put

public void put(byte c)

Description copied from interface: OStream

For `put(byte c)` we will generate a native method:

 public class OStreamImpl{
     public void put(byte c) { nativePut(getAddress(), c); }
     native void nativePut(long address, byte c);
 }
 

In the generated JNI cxx file:

 void Java_xxx_nativePut(JNIEnv*, jclass, jlong address, jbytec)
 {
      std::ostream* obj = reinterpret_cast<std::ostream*>(address);
      obj->put(c);
 }
 

Specified by:

put in interface OStream

Parameters:

c - byte

nativePut

public static void nativePut(long ptr,
                             byte c0)
