Example 6 with ListDouble

use of org.diirt.util.array.ListDouble in project yamcs-studio by yamcs.

the class ValueFactory method wrapValue.

/**
 * Takes a java objects and wraps it into a vType. All numbers are wrapped
 * as VDouble. String is wrapped as VString. double[] and ListDouble are wrapped as
 * VDoubleArray. A List of String is wrapped to a VStringArray. Alarms
 * are alarm, time are timeNow() and display are displayNone();
 *
 * @param value the value to wrap
 * @param alarm the alarm for the value
 * @return the wrapped value
 * @deprecated use {@link #toVType(java.lang.Object, org.diirt.vtype.Alarm, org.diirt.vtype.Time, org.diirt.vtype.Display) }
