Method Detail

isUseBigDecimal

public boolean isUseBigDecimal()

setUseBigDecimal

public SimpleJsonReader setUseBigDecimal(boolean useBigDecimal)

close

public void close()
           throws DataException

Description copied from class: DataEndpoint

Indicates that this endpoint has finished reading or writing.

Overrides:

close in class DataEndpoint

Throws:

DataException

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

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 SimpleJsonReader setAutoCloseReader(boolean autoCloseReader)
