unionOf

public SchemaBuilder.UnionFieldTypeBuilder<R> unionOf()

nullable

public SchemaBuilder.BaseFieldTypeBuilder<R> nullable()

A shortcut for building a union of a type and null, with an optional default value of the non-null type.

For example, the two code snippets below are equivalent:

nullable().booleanType().booleanDefault(true)

unionOf().booleanType().and().nullType().endUnion().booleanDefault(true)

optional

public SchemaBuilder.BaseTypeBuilder<SchemaBuilder.FieldAssembler<R>> optional()

A shortcut for building a union of null and a type, with a null default.

For example, the two code snippets below are equivalent:

optional().booleanType()

unionOf().nullType().and().booleanType().endUnion().nullDefault()
