Class ChannelFileReader

java.lang.Object

io.activej.reactor.AbstractReactive

io.activej.reactor.ImplicitlyReactive

io.activej.async.process.AbstractAsyncCloseable

io.activej.csp.supplier.AbstractChannelSupplier<io.activej.bytebuf.ByteBuf>

io.activej.csp.file.ChannelFileReader

All Implemented Interfaces:

io.activej.async.process.AsyncCloseable, ChannelSupplier<io.activej.bytebuf.ByteBuf>, io.activej.reactor.Reactive

public final class ChannelFileReader
extends AbstractChannelSupplier<io.activej.bytebuf.ByteBuf>

This supplier allows you to asynchronously read binary data from a file.
