ByteReadPacketPlatformBase

Close input including the underlying source. All pending bytes will be discarded. It is not recommended to invoke it with read operations in-progress concurrently.

Discards at most n bytes

Discard at most n bytes

Discards exactly n bytes or fails with EOFException

Copy available bytes to the specified buffer but keep them available. The underlying implementation could trigger bytes population from the underlying source and block until any bytes available.

Try to copy at least min but up to max bytes to the specified destination buffer from this input skipping offset bytes. If there are not enough bytes available to provide min bytes after skipping offset bytes then it will trigger the underlying source reading first and after that will simply copy available bytes even if EOF encountered so min is not a requirement but a desired number of bytes. It is safe to specify max greater than the destination free space. min shouldn't be bigger than the destination free space. This function could trigger the underlying source reading that may lead to blocking I/O. It is allowed to specify too big offset so in this case this function will always return 0 after prefetching all underlying bytes but note that it may lead to significant memory consumption. This function usually copy more bytes than min (unless max = min) but it is not guaranteed. When 0 is returned with offset = 0 then it makes sense to check endOfInput.

Read the next upcoming byte

Read exactly length bytes to dst array at specified offset

Read a string at last min and at most max characters length

Read at least min and at most max characters and append them to out

Read a string exactly exactCharacters length

Read exactly exactCharacters characters and append them to out

Release packet. After this function invocation the packet becomes empty. If it has been copied via ByteReadPacket.copy then the copy should be released as well.

Returns next byte (unsigned) or -1 if no more bytes available

It is true when it is known that no more bytes will be available. When it is false then this means that it is not known yet or there are available bytes. Please note that false value doesn't guarantee that there are available bytes so readByte() may fail.

true if no bytes available for read

Number of bytes available for read
