All Implemented Interfaces:

Serializable

public class DataProcessingException
extends TextParsingException

A DataProcessingException is an error thrown during the processing of a record successfully parsed. This type of error usually indicates that the input text has been parsed correctly, but the subsequent transformations applied over the input (generally via a RowProcessor} failed.

Method Detail

getErrorDescription

protected String getErrorDescription()

Returns a generic description of the error. The result of this method is used by getMessage() to print out a general description of the error before a detailed message of the root cause.

Overrides:

getErrorDescription in class TextParsingException

Returns:

a generic description of the error.

getDetails

protected String getDetails()

Subclasses must implement this method to return as much information as possible about the internal state of the parser/writer. Use printIfNotEmpty(String, String, Object) to create a comma-separated list of relevant properties and their (non null) values. The result of this method is used by the getMessage() method to print out these details after the error message.

Overrides:

getDetails in class TextParsingException

Returns:

a String describing the internal state of the parser/writer.

getColumnName

public String getColumnName()

Returns the name of the column from where the error occurred, if available.

Returns:

the name of the column from where the error occurred.

getColumnIndex

public final int getColumnIndex()

Returns the index of the column from where the error occurred, if available.

Overrides:

getColumnIndex in class TextParsingException

Returns:

the index of the column from where the error occurred.

getRow

public final Object[] getRow()

Returns the record being processed when the error occurred, if available.

Returns:

the record being processed when error occurred, if available.

setValue

public final void setValue(Object value)

Defines the value being processed when the error occurred.

Parameters:

value - the value being processed when error occurred.

setValue

public final void setValue(String label,
                           Object value)

Associates a label in the exception message (idenfied in curly braces) with a value being processed when the error occurred. Used for formatting the exception message

Parameters:

label - a label in the exception message - any string enclosed by curly braces.

value - the value being processed when error occurred, that should be replaced by the label in the exception message.

getValue

public final Object getValue()

Returns the value being processed when the error occurred, if available.

Returns:

the value being processed when the error occurred, if available.

setColumnIndex

public final void setColumnIndex(int columnIndex)

Defines the column index being processed when the error occurred.

Defines the name of the column being processed when the error occurred.

Parameters:

columnName - the name of the column being processed when error occurred.

setRow

public final void setRow(Object[] row)

Parameters:

row - the record data processed when the error occurred.

markAsNonFatal

public final void markAsNonFatal()

Marks the error as non fatal and the parsing process might proceed.

public final void markAsHandled(ProcessorErrorHandler handler)

Marks the error as handled so it doesn't trigger a ProcessorErrorHandler again.

Parameters:
