Class CsvMapperFactory

java.lang.Object

org.sfm.csv.CsvMapperFactory

public final class CsvMapperFactory
extends Object

CsvMapperFactory is not Thread-Safe but the mappers are. It is strongly advised to instantiate one mapper per class for the life of your application.

You can instantiate dynamic mapper which will use the first line of the csv file to figure out the list of the columns or a static one using a builder.

// create a dynamic mapper targeting MyClass
CsvMapperFactory
.newInstance()
.newMapper(MyClass.class);

// create a static mapper targeting MyClass
CsvMapperFactory
.newInstance()
.newBuilder(MyClass.class)
.addMapping("id")
.addMapping("field1")
.addMapping("field2")
.mapper();

Parameters:

mapperBuilderErrorHandler - the MapperBuilderErrorHandler

Returns:

the current factory

rowHandlerErrorHandler

public CsvMapperFactory rowHandlerErrorHandler(RowHandlerErrorHandler rowHandlerErrorHandler)

Set a new RowHandlerErrorHandler. Use to handle error thrown by the RowHandler on the forEach call.

Parameters:

rowHandlerErrorHandler - the RowHandlerErrorHandler

Returns:

the current factory

useAsm

public CsvMapperFactory useAsm(boolean useAsm)

Parameters:

useAsm - false if you want to disable asm usage.

Returns:

the factory

failOnAsm

public CsvMapperFactory failOnAsm(boolean failOnAsm)

Parameters:

failOnAsm - true if don't want to recover from an asm generation failure of the mapper

Returns:

the factory

asmMapperNbFieldsLimit

public CsvMapperFactory asmMapperNbFieldsLimit(int asmMapperNbFieldsLimit)

change the number of fields threshold after which an asm mapper is not generated.

the default value is calculated from the benchmark results, currently 240.

Parameters:

asmMapperNbFieldsLimit - the limit after which it does not use asm for the mapper.

Returns:

the factory

maxMethodSize

public CsvMapperFactory maxMethodSize(int maxMethodSize)

Number needs to be a power of 2, do not use if you don't know what it does.

Parameters:

maxMethodSize - the max method size, needs be a power of 2.

Returns:

the factory.

disableAsm

public CsvMapperFactory disableAsm(boolean disableAsm)

Parameters:

disableAsm - true if you want to disable asm.

Returns:

the current factory
