Method Detail

clearAndPad

@NotNull
B clearAndPad(long length)
                throws BufferOverflowException

Clear a buffer, with a given padding to allow for prepending later. clearAndPad(0) is the same as clear()

Parameters:

length - to pad

Returns:

this

Throws:

BufferOverflowException - if the length > capacity() - start()

prepend

@NotNull
default B prepend(long value)
                    throws BufferOverflowException

Prepends a long in decimal, this method moves the readPosition() backwards.

Note: it moves the readPosition not the writePosition / readLimit

Parameters:

value - to prepend as text.

Returns:

this

Throws:

BufferUnderflowException - if the capacity of the underlying buffer was exceeded

net.openhft.chronicle.core.io.IORuntimeException - if an error occurred while attempting to resize the underlying buffer

BufferOverflowException

prewrite

@NotNull
B prewrite(byte[] bytes)

Write backward in binary a byte

Note: it moves the readPosition not the writePosition / readLimit

Parameters:

bytes - to prepend to.

prewrite

@NotNull
B prewrite(BytesStore bytes)

Write backward in binary a byte

Note: it moves the readPosition not the writePosition / readLimit

Parameters:

bytes - to prepend to.

prewriteByte

@NotNull
B prewriteByte(byte b)

Write backward in binary a byte

Note: it moves the readPosition not the writePosition / readLimit

Parameters:

b - byte to prepend to.

prewriteShort

@NotNull
B prewriteShort(short i)

Write backward in binary a 2 byte int

Note: it moves the readPosition not the writePosition / readLimit

Parameters:

i - short to prepend to.

prewriteInt

@NotNull
B prewriteInt(int i)

Write backward in binary a 4 byte int

Note: it moves the readPosition not the writePosition / readLimit

Parameters:

i - integer to prepend to.

prewriteLong

@NotNull
B prewriteLong(long l)

Write backward in binary an 8 byte long

Note: it moves the readPosition not the writePosition / readLimit

Parameters:

l - long to prepend to.
