Constructor Details

ObserveViaCasRequest

public ObserveViaCasRequest(Duration timeout,
 CoreContext ctx,
 CollectionIdentifier collectionIdentifier,
 RetryStrategy retryStrategy,
 String key,
 boolean active,
 int replica)

Method Details

replica

public int replica()

active

public boolean active()

encode

public com.couchbase.client.core.deps.io.netty.buffer.ByteBuf encode(com.couchbase.client.core.deps.io.netty.buffer.ByteBufAllocator alloc,
 int opaque,
 KeyValueChannelContext ctx)

Description copied from interface: KeyValueRequest

Encode this request with the given allocator and opaque.

Parameters:

alloc - the allocator where to grab the buffers from.

opaque - the opaque value to use.

ctx - more encode context.

Returns:

the encoded request as a ByteBuf.

decode

public ObserveViaCasResponse decode(com.couchbase.client.core.deps.io.netty.buffer.ByteBuf response,
 KeyValueChannelContext ctx)

Description copied from interface: KeyValueRequest

Decode the encoded response into its message representation.

Parameters:

response - the response to decode.

Returns:

the decoded response as the generic type R.

idempotent

public boolean idempotent()

Description copied from interface: Request

Returns if the given request is idempotent or not.

By default, this method always returns false for data consistency reasons. Only specific idempotent operations should override this default since it impacts retry handling quite a bit. DO NOT SET THIS TO TRUE ON MUTATING OPERATIONS!

Returns:

true if idempotent.

name

public String name()

Description copied from interface: Request

The unique name of the request, usually related to the type but not necessarily.

The default implementation is derived from the class name (i.e. FooRequest returns foo), but if that does not match up it should be overridden in the actual class.

Returns:

the name of the request type.
