Example 1 with UpdateParser

use of org.apache.jena.sparql.lang.UpdateParser in project jena by apache.

the class UpdateAction method parseExecute.

/**
     * Parse update operations into a GraphStore by parsing from an InputStream.
     * @param usingList    A list of USING or USING NAMED statements that be added to all {@link UpdateWithUsing} queries
     * @param dataset      The dataset to apply the changes to
     * @param input        The source of the update request (must be UTF-8). 
     * @param inputBinding Initial binding to be applied to Update operations that can apply an initial binding
     *                     (i.e. UpdateDeleteWhere, UpdateModify).  May be <code>null</code>
     * @param baseURI      The base URI for resolving relative URIs (may be <code>null</code>)
     * @param syntax       The update language syntax
