Example 1 with WriteBytesEvent

use of org.ballerinalang.nativeimpl.io.events.bytes.WriteBytesEvent in project ballerina by ballerina-lang.

the class IOUtils method write.

 *
 * @param channel  channel which will be used to write bytes.
 * @param content  content which will be written.
 * @param offset   the offset which will be set to write bytes.
 * @param context  context of the native function call.
 * @param function callback function which should be called upon completion.
