Class PrimitiveFieldType

  • Direct Known Subclasses:
    AbstractEnumField, BoolField, NumericFieldType, StrField
    public abstract class PrimitiveFieldType
extends FieldType
    Abstract class defining shared behavior for primitive types Intended to be used as base class for non-analyzed fields like int, float, string, date etc, and set proper defaults for them

    • Method Detail

      • init

        protected void init​(IndexSchema schema,
                    Map<String,​String> args)
        Description copied from class: FieldType
        subclasses should initialize themselves with the args provided and remove valid arguments. leftover arguments will cause an exception. Common boolean properties have already been handled.
        Overrides:
        init in class FieldType

      • enableDocValuesByDefault

        protected boolean enableDocValuesByDefault()
        Description copied from class: FieldType
        Returns whether this field type should enable docValues by default for schemaVersion >= 1.7. This should not be enabled for fields that did not have docValues implemented by Solr 9.7, as users may have indexed documents without docValues (since they weren't supported). Flipping the default docValues values when they upgrade to a new version will break their index compatibility.

        New field types can enable this without issue, as long as they support docValues.

        Overrides:
        enableDocValuesByDefault in class FieldType

      • getDefaultMultiValueSelectorForSort

        public FieldType.MultiValueSelector getDefaultMultiValueSelectorForSort​(SchemaField field,
                                                                        boolean reverse)
        Description copied from class: FieldType
        Method for indicating which FieldType.MultiValueSelector (if any) should be used when sorting on a multivalued field of this type for the specified direction (asc/desc). The default implementation returns null (for all inputs).
        Overrides:
        getDefaultMultiValueSelectorForSort in class FieldType
        Parameters:
        field - The SchemaField (of this type) in question
        reverse - false if this is an ascending sort, true if this is a descending sort.
        Returns:
        the implicit selector to use for this direction, or null if implicit sorting on the specified direction is not supported and should return an error.
