Method Detail

init

public void init(Properties batchConfig)

Specified by:

init in interface BatchService

toInternalRepresentation

public <T> byte[] toInternalRepresentation(T dataObject)

Description copied from interface: DataRepresentationService

Convert the given dataObject into something which can be stored in a BLOB in the database.

Specified by:

toInternalRepresentation in interface DataRepresentationService

Parameters:

dataObject - the object to store or null if no data is to be stored

Returns:

the internal representation of the dataObject

toJavaRepresentation

public <T> T toJavaRepresentation(byte[] internalRepresentation)

Description copied from interface: DataRepresentationService

Convert the internal representation stored in the PersistenceManagerService to the Java objects needed by the batch artifacts.

Specified by:

toJavaRepresentation in interface DataRepresentationService

Parameters:

internalRepresentation - the String representation which we store in the databas

Returns:

the dataObject

convertCustomTypes

protected <T> byte[] convertCustomTypes(T dataObject)

This is an extension point for other serialisation algorithms.

convertJavaNativeTypes

protected <T> byte[] convertJavaNativeTypes(T dataObject)

This method converts java native types to a 'nice' string representation which will be stored in the database.

Returns:

the String representation or null if the dataObject was not a native Java type

convertBackJavaNativeTypes

protected <T> T convertBackJavaNativeTypes(String typeVal,
                                           String value)

convertJava7DateTypes

protected <T> byte[] convertJava7DateTypes(T dataObject)

Convert javas internal Date objects to db representation. The converted types are:

• java.util.Date
• java.sql.Date
• java.sql.Timestamp

convertBackJava7DateTypes

protected <T> T convertBackJava7DateTypes(String typeVal,
                                          String valueVal)

invokeStaticMethod

protected Object invokeStaticMethod(String typeVal,
                                    String methodName,
                                    Class paramType,
                                    String valueVal)

convertSerializableObjectTypes

protected <T> byte[] convertSerializableObjectTypes(T dataObject)

This is the default operation if no other way to serialise the data was used

convertBackSerializableObjectTypes

protected <T> T convertBackSerializableObjectTypes(byte[] internalRepresentation)

toBatchEeData

protected byte[] toBatchEeData(Class<?> type,
                               String stringRepresentation)

getClassLoader

protected ClassLoader getClassLoader()

getSimpleDateFormat

protected SimpleDateFormat getSimpleDateFormat()

getTimestampDateFormat

protected SimpleDateFormat getTimestampDateFormat()

Attention: The nanos must get concatenated separately as there is no formatter for nanos!
