Important: there is no way to keep a reference of the parent object in a JNA Pointer. Holding the 'long' value of the pointer is no garantee that the corresponding buffer will not be deleted (opposite of malloc) if the holding object is garbage collected...

Parameters:

pAddress - address

Returns:

JNA pointer

getJNAPointer

public static com.sun.jna.Pointer getJNAPointer(ContiguousMemoryInterface pContiguousMemory)

Returns a JNA Pointer Note: JNA memory have a BIG problem: the corresponding off-heap memory is not freed when garbage collected... are not freed when the It is a real problem.... So it is much better to allocate memory with CoreMem and then get a JNA pointer, instead of allocating on the JNA side...

Parameters:

pContiguousMemory - contiguous memory object

Returns:

JNA pointer
