Package io.activej.csp.file

Class ChannelFileReader

java.lang.Object

io.activej.async.process.AbstractAsyncCloseable

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

io.activej.csp.file.ChannelFileReader

All Implemented Interfaces:

io.activej.async.process.AsyncCloseable, io.activej.common.initializer.WithInitializer<ChannelFileReader>, ChannelSupplier<io.activej.bytebuf.ByteBuf>

public final class ChannelFileReader
extends AbstractChannelSupplier<io.activej.bytebuf.ByteBuf>
implements io.activej.common.initializer.WithInitializer<ChannelFileReader>

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