@NotNull
default <T> T bytesMethodWriter(@NotNull
                                         @NotNull Class<T> tClass,

                                  throws IllegalArgumentException

Proxy an interface so each message called is written to a file for replay.

Parameters:

tClass - primary interface

additional - any additional interfaces

Returns:

a proxy which implements the primary interface (additional interfaces have to be cast)

Throws:

NullPointerException - if the provided tClass is null

net.openhft.chronicle.core.io.ClosedIllegalStateException - if this BytesOut has been previously released

IllegalArgumentException

writeMarshallableLength16

void writeMarshallableLength16(WriteBytesMarshallable marshallable)
                        throws IllegalArgumentException,
                               BufferOverflowException,
                               IllegalStateException,

Throws:

IllegalArgumentException

BufferOverflowException

IllegalStateException

BufferUnderflowException

writeObject

default void writeObject(Class componentType,
                         Object obj)
                  throws IllegalArgumentException,
                         BufferOverflowException,
                         ArithmeticException,
                         IllegalStateException,
                         BufferUnderflowException

Write a limit set of writeObject types.

Parameters:

componentType - expected.

obj - of componentType

Throws:

IllegalArgumentException

BufferOverflowException

ArithmeticException

IllegalStateException

BufferUnderflowException

start

default long start()

Returns:

The smallest position allowed in this buffer.

capacity

default long capacity()

Returns:

the highest limit allowed for this buffer.

readPosition

default long readPosition()

Returns the read position.

The read position is start() <= readPosition() && readPosition() <= readLimit() && readPosition < safeLimit()

If the resource is closed, the returned value is unspecified.

Returns:

position to read from.

writePosition

default long writePosition()

Returns the write position. The write position is readPosition() <= writePosition() && writePosition() <= writeLimit()

If the resource is closed, the returned value is unspecified.

Returns:

position to write to.

lengthWritten

default long lengthWritten(long startPosition)

Typically this calculates the difference however for HexDumpBytes it's not as simple.

If the resource is closed, the returned value is unspecified.

Parameters:

startPosition - to compare against

Returns:

the length from the startPosition

readRemaining

default long readRemaining()

Returns the remaining bytes that can be read.

If the resource is closed, the returned value is unspecified.

Returns:

How many more bytes can we read.

realReadRemaining

default long realReadRemaining()

If the resource is closed, the returned value is unspecified.

Returns:

how much can be safely read directly.

writeRemaining

default long writeRemaining()

If the resource is closed, the returned value is unspecified.

Returns:

How many more bytes can we written.

realWriteRemaining

default long realWriteRemaining()

If the resource is closed, the returned value is unspecified.

Returns:

writeRemaining with resize

readLimit

default long readLimit()

If the resource is closed, the returned value is unspecified.

Returns:

the highest offset or position allowed for this buffer.

writeLimit

default long writeLimit()

Returns the write limit.

If the resource is closed, the returned value is unspecified.

Returns:

the write limit
