read(InputStream input)
Read length-prefixed data from the specified input stream and return a
newly allocated byte buffer that holds the data.
|
int |
readSOF(InputStream input)
Read and validate the length-prefixed start of frame from the specified
input stream and return the decoded length of the expected message.

void |
setMaxBufferSize(int maxBufferSize)
Set the current maximum buffer size supported by this byte transfer.
|
void |
write(OutputStream output,
byte[] data)
Write the given byte buffer to the specified output stream using the
length-prefixed transfer.
|
void |
write(OutputStream output,
byte[] data,
int offset,
int length)
Write the given section of a byte buffer to the specified output stream
using the length-prefixed transfer.
|
void |
write(OutputStream output,
Writable w)
Write the given writable to the specified output stream using the
length-prefixed transfer.
|
int |
writeSOF(OutputStream output,
int length)
Write a start of frame of the length-prefixed message.
