Detailed Description

Container representing a remote request.

The real name of a S3Container is the actual remote request. When the access method is called the remote request is made, the response saved to file if successful, and the target response returned as the real container that a data handler would then open.

Constructor & Destructor Documentation

◆ S3Container()

s3::S3Container::S3Container ( const std::string & sym_name,

◆ dump()

void s3::S3Container::dump ( std::ostream & strm) const
overridevirtual

dumps information about this object

Displays the pointer value of this instance along with information about this container.

Parameters

◆ filter_response()

void s3::S3Container::filter_response ( const std::map< std::string, std::string, std::less<> > & content_filters) const

Filter the cached resource. Each key in content_filters is replaced with its associated map value.

WARNING: Does not lock cache. This method assumes that the process has already acquired an exclusive lock on the cache file.

WARNING: This method will overwrite the cached data with the filtered result.

Parameters
content_filtersA map of key value pairs which define the filter operation. Each key found in the resource will be replaced with its associated value.
