Member Function Documentation

virtual bool check_compatible ( std::istream & is ) const

protectedvirtual

Read the parameters from a stream (as written by write()) and check that they are compatible with these parameters.

Parameters

is	Stream to read from.

Returns: Return true if the read parameters are compatitble with these parameters; false otherwise.

Reimplemented from PercyParams.

virtual std::vector<const PercyParams*> create_worker_params ( std::vector< Dimension > worker_dims ) const

virtual

Create protocol parameters for threads/workers.

worker_dims The database dimensions for each thread/worker.

Returns: The protocol parameters for each thread/worker.

Implements PercyParams.

virtual dbsize_t request_size ( nqueries_t num_queries = 1 ) const

virtual

Get the size of a client to server request.

Parameters

num_queries The number of queries in the request. (Default: 1)

Implements PercyParams.

virtual dbsize_t response_size ( nqueries_t num_queries = 1 ) const

virtual

Get the size of a server to client response.

Parameters

num_queries The number of queries in the request. (Default: 1)

Implements PercyParams.

virtual dbsize_t server_block_size ( ) const

inlinevirtual

Get the size of each block in the database that the datastore will actually use.

This may be different than block_size() when tau-independence is used.

Reimplemented from PercyParams.

virtual void write ( std::ostream & os ) const

protectedvirtual

Write the parameters to a stream to check compatibility.

Parameters

os	Stream to write to.

Reimplemented from PercyParams.
