Description

The list of methods to do ByteBuffer Clear are organized into topic(s).

Method

voidclear(ByteBuffer b)
clear 
b.reset(); 
b.limit(b.capacity());
voidclear(ByteBuffer buffer)
Clear the buffer to be empty in flush mode. 
if (buffer != null) {
    buffer.position(0);
    buffer.limit(0);
voidclear(ByteBuffer buffer, int position, int length, byte filler)
clear 
assert buffer != null;
prepare(buffer, position, length);
fill(buffer, position, buffer.limit(), filler);
voidclear(ByteBuffer[] buffers)
clear 
if (buffers == null) {
    return;
for (ByteBuffer buffer : buffers) {
    if (buffer != null) {
        buffer.clear();
voidclearAll(ByteBuffer[] buffers)
Convenience method to clear array of buffers. 
for (int i = buffers.length; i-- > 0;)
    buffers[i].clear();
ByteBufferclearAndEnsureCapacity(ByteBuffer buffer, int elements)
Ensure the buffer's capacity is large enough to hold a given number of elements. 
if (buffer == null || buffer.capacity() < elements) {
    buffer = ByteBuffer.allocate(elements);
} else {
    buffer.clear();
return buffer;
voidclearRemaining(ByteBuffer buffer)
Sets all bits in the given remaining byte range to 0. 
if (!buffer.hasRemaining()) {
    return;
int pos = buffer.position();
clearRange(buffer, pos, pos + buffer.remaining());
voidclearRemainingFrame(ByteBuffer buffer, int position)
clear Remaining Frame 
buffer.array()[position] = 0;
voidclearString(ByteBuffer buffer)
clear String 
byte[] data = new byte[buffer.capacity()];
for (int i = 0; i < data.length; i++) {
    data[i] = '0';
buffer.clear();
buffer.put(data);
buffer.clear();
booleanfillBuffer(ReadableByteChannel channel, ByteBuffer buf, boolean clear)
fill Buffer 
if (clear) {
    buf.clear();
while (true) {
    int cnt = channel.read(buf);
    if (cnt < 0) {
        return false;
    if (buf.position() == buf.capacity()) {
        break;
return true;
