Method Details

getSetterValue

public CustomSetterValue<?> getSetterValue()

The getter of the setter value.

Returns:

Returns the setter which should be populated with the final value for the column

initialize

public void initialize(CustomSetterValue<?> setterValue,
 Map<String,String> importProperties)

initializes given Setter and Import Properties

Parameters:

setterValue - the setter for this Column

importProperties - The custom properties map passed in import method

getConstantColumnValue

public String getConstantColumnValue()

The getter to retrieve the constantColumnValue

Returns:

the Constant Column Value

setConstantColumnValue

public void setConstantColumnValue(String constantColumnValue)

The Constant Column Value as passed in from ui

Parameters:

constantColumnValue - The value that represents the ConstantColumnValue

processValues

public List<CustomSetterValue<?>> processValues(@NotNull
 @NotNull Map<String,Object[]> columnNameToValueMap,
 int size,
 long destEnd)
                                         throws RowProcessingException

The method is invoked by the CustomSetter Column Parser by incorporating the values from all dependent columns If dependent columns are not provided then the map would contain values from all the columns Note no change for Constant Column values they need to be retrieved using ImportFieldWriter.getConstantColumnValue(String)

Parameters:

columnNameToValueMap - The column name to corresponding CustomValue array map

size - The size of the chunk, which is the same as the size of CustomSetterValue array in the map

destEnd - The exclusive end index of the destination range.

Returns:

The processed custom setter column values for each row

Throws:

RowProcessingException - Thrown if processing errors occur when parsing to create Csv records

getSetterCopy

protected CustomSetterValue<?> getSetterCopy()

Returns a new CustomSetterValue instance that is a copy of the setter present in the FieldWriter instance.

Returns:

new instance of CustomSetterValue that is identical to the existing setter

processField

public void processField(@NotNull
 @NotNull Map<String,Object> columnNameToValueMap)

The method is invoked by the CustomSetter Column Parser by incorporating the values from all dependent columns If dependent columns are not provided then the map would contain values from all the columns Note no change for Constant Column values they need to be retrieved using ImportFieldWriter.getConstantColumnValue(String)

Parameters:

columnNameToValueMap - The column name to corresponding CustomValue array map
