Examples with CompositeByteBuf org.apache.flink.shaded.netty4.io.netty.buffer.CompositeByteBuf used on opensource projects

Example 1 with CompositeByteBuf

use of org.apache.flink.shaded.netty4.io.netty.buffer.CompositeByteBuf in project elasticsearch by elastic.

the class Netty4UtilsTests method testToChannelBuffer.

public void testToChannelBuffer() throws IOException {
    BytesReference ref = getRandomizedBytesReference(randomIntBetween(1, 3 * PAGE_SIZE));
    ByteBuf buffer = Netty4Utils.toByteBuf(ref);
    BytesReference bytesReference = Netty4Utils.toBytesReference(buffer);
    if (ref instanceof ByteBufBytesReference) {
        assertEquals(buffer, ((ByteBufBytesReference) ref).toByteBuf());
    } else if (AbstractBytesReferenceTestCase.getNumPages(ref) > 1) {
        // we gather the buffers into a channel buffer
        assertTrue(buffer instanceof CompositeByteBuf);
    }
    assertArrayEquals(BytesReference.toBytes(ref), BytesReference.toBytes(bytesReference));
}

Example 2 with CompositeByteBuf

use of org.apache.flink.shaded.netty4.io.netty.buffer.CompositeByteBuf in project vert.x by eclipse.

the class Http2ConnectionBase method safeBuffer.

/**
   * Return a buffer from HTTP/2 codec that Vert.x can use:
   *
   * - if it's a direct buffer (coming likely from OpenSSL) : we get a heap buffer version
   * - if it's a composite buffer we do the same
   * - otherwise we increase the ref count
   */
static ByteBuf safeBuffer(ByteBuf buf, ByteBufAllocator allocator) {
    if (buf == Unpooled.EMPTY_BUFFER) {
        return buf;
    }
    if (buf.isDirect() || buf instanceof CompositeByteBuf) {
        if (buf.isReadable()) {
            ByteBuf buffer = allocator.heapBuffer(buf.readableBytes());
            buffer.writeBytes(buf);
            return buffer;
        } else {
            return Unpooled.EMPTY_BUFFER;
        }
    }
    return buf.retain();
}

Example 3 with CompositeByteBuf

use of org.apache.flink.shaded.netty4.io.netty.buffer.CompositeByteBuf in project netty by netty.

the class CoalescingBufferQueue method compose.

/**
     * Compose the current buffer with another.
     */
private ByteBuf compose(ByteBuf current, ByteBuf next) {
    if (current == null) {
        return next;
    }
    if (current instanceof CompositeByteBuf) {
        CompositeByteBuf composite = (CompositeByteBuf) current;
        composite.addComponent(true, next);
        return composite;
    }
    // Create a composite buffer to accumulate this pair and potentially all the buffers
    // in the queue. Using +2 as we have already dequeued current and next.
    CompositeByteBuf composite = channel.alloc().compositeBuffer(bufAndListenerPairs.size() + 2);
    composite.addComponent(true, current);
    composite.addComponent(true, next);
    return composite;
}

Example 4 with CompositeByteBuf

use of org.apache.flink.shaded.netty4.io.netty.buffer.CompositeByteBuf in project java-in-action by xinghalo.

the class CompositeTest method main.

public static void main(String[] args) {
    // 组合缓冲区
    CompositeByteBuf compBuf = Unpooled.compositeBuffer();
    ByteBuf header = Unpooled.buffer(8);
    header.writeBytes("aaaabbbb".getBytes());
    ByteBuf body = Unpooled.buffer(8);
    body.writeBytes("11112222".getBytes());
    // 添加ByteBuf到CompositeByteBuf
    compBuf.addComponents(header, body);
    System.out.println(compBuf.toString());
}

Example 5 with CompositeByteBuf

use of org.apache.flink.shaded.netty4.io.netty.buffer.CompositeByteBuf in project x-pipe by ctripcorp.

the class ArrayParser method getWriteByteBuf.

@Override
protected ByteBuf getWriteByteBuf() {
    int length = payload.length;
    CompositeByteBuf result = new CompositeByteBuf(UnpooledByteBufAllocator.DEFAULT, false, payload.length + 1);
    String prefix = String.format("%c%d\r\n", ASTERISK_BYTE, length);
    result.addComponent(Unpooled.wrappedBuffer(prefix.getBytes()));
    for (Object o : payload) {
        ByteBuf buff = ParserManager.parse(o);
        result.addComponent(buff);
    }
    result.setIndex(0, result.capacity());
    return result;
