AbstractHTTPQuery

protected AbstractHTTPQuery(SPARQLProtocolSession httpClient,
                            QueryLanguage queryLanguage,

Method Detail

getHttpClient

protected SPARQLProtocolSession getHttpClient()

Returns:

Returns the SPARQLProtocolSession to be used for all HTTP based interaction

getBindingsArray

public Binding[] getBindingsArray()

setMaxExecutionTime

public void setMaxExecutionTime(int maxExecutionTime)

Description copied from interface: Operation

Specifies the maximum time that an operation is allowed to run. The operation will be interrupted when it exceeds the time limit. Any consecutive requests to fetch query results will result in QueryInterruptedExceptions or UpdateExecutionExceptions (depending on whether the operation is a query or an update).

Specified by:

setMaxExecutionTime in interface Operation

Overrides:

setMaxExecutionTime in class AbstractOperation

Parameters:

maxExecutionTime - The maximum query time, measured in seconds. A negative or zero value indicates an unlimited execution time (which is the default).

toString

public String toString()

Overrides:

toString in class Object
