IMPORTING¶

Required arguments:¶

`iv_domainidentifier` `TYPE /AWS1/DZNDOMAINID` `/AWS1/DZNDOMAINID`¶

The identifier of the Amazon DataZone domain.

`it_match` `TYPE /AWS1/CL_DZNMATCHCLAUSE=>TT_MATCHCLAUSES` `TT_MATCHCLAUSES`¶

List of query match clauses.

Optional arguments:¶

`iv_maxresults` `TYPE /AWS1/DZNMAXRESULTS` `/AWS1/DZNMAXRESULTS`¶

The maximum number of entities to return in a single call to QueryGraph. When the number of entities to be listed is greater than the value of MaxResults, the response contains a NextToken value that you can use in a subsequent call to QueryGraph to list the next set of entities.

`iv_nexttoken` `TYPE /AWS1/DZNPAGINATIONTOKEN` `/AWS1/DZNPAGINATIONTOKEN`¶

When the number of entities is greater than the default value for the MaxResults parameter, or if you explicitly specify a value for MaxResults that is less than the number of entities, the response includes a pagination token named NextToken. You can specify this NextToken value in a subsequent call to QueryGraph to list the next set of entities.

`io_additionalattributes` `TYPE REF TO /AWS1/CL_DZNADDLATTRIBUTES` `/AWS1/CL_DZNADDLATTRIBUTES`¶

Additional details on the queried entity that can be requested in the response.

RETURNING¶

`oo_output` `TYPE REF TO /aws1/cl_dznquerygraphoutput` `/AWS1/CL_DZNQUERYGRAPHOUTPUT`¶

Examples¶

Syntax Example¶

This is an example of the syntax for calling the method. It includes every possible argument and initializes every possible value. The data provided is not necessarily semantically accurate (for example the value "string" may be provided for something that is intended to be an instance ID, or in some cases two arguments may be mutually exclusive). The syntax shows the ABAP syntax for creating the various data structures.
