Class Buffer

java.lang.Object

io.vertx.rxjava3.core.buffer.Buffer

All Implemented Interfaces:

io.vertx.core.shareddata.impl.ClusterSerializable, io.vertx.lang.rx.RxDelegate

public class Buffer
extends Object
implements io.vertx.lang.rx.RxDelegate, io.vertx.core.shareddata.impl.ClusterSerializable

Most data is shuffled around inside Vert.x using buffers.

A buffer is a sequence of zero or more bytes that can read from or written to and which expands automatically as necessary to accommodate any bytes written to it. You can perhaps think of a buffer as smart byte array.

Please consult the documentation for more information on buffers.

NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.

                        String enc)

Sets the bytes at position pos in the Buffer to the value of str encoded in encoding enc.

The buffer will expand as necessary to accommodate any value written.

Parameters:

pos -

str -

enc -

Returns:

length

public int length()

Returns the length of the buffer, measured in bytes. All positions are indexed from zero.

Returns:

copy

public Buffer copy()

Returns a copy of the entire Buffer.

Returns:

slice

public Buffer slice()

Returns a slice of this buffer. Modifying the content of the returned buffer or this buffer affects each other's content while they maintain separate indexes and marks.

Returns:

slice

public Buffer slice(int start,
                    int end)

Returns a slice of this buffer. Modifying the content of the returned buffer or this buffer affects each other's content while they maintain separate indexes and marks.

Parameters:

start -

end -

Returns:

buffer

public static Buffer buffer(byte[] bytes)

Create a new buffer from a byte[]. The byte[] will be copied to form the buffer.

Parameters:

bytes - the byte array

Returns:

the buffer

buffer

@Deprecated
public static Buffer buffer(ByteBuf byteBuf)

Deprecated.

Create a new buffer from a Netty ByteBuf. Note that the returned buffer is backed by given Netty ByteBuf, so changes in the returned buffer are reflected in given Netty ByteBuf, and vice-versa.

For example, both buffers in the code below share their data:

   Buffer src = Buffer.buffer();
   Buffer clone = Buffer.buffer(src.getByteBuf());
 

Parameters:

byteBuf - the Netty ByteBuf

Returns:

the buffer

toString

public String toString(Charset enc)

Returns a String representation of the Buffer with the encoding specified by enc

Parameters:

enc -

Returns:

getBytes

public byte[] getBytes()

Returns a copy of the entire Buffer as a byte[]

Returns:

getBytes

public byte[] getBytes(int start,
                       int end)

Returns a copy of a sub-sequence the Buffer as a byte[] starting at position start and ending at position end - 1

Parameters:

start -

end -

Returns:

getBytes

public Buffer getBytes(byte[] dst)

Transfers the content of the Buffer into a byte[].

Parameters:

dst - the destination byte array

Returns:

getBytes

public Buffer getBytes(byte[] dst,
                       int dstIndex)

Transfers the content of the Buffer into a byte[] at the specific destination.

Parameters:

dst - the destination byte array

dstIndex -

Returns:

getBytes

public Buffer getBytes(int start,
                       int end,
                       byte[] dst)

Transfers the content of the Buffer starting at position start and ending at position end - 1 into a byte[].

Parameters:

start -

end -

dst - the destination byte array

Returns:

getBytes

public Buffer getBytes(int start,
                       int end,
                       byte[] dst,
                       int dstIndex)

Transfers the content of the Buffer starting at position start and ending at position end - 1 into a byte[] at the specific destination.

Parameters:

start -

end -

dst - the destination byte array

dstIndex -

Returns:

appendBytes

public Buffer appendBytes(byte[] bytes)

Appends the specified byte[] to the end of the Buffer. The buffer will expand as necessary to accommodate any bytes written.

Returns a reference to this so multiple operations can be appended together.

Parameters:

bytes -

Returns:

appendBytes

public Buffer appendBytes(byte[] bytes,
                          int offset,
                          int len)

Appends the specified number of bytes from byte[] to the end of the Buffer, starting at the given offset. The buffer will expand as necessary to accommodate any bytes written.

Returns a reference to this so multiple operations can be appended together.

Parameters:

bytes -

offset -

len -

Returns:

setBytes

public Buffer setBytes(int pos,
                       ByteBuffer b)

Sets the bytes at position pos in the Buffer to the bytes represented by the ByteBuffer b.

The buffer will expand as necessary to accommodate any value written.

Parameters:

pos -

b -

Returns:

setBytes

public Buffer setBytes(int pos,
                       byte[] b)
