public class NotModified
extends BasicHttpResponse<NotModified>

Represents an HTTP 304 Not Modified response.

Constructor Details

NotModified

public NotModified()

Constructor.

NotModified

public NotModified(HttpResponse response)

Constructor.

This is the constructor used when parsing an HTTP response.

Parameters:

response - The HTTP response to copy from. Must not be null.

Throws:

IllegalArgumentException - If HTTP response status code does not match what was expected.

NotModified

public NotModified(NotModified copyFrom)

Copy constructor.

Parameters:

copyFrom - The bean to copy from. Must not be null.

Method Details

copy

public NotModified copy()

Creates a builder for this class initialized with the contents of this bean.

Returns:

A new builder bean.

unmodifiable

public NotModified unmodifiable()

Description copied from class: BasicHttpResponse

Returns an unmodifiable snapshot of this bean.

The returned instance is a point-in-time copy of the leaf's nested Unmodifiable type; any attempt to set a property on it throws an UnsupportedOperationException. This method is idempotent: if this bean is already unmodifiable it returns itself rather than taking another snapshot. The receiver is left unchanged (and still modifiable unless it was already unmodifiable).

Specified by:

unmodifiable in class BasicHttpResponse<NotModified>

Returns:

An unmodifiable snapshot of this bean, or this bean if it is already unmodifiable.
