Methodendetails

fields

@NotNull
@CheckReturnValue
@Support
@NotNull 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

@NotNull
@CheckReturnValue
@Support
@NotNull 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

@NotNull
@CheckReturnValue
@Support
@NotNull 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

@Deprecated(forRemoval=true,
            since="3.14")
@NotNull
@CheckReturnValue
@Support
@NotNull LoaderCSVOptionsStep<R> fieldsFromSource()

Veraltet, zur Entfernung: Dieses API-Element wird in einer zukünftigen Version entfernt.

- 3.14.0 - [#10010] - Use fieldsCorresponding() instead.

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

Löst aus:

LoaderConfigurationException - When the source data does not expose field names.

fieldsCorresponding

@NotNull
@CheckReturnValue
@Support
@NotNull LoaderCSVOptionsStep<R> fieldsCorresponding()

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