Package org.opensearch.common.io.stream

Classes for streaming objects from one OpenSearch node to another over its binary internode protocol.

Interface Summary

Interface	Description
NamedWriteable	A Writeable object identified by its name.
VersionedNamedWriteable	A NamedWriteable that has a minimum version associated with it.
Writeable	Implementers can be written to a StreamOutput and read from a StreamInput.
Writeable.Reader<V>	Reference to a method that can read some object from a stream.
Writeable.Writer<V>	Reference to a method that can write some object to a StreamOutput.

Class Summary

Class	Description
ByteBufferStreamInput
BytesStream
BytesStreamOutput	A @link StreamOutput that uses BigArrays to acquire pages of bytes, which avoids frequent reallocation & copying of the internal data.
DataOutputStreamOutput
DelayableWriteable<T extends Writeable>	A holder for Writeables that delays reading the underlying object on the receiving end.
DelayableWriteable.Serialized<T extends Writeable>	A Writeable stored in serialized form.
FilterStreamInput	Wraps a StreamInput and delegates to it.
InputStreamStreamInput
NamedWriteableAwareStreamInput	Wraps a StreamInput and associates it with a NamedWriteableRegistry
NamedWriteableRegistry	A registry for Writeable.Reader readers of NamedWriteable.
NamedWriteableRegistry.Entry	An entry in the registry, made up of a category class and name, and a reader for that category class.
OutputStreamStreamOutput
ReleasableBytesStreamOutput	An bytes stream output that allows providing a BigArrays instance expecting it to require releasing its content (BytesStreamOutput.bytes()) once done.
StreamInput	A stream from this node to another node.
StreamOutput	A stream from another node to this node.

Exception Summary

Exception	Description
NotSerializableExceptionWrapper	This exception can be used to wrap a given, not serializable exception to serialize via StreamOutput.writeException(Throwable).
