Example 2 with MNode

use of gov.sandia.n2a.db.MNode in project n2a by frothga.

the class MPart method clearRedundantOverrides.

/**
 *        Clears all top-level document nodes which exactly match the value they override.

 *        models are kept in a clean state by set().

Example 3 with MNode

use of gov.sandia.n2a.db.MNode in project n2a by frothga.

the class MPart method move.

        c.underrideChildren(null, toDoc);
        c.expand();
    } else // Some existing underrides, so merge in collated tree. This is more expensive because it involves multiple calls to set().

Example 4 with MNode

use of gov.sandia.n2a.db.MNode in project n2a by frothga.
