implements DBStrictEqFunctionSymbol

TODO: should it make it a non-DB boolean function symbol? --> that is, downgrading to a non-strict equality?

Description copied from interface: DBFunctionSymbolSerializer

Returns a String in the native query language.

Specified by:

getNativeDBString in interface DBFunctionSymbolSerializer

negate

public ImmutableExpression negate(it.unibz.inf.ontop.com.google.common.collect.ImmutableList<? extends ImmutableTerm> subTerms,
