public <I,F extends DecodingFormatFactory<I>> DecodingFormat<I> discoverDecodingFormat(Class<F> formatFactoryClass,
                                                                                       org.apache.flink.configuration.ConfigOption<String> formatOption)

Discovers a DecodingFormat of the given type using the given option as factory identifier.

discoverOptionalDecodingFormat

public <I,F extends DecodingFormatFactory<I>> Optional<DecodingFormat<I>> discoverOptionalDecodingFormat(Class<F> formatFactoryClass,
                                                                                                         org.apache.flink.configuration.ConfigOption<String> formatOption)

Discovers a DecodingFormat of the given type using the given option (if present) as factory identifier.

discoverEncodingFormat

public <I,F extends EncodingFormatFactory<I>> EncodingFormat<I> discoverEncodingFormat(Class<F> formatFactoryClass,
                                                                                       org.apache.flink.configuration.ConfigOption<String> formatOption)

Discovers a EncodingFormat of the given type using the given option as factory identifier.

discoverOptionalEncodingFormat

public <I,F extends EncodingFormatFactory<I>> Optional<EncodingFormat<I>> discoverOptionalEncodingFormat(Class<F> formatFactoryClass,
                                                                                                         org.apache.flink.configuration.ConfigOption<String> formatOption)

Discovers a EncodingFormat of the given type using the given option (if present) as factory identifier.

validate

public void validate()

Validates the options of the DynamicTableFactory. It checks for unconsumed option keys.

validateExcept

public void validateExcept(String... prefixesToSkip)

Validates the options of the DynamicTableFactory. It checks for unconsumed option keys while ignoring the options with given prefixes.

The option keys that have given prefix prefixToSkip would just be skipped for validation.

参数:

prefixesToSkip - Set of option key prefixes to skip validation

getOptions

public org.apache.flink.configuration.ReadableConfig getOptions()

Returns all options of the table.
