buffer

Constructor Details

AvailableNettyByteBody

public AvailableNettyByteBody(@NonNull
 @NonNull io.netty.buffer.ByteBuf buffer)

Method Details

empty

public static CloseableAvailableByteBody empty()

toByteBuf

@NonNull
public static @NonNull io.netty.buffer.ByteBuf toByteBuf(@NonNull
 @NonNull AvailableByteBody body)

createChecked

@NonNull
public static @NonNull CloseableByteBody createChecked(@NonNull
 @NonNull io.netty.channel.EventLoop loop,
 @NonNull
 @NonNull BodySizeLimits bodySizeLimits,
 @NonNull
 @NonNull io.netty.buffer.ByteBuf buf)

This is a wrapper around AvailableNettyByteBody(ByteBuf) with an extra body length check.

Parameters:

loop - The event loop for constructing StreamingNettyByteBody

bodySizeLimits - The body size limits to check

buf - The input buffer

Returns:

The body with the given input buffer, or a StreamingNettyByteBody with the appropriate content length error

peek

public io.netty.buffer.ByteBuf peek()

toInputStream

@NonNull
public @NonNull InputStream toInputStream()

Description copied from interface: ByteBody

Get this body as an InputStream.

This is a primary operation. After this operation, no other primary operation or ByteBody.split() may be done.

Specified by:

toInputStream in interface ByteBody

Returns:

The streamed bytes

length

public long length()

Description copied from interface: AvailableByteBody

The length in bytes of the body.

Specified by:

length in interface AvailableByteBody

Returns:

The length

See Also:

• ByteBody.expectedLength()

bufferFlow

@NonNull
public @NonNull ExecutionFlow<? extends CloseableAvailableByteBody> bufferFlow()

Description copied from interface: InternalByteBody

Variant of InternalByteBody.buffer() that uses the ExecutionFlow API for extra efficiency.

Specified by:

bufferFlow in interface InternalByteBody

Specified by:

bufferFlow in class NettyByteBody

Returns:

A flow that completes when all bytes are available

close

public void close()

Description copied from interface: CloseableByteBody

Clean up any resources held by this instance. See class documentation.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface CloseableByteBody

toByteBufPublisher

protected reactor.core.publisher.Flux<io.netty.buffer.ByteBuf> toByteBufPublisher()

toByteArray

public byte @NonNull [] toByteArray()

Description copied from interface: AvailableByteBody

Get this body as a byte array.

This is a primary operation. After this operation, no other primary operation or AvailableByteBody.split() may be done.

Specified by:

toByteArray in interface AvailableByteBody

Returns:

The bytes

toByteBuffer

@NonNull
public @NonNull ByteBuffer<?> toByteBuffer()

Description copied from interface: AvailableByteBody

Get this body as a ByteBuffer. Note that the buffer may be reference counted, and the caller must take care of releasing it.

This is a primary operation. After this operation, no other primary operation or AvailableByteBody.split() may be done.

Specified by:

toByteBuffer in interface AvailableByteBody

Returns:

The bytes

move

@NonNull
public @NonNull CloseableByteBody move()

Description copied from interface: ByteBody

Create a new CloseableByteBody with the same content but an independent lifecycle, claiming this body in the process.

This is a primary operation. After this operation, no other primary operation or ByteBody.split() may be done.

The purpose of this method is to move the data to a different component in an application, making clear that the receiving component claims ownership of the body. If the sending component then closes the original ByteBody for example, it will have no impact on the new CloseableByteBody that the receiver is working with.

Specified by:

move in interface ByteBody

Returns:

A new CloseableByteBody with the same content.

toString

@NonNull
public @NonNull String toString(Charset charset)

Description copied from interface: AvailableByteBody

Convert this body to a string with the given charset.

This is a primary operation. After this operation, no other primary operation or AvailableByteBody.split() may be done.

Specified by:

toString in interface AvailableByteBody

Parameters:

charset - The charset to convert the body

Returns:

The body as a string

split

@NonNull
public @NonNull CloseableAvailableByteBody split()

Description copied from interface: AvailableByteBody

For immediate buffers, backpressure is not relevant, so the backpressure modes passed to AvailableByteBody.split(SplitBackpressureMode) are ignored. You can use this method always.

Specified by:

split in interface AvailableByteBody

Specified by:

split in interface ByteBody

Returns:

A body with the same content as this one

• ByteBody.split()
