Method Detail

main

public static void main(String[] args)
                 throws Exception

Issue a query against a SPARQL endpoint. By default, the client will read from stdin. It will write on stdout.

Parameters:

args - (option)* [serviceURL] (query)

where

serviceURL

The URL of the SPARQL endpoint.

query

The SPARQL query (required unless -f is used)

where option is any of

-u

username

-p

password

-timeout

The http connection timeout in milliseconds (default ) -or- ZERO (0) for an infinite timeout.

-method (GET|POST)

The HTTP method for the requests (default GET).

-useCaches (true|false)

Set to false to explicitly disable the use of HTTP connection caches along the route to the http endpoint (default true).

-showQuery

Show the query string.

-showParseTree

Show the SPARQL parse tree (on the client).

-showResults

Show the query results (on stdout).

-verbose

Be verbose.

-quiet

Be quiet.

-f

A file (or directory) containing the query(s) to be run. Each file may contain a single SPARQL query.

-delim

An optional regular expression which delimits query strings within each file. For example, this can match a newline if there is one query per line in the file. When not specified, it is assumed that there is one query per file.

-query

The query follows immediately on the command line (be sure to quote the query).

-clients

The #of client threads which will issue queries (default ONE (1)).

-repeat #

The #of times to present each query. A seed of ZERO (0) will disable the randomized presentation of the queries. The default seed is based on the System clock.

-seed seed

Randomize the presentation of the queries, optionally using the specified seed for the random number generator -or- ZERO (0L) if the queries will be evaluated in the given order.

-defaultGraph

The URI of the default graph to use for the query.

-analytic=(true|false)

Request the analytic query package for the submitted queries.

-baseURI

The baseURI of the query (used when parsing the query).
