El método rewind() de java.nio.ShortBuffer Class se utiliza para rebobinar este búfer. Al rebobinar este Buffer, se toman las siguientes acciones:
- La posición actual se establece en cero
- la marca se descarta, si la hay, pero el valor de la marca no cambia.
Sintaxis:
public ShortBuffer rewind()
Parámetro: Este método no acepta ningún parámetro.
Valor devuelto: este método devuelve este búfer .
A continuación se muestran los ejemplos para ilustrar el método rewind():
Ejemplos 1:
// Java program to demonstrate
// rewind() method
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// defining and allocating ShortBuffer
// using allocate() method
ShortBuffer shortBuffer
= ShortBuffer.allocate(4);
// put short value in shortBuffer
// using put() method
shortBuffer.put((short)10);
shortBuffer.put((short)20);
// print the short buffer
System.out.println(
"Buffer before operation: "
+ Arrays.toString(
shortBuffer.array())
+ "\nPosition: "
+ shortBuffer.position()
+ "\nLimit: "
+ shortBuffer.limit());
// rewind the Buffer
// using rewind() method
shortBuffer.rewind();
// print the shortbuffer
System.out.println(
"\nBuffer after operation: "
+ Arrays.toString(
shortBuffer.array())
+ "\nPosition: "
+ shortBuffer.position()
+ "\nLimit: "
+ shortBuffer.limit());
}
}
Producción:
Buffer before operation: [10, 20, 0, 0] Position: 2 Limit: 4 Buffer after operation: [10, 20, 0, 0] Position: 0 Limit: 4
Ejemplos 2:
// Java program to demonstrate
// rewind() method
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// defining and allocating ShortBuffer
// using allocate() method
ShortBuffer shortBuffer
= ShortBuffer.allocate(5);
// put short value in shortBuffer
// using put() method
shortBuffer.put((short)10);
shortBuffer.put((short)20);
shortBuffer.put((short)30);
// mark will be going to discarded by rewind()
shortBuffer.mark();
// print the buffer
System.out.println(
"Buffer before operation: "
+ Arrays.toString(
shortBuffer.array())
+ "\nPosition: "
+ shortBuffer.position()
+ "\nLimit: "
+ shortBuffer.limit());
// Rewind the Buffer
// using rewind() method
shortBuffer.rewind();
// print the buffer
System.out.println(
"\nBuffer after operation: "
+ Arrays.toString(
shortBuffer.array())
+ "\nPosition: "
+ shortBuffer.position()
+ "\nLimit: "
+ shortBuffer.limit());
}
}
Producción:
Buffer before operation: [10, 20, 30, 0, 0] Position: 3 Limit: 5 Buffer after operation: [10, 20, 30, 0, 0] Position: 0 Limit: 5
