Method Summary

Modifier and TypeMethod and Description
public void
doPostCleanup(BibEntry
the entry to be cleaned-up
entry)

Overrides default org.jabref.logic.importer.ParserFetcher.doPostCleanup.

Performs a cleanup of the fetched entry.

private String
fixStringEncoding(String value)

Method to change character set, to fix output string encoding If we don't convert to the correct character set, the parser outputs anomalous characters.

private Optional<String>
getKeywords(kong.unirest.core.json.JSONObject primaryClass)

public String
getName()

Implements org.jabref.logic.importer.WebFetcher.getName.

Returns the localized name of this fetcher.

private Optional<String>
getOthers(kong.unirest.core.json.JSONObject item, List<String> keys)

public Parser
getParser()

Implements org.jabref.logic.importer.SearchBasedParserFetcher.getParser, org.jabref.logic.importer.EntryBasedParserFetcher.getParser, org.jabref.logic.importer.IdBasedParserFetcher.getParser.

Returns the parser used to convert the response to a list of BibEntry.

public URL
getURLForEntry(BibEntry
the entry to look information for
entry)

Implements org.jabref.logic.importer.EntryBasedParserFetcher.getURLForEntry.

We use MR Lookup instead of the usual search since this tool is also available without subscription and, moreover, is optimized for finding a publication based on partial information.

public URL
getUrlForIdentifier(String
the ID
identifier)

Implements org.jabref.logic.importer.IdBasedParserFetcher.getUrlForIdentifier.

Constructs a URL based on the query.

public URL
getURLForQuery(org.apache.lucene.queryparser.flexible.core.nodes.QueryNode
the root node of the lucene query
luceneQuery)

Implements org.jabref.logic.importer.SearchBasedParserFetcher.getURLForQuery.

Constructs a URL based on the lucene query.

private BibEntry
jsonItemToBibEntry(kong.unirest.core.json.JSONObject item)

private Optional<String>

Method Detail

doPostCleanupback to summary
public void doPostCleanup(BibEntry entry)

Overrides default org.jabref.logic.importer.ParserFetcher.doPostCleanup.

Doc from org.jabref.logic.importer.ParserFetcher.doPostCleanup.

Performs a cleanup of the fetched entry.

Only systematic errors of the fetcher should be corrected here (i.e. if information is consistently contained in the wrong field or the wrong format) but not cosmetic issues which may depend on the user's taste (for example, LateX code vs HTML in the abstract).

Try to reuse existing Formatter for the cleanup. For example, new FieldFormatterCleanup(StandardField.TITLE, new RemoveBracesFormatter()).cleanup(entry);

By default, no cleanup is done.

Parameters
entry:BibEntry

the entry to be cleaned-up

fixStringEncodingback to summary
private String fixStringEncoding(String value)

Method to change character set, to fix output string encoding If we don't convert to the correct character set, the parser outputs anomalous characters. This is observed in case of non-UTF-8 characters, such as accented characters.
