Constructor Detail

JsonRecordReader

public JsonRecordReader(JsonParser reader)

Method Detail

createFactory

protected JsonFactory createFactory()

isDebug

public boolean isDebug()

setDebug

public JsonRecordReader setDebug(boolean debug)

isUseBigDecimal

public boolean isUseBigDecimal()

setUseBigDecimal

public JsonRecordReader setUseBigDecimal(boolean useBigDecimal)

addRecordBreak

public JsonRecordReader addRecordBreak(String locationPathAsString)

isRecordBreak

protected boolean isRecordBreak(JsonXmlNode node)

close

public void close()

Description copied from class: DataEndpoint

Indicates that this endpoint has finished reading or writing.

Overrides:

close in class DataEndpoint

readImpl

protected Record readImpl()
                   throws Throwable

Description copied from class: DataReader

Overridden by subclasses to read the next record from this DataReader. The default implementation of DataReader.read() now insures that this method will not be called again after it returns a null.

If no record is available, null will be returned.

Specified by:

readImpl in class DataReader

Throws:

Throwable

nextNode

protected boolean nextNode()
                    throws DataException

Throws:

DataException

newNode

protected JsonXmlNode newNode(JsonXmlNode parentNode,
                              JsonToken token,
                              String name,
                              JsonLocation tokenLocation)

newField

protected JsonXmlNode newField(JsonXmlNode parentNode,
                               JsonToken token,
                               String name,
                               JsonLocation tokenLocation)

newValue

protected JsonXmlNode newValue(JsonXmlNode parentNode,
                               JsonToken token,
                               Object value)

isLineageSupported

public boolean isLineageSupported()

Overrides:

isLineageSupported in class DataReader

addLineage

protected Record addLineage(Record record)

Overrides:

addLineage in class DataReader

addExceptionProperties

public DataException addExceptionProperties(DataException exception)

Description copied from class: Endpoint

Adds this endpoint's current state to a DataException. Since this method is called whenever an exception is thrown, subclasses should override it to add their specific information.

Overrides:

addExceptionProperties in class DataReader

isAutoCloseReader

public boolean isAutoCloseReader()

setAutoCloseReader

public JsonRecordReader setAutoCloseReader(boolean autoCloseReader)
