Method Detail

newInstance

public static BinaryReader newInstance(java.nio.ByteBuffer buffer,
                                       boolean bufferIsImmutable)

Creates a new reader using the given buffer as input.

Parameters:

buffer - the input buffer. The buffer (including position, limit, etc.) will not be modified. To increment the buffer position after the read completes, use the value returned by getTotalBytesRead().

bufferIsImmutable - if true the reader assumes that the content of buffer will never change and any allocated ByteString instances will by directly wrap slices of buffer.

Returns:

the reader

getTotalBytesRead

public abstract int getTotalBytesRead()

Returns the total number of bytes read so far from the input buffer.

shouldDiscardUnknownFields

public boolean shouldDiscardUnknownFields()

Specified by:

shouldDiscardUnknownFields in interface Reader
