Example 86 with FieldValue

use of com.yahoo.document.datatypes.FieldValue in project vespa by vespa-engine.

the class ValueUpdate method createAddAll.

/**
 * Creates a new value update
 * specifying an addition of all key/weight pairs in a weighted set to a weighted set. If this method
 * is used on an array data type, the weights will be omitted. Note that this method is just a convenience method,
 * it simply iterates through the set and creates value updates by calling createAdd() for each element.
 *
 * @param set a WeightedSet containing the key/weight pairs to add
 * @return a ValueUpdate specifying the addition
 * @throws IllegalArgumentException      if the runtime type of values does not match the type required
 * @throws UnsupportedOperationException if the field type is not weighted set or array
 * @see ValueUpdate#createAdd(FieldValue, Integer)
