JvmMappedMemoryChunk

class JvmMappedMemoryChunk : MappedMemoryChunk(source)

JVM implementation of MappedMemoryChunk using FileChannel.map.

The mapped region is read-only and backed by the OS virtual memory subsystem. Pages are loaded on demand and evicted under memory pressure, so arbitrarily large regions can be mapped without consuming heap.
