Examples with VisibilityEvaluator org.vertexium.security.VisibilityEvaluator used on opensource projects

Example 1 with VisibilityEvaluator

use of org.vertexium.security.VisibilityEvaluator in project vertexium by visallo.

the class VisibilityUtils method canRead.

public static boolean canRead(String visibility, String[] authorizations) {
    VisibilityEvaluator visibilityEvaluator = new VisibilityEvaluator(new Authorizations(authorizations));
    ColumnVisibility columnVisibility = new ColumnVisibility(visibility);
    try {
        return visibilityEvaluator.evaluate(columnVisibility);
    } catch (VisibilityParseException ex) {
        throw new RuntimeException("could not evaluate visibility " + visibility, ex);
    }
}

Example 2 with VisibilityEvaluator

use of org.vertexium.security.VisibilityEvaluator in project vertexium by visallo.

the class InMemoryAuthorizations method canRead.

@Override
public boolean canRead(Visibility visibility) {
    Preconditions.checkNotNull(visibility, "visibility is required");
    // this is just a shortcut so that we don't need to construct evaluators and visibility objects to check for an empty string.
    if (visibility.getVisibilityString().length() == 0) {
        return true;
    }
    VisibilityEvaluator visibilityEvaluator = new VisibilityEvaluator(new Authorizations(this.getAuthorizations()));
    ColumnVisibility columnVisibility = new ColumnVisibility(visibility.getVisibilityString());
    try {
        return visibilityEvaluator.evaluate(columnVisibility);
    } catch (VisibilityParseException e) {
        throw new VertexiumException("could not evaluate visibility " + visibility.getVisibilityString(), e);
    }
