Examples with Selection graphql.language.Selection used on opensource projects

Example 1 with Selection

use of graphql.language.Selection in project structr by structr.

the class GraphQLQuery method init.

// ----- private methods -----
private void init(final SecurityContext securityContext, final Class type, final Field field, final String path) throws FrameworkException {
    final QueryConfig config = getConfig(path);
    config.handleTypeArguments(securityContext, type, field.getArguments());
    final SelectionSet selectionSet = field.getSelectionSet();
    if (selectionSet != null) {
        for (final Selection selection : selectionSet.getSelections()) {
            if (selection instanceof Field) {
                final Field childField = (Field) selection;
                final SelectionSet childSet = childField.getSelectionSet();
                final PropertyKey key = StructrApp.getConfiguration().getPropertyKeyForJSONName(type, childField.getName());
                final Class relatedType = key.relatedType() != null ? key.relatedType() : type;
                // add field to property set
                config.addPropertyKey(key);
                config.handleFieldArguments(securityContext, relatedType, field, childField);
                // recurse
                if (childSet != null) {
                    init(securityContext, relatedType, childField, path + "/" + childField.getName());
                }

Example 2 with Selection

use of graphql.language.Selection in project nextprot-api by calipho-sib.

the class EntryDataFetcherImpl method get.

    }
    Entry entry = entryBuilderService.build(EntryConfig.newConfig(accession).with(category).withPublications().withOverview().withTargetIsoforms());
    if (publicationLimit != -1) {
        List<Publication> publications = entry.getPublications();

    }
    return entry;
