El método limit() de java.nio.DoubleBuffer Class se usa para modificar el límite de este DoubleBuffer. Este método toma el límite a establecer como parámetro y lo establece como el nuevo límite de este búfer. Si la marca de este Buffer ya está definida y es mayor que el nuevo límite especificado, entonces este nuevo límite no se establece y se descarta.
Sintaxis:
public final DoubleBuffer limit(int newLimit)
Valor devuelto: este método devuelve este búfer después de establecer el nuevo límite especificado como el nuevo límite de este búfer.
A continuación se muestran los ejemplos para ilustrar el método limit():
Ejemplos 1:
// Java program to demonstrate
// limit() method
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// defining and allocating DoubleBuffer
// using allocate() method
DoubleBuffer doubleBuffer
= DoubleBuffer.allocate(4);
// put double value in doubleBuffer
// using put() method
doubleBuffer.put(20.5);
doubleBuffer.put(30.5);
// print the double buffer
System.out.println("DoubleBuffer before "
+ "setting buffer's limit: "
+ Arrays.toString(
doubleBuffer.array())
+ "\nPosition: "
+ doubleBuffer.position()
+ "\nLimit: "
+ doubleBuffer.limit());
// Limit the doubleBuffer
// using limit() method
doubleBuffer.limit(1);
// print the double buffer
System.out.println("\nDoubleBuffer after "
+ "setting buffer's limit: "
+ Arrays.toString(
doubleBuffer.array())
+ "\nPosition: "
+ doubleBuffer.position()
+ "\nLimit: "
+ doubleBuffer.limit());
}
}
DoubleBuffer before setting buffer's limit: [20.5, 30.5, 0.0, 0.0] Position: 2 Limit: 4 DoubleBuffer after setting buffer's limit: [20.5, 30.5, 0.0, 0.0] Position: 1 Limit: 1
Ejemplos 2:
// Java program to demonstrate
// limit() method
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// defining and allocating DoubleBuffer
// using allocate() method
DoubleBuffer doubleBuffer
= DoubleBuffer.allocate(5);
// put double value in DoubleBuffer
// using put() method
doubleBuffer.put(20.5);
doubleBuffer.put(30.5);
doubleBuffer.put(40.5);
// mark will be going to
// discarded by limit()
doubleBuffer.mark();
// print the double buffer
System.out.println("DoubleBuffer before "
+ "setting buffer's limit: "
+ Arrays.toString(
doubleBuffer.array())
+ "\nPosition: "
+ doubleBuffer.position()
+ "\nLimit: "
+ doubleBuffer.limit());
// Limit the doubleBuffer
// using limit() method
doubleBuffer.limit(4);
// print the double buffer
System.out.println("\nDoubleBuffer before "
+ "setting buffer's limit: "
+ Arrays.toString(
doubleBuffer.array())
+ "\nPosition: "
+ doubleBuffer.position()
+ "\nLimit: "
+ doubleBuffer.limit());
}
}
DoubleBuffer before setting buffer's limit: [20.5, 30.5, 40.5, 0.0, 0.0] Position: 3 Limit: 5 DoubleBuffer before setting buffer's limit: [20.5, 30.5, 40.5, 0.0, 0.0] Position: 3 Limit: 4
