Method Detail

fields

@Support
LoaderJSONOptionsStep<R> fields(Field<?>... fields)

Specify the fields to be loaded into the table in the correct order.

The JSON column at index i is inserted into the table field at index i. If fields[i] == null or fields.length <= i, then the JSON column is skipped.

fields

@Support
LoaderJSONOptionsStep<R> fields(Collection<? extends Field<?>> fields)

Specify the fields to be loaded into the table in the correct order.

The JSON column at index i is inserted into the table field at index i. If new ArrayList(fields).get(i) == null or new ArrayList(fields).size() <= i, then the JSON column is skipped.

fields

@Support
LoaderJSONOptionsStep<R> fields(LoaderFieldMapper mapper)

Specify a function to apply on each input field to receive the target table's field.

The input field obtained from LoaderFieldMapper.LoaderFieldContext.field() wraps the JSON column name if any, or an unspecified field enumeration is used. The LoaderFieldMapper.LoaderFieldContext.index() property corresponds to the JSON column index in enumeration order.

fieldsFromSource

@Support
LoaderJSONOptionsStep<R> fieldsFromSource()

Indicate that all input fields which have a corresponding field in the target table (with the same name) should be loaded.

When executing the loader input fields for which there is no match in the target table will be logged and if no field names can be derived for the input data a LoaderConfigurationException will be reported.
