Class Memory

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable
    Direct Known Subclasses:
    StringArray


    public class Memory
    extends Pointer
    implements java.io.Closeable
    A Pointer to memory obtained from the native heap via a call to malloc.

    In some cases it might be necessary to use memory obtained from malloc. For example, Memory helps accomplish the following idiom:

            void *buf = malloc(BUF_LEN * sizeof(char));
            call_some_function(buf);
            free(buf);
