Interface ErrorFactory

All Known Implementing Classes:

JsonLoaderImpl, KafkaJsonLoader

public interface ErrorFactory

To avoid coupling the JSON structure parser with Drill's error reporting mechanism, the caller passes in an instance of this error factory which will build the required errors, including filling in caller-specific context.

Method Summary

Modifier and Type	Method and Description
RuntimeException	ioException(IOException e) I/O error reported from the Jackson JSON parser.
RuntimeException	messageParseError(MessageParser.MessageContextException e) Parser is configured to find a message tag within the JSON and a syntax occurred when following the data path.
RuntimeException	parseError(String string, com.fasterxml.jackson.core.JsonParseException e) The Jackson JSON parser failed to start on the input file.
RuntimeException	structureError(String string) General structure-level error: something very unusual occurred in the JSON that passed Jackson, but failed in the structure parser.
RuntimeException	syntaxError(com.fasterxml.jackson.core.JsonParseException e) The Jackson parser reported a syntax error.
RuntimeException	syntaxError(com.fasterxml.jackson.core.JsonToken token) Received an unexpected token.
RuntimeException	typeError(UnsupportedConversionError e) The Jackson parser reported an error when trying to convert a value to a specific type.
RuntimeException	unrecoverableError() Error recovery is on, the structure parser tried to recover, but encountered too many other errors and gave up.

Method Detail

parseError

RuntimeException parseError(String string,
                            com.fasterxml.jackson.core.JsonParseException e)

The Jackson JSON parser failed to start on the input file.

ioException

RuntimeException ioException(IOException e)

I/O error reported from the Jackson JSON parser.

structureError

RuntimeException structureError(String string)

General structure-level error: something very unusual occurred in the JSON that passed Jackson, but failed in the structure parser. =

syntaxError

RuntimeException syntaxError(com.fasterxml.jackson.core.JsonParseException e)

The Jackson parser reported a syntax error. Will not occur if recovery is enabled.

typeError

RuntimeException typeError(UnsupportedConversionError e)

The Jackson parser reported an error when trying to convert a value to a specific type. Should never occur since we only convert to the type that Jackson itself identified.

syntaxError

RuntimeException syntaxError(com.fasterxml.jackson.core.JsonToken token)

Received an unexpected token. Should never occur as the Jackson parser itself catches errors.

unrecoverableError

RuntimeException unrecoverableError()

Error recovery is on, the structure parser tried to recover, but encountered too many other errors and gave up.

messageParseError

RuntimeException messageParseError(MessageParser.MessageContextException e)

Parser is configured to find a message tag within the JSON and a syntax occurred when following the data path.
