R6 Class for OSV Query Endpoint

Source: R/RosvQuery1.R
RosvQuery1.Rd

An R6 class to provide a lower-level interface to the query endpoint of the OSV API.

Value

An R6 object to operate with OSV query endpoint.

Details

Pageination is implemented via httr2::req_perform_iterative() and a private method for extracting tokens automatically. When initialized, the page_token is set to NULL; if a token is generated for large results the process is handled internally. The response object will contain a list of all returned responses before any formatting occurred. The content field will contain the list of vulnerabilities which may be further parsed into a table format.
