Examples of MemBuffersForBytes

com.fasterxml.util.membuf.MemBuffersForBytes
Factory for creating {@link ChunkyBytesMemBuffer}s and {@link StreamyBytesMemBuffer}s, memory buffers that contain byte sequences.
Default segments use {@link java.nio.ByteBuffer} for store byte sequences;this can be overridden by specifying alternate {@link SegmentAllocator} implementation.
