El método limit() de java.nio.CharBuffer Class se usa para establecer el límite de este búfer. Si la posición es mayor que el nuevo límite, se establece en el nuevo límite. Si la marca está definida y es mayor que el nuevo límite, se descarta.
Sintaxis:
public CharBuffer limit(int newLimit)
Valor devuelto: este método devuelve 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 CharBuffer
// using allocate() method
CharBuffer charBuffer = CharBuffer.allocate(4);
// append char value in CharBuffer
// using char() method
charBuffer.append('a');
charBuffer.append('b');
// print the char buffer
System.out.println("CharBuffer before "
+ "setting buffer's limit: "
+ Arrays.toString(
charBuffer.array())
+ "\nPosition: "
+ charBuffer.position()
+ "\nLimit: "
+ charBuffer.limit());
// Limit the CharBuffer
// using limit() method
charBuffer.limit(1);
// print the char buffer
System.out.println("CharBuffer before "
+ "setting buffer's limit: "
+ Arrays.toString(
charBuffer.array())
+ "\nPosition: "
+ charBuffer.position()
+ "\nLimit: "
+ charBuffer.limit());
}
}
Producción:
CharBuffer before setting buffer's limit: [a, b,, ] Position: 2 Limit: 4 CharBuffer after setting buffer's limit: [a, b,, ] 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 CharBuffer
// using allocate() method
CharBuffer charBuffer
= CharBuffer.allocate(5);
// append char value in CharBuffer
// using char() method
charBuffer.append('a');
charBuffer.append('b');
charBuffer.append('c');
// mark will be going to discarded by limit()
charBuffer.mark();
// print the char buffer
System.out.println("CharBuffer before "
+ "setting buffer's limit: "
+ Arrays.toString(
charBuffer.array())
+ "\nPosition: "
+ charBuffer.position()
+ "\nLimit: "
+ charBuffer.limit());
// Limit the charBuffer
// using limit() method
charBuffer.limit(4);
// print the char buffer
System.out.println("CharBuffer before "
+ "setting buffer's limit: "
+ Arrays.toString(
charBuffer.array())
+ "\nPosition: "
+ charBuffer.position()
+ "\nLimit: "
+ charBuffer.limit());
}
}
Producción:
CharBuffer before setting buffer's limit: [a, b, c,, ] Position: 3 Limit: 5 CharBuffer after setting buffer's limit: [a, b, c,, ] Position: 3 Limit: 4
