Example 1 with UnaryExpr
use of org.apache.asterix.lang.common.expression.UnaryExpr in project asterixdb by apache.
the class CloneAndSubstituteVariablesVisitor method visit.
@Override
public Pair<ILangExpression, VariableSubstitutionEnvironment> visit(UnaryExpr u, VariableSubstitutionEnvironment env) throws CompilationException {
Pair<ILangExpression, VariableSubstitutionEnvironment> p1 = u.getExpr().accept(this, env);
UnaryExpr newU = new UnaryExpr(u.getExprType(), (Expression) p1.first);
return new Pair<>(newU, env);
}
