Example 36 with IonStruct

use of com.amazon.ion.IonStruct in project ion-hive-serde by amzn.

the class IonStructToMapObjectInspector method getMap.

@Override
public Map<?, ?> getMap(final Object data) {
    if (IonUtil.isIonNull((IonValue) data)) {
        return null;
    }
    final IonStruct struct = (IonStruct) data;
    // sets the initial size of the map to avoid growing as it's immutable while using the default HashMap load
    // factor to maintain the same collision performance
    final int size = (int) Math.ceil(struct.size() / DEFAULT_LOAD_FACTOR);
    final Map<String, IonValue> map = new HashMap<>(size, DEFAULT_LOAD_FACTOR);
    for (IonValue v : struct) {
