Class TypeBasedCellValueCoercer<VAL>

java.lang.Object

org.squashtest.tm.service.internal.batchimport.excel.TypeBasedCellValueCoercer<VAL>

All Implemented Interfaces:

CellValueCoercer<VAL>

Direct Known Subclasses:

ImportModeCellCoercer, LiberalBooleanCellCoercer, OptionalDateCellCoercer, OptionalEnumCellCoercer, OptionalIntegerCellCoercer, ParamAssignationModeCellCoercer, StringCellCoercer

public abstract class TypeBasedCellValueCoercer<VAL>
extends Object
implements CellValueCoercer<VAL>

Implementation of CellValueCoercer which tests the cell's type then invokes a specific method. Default implementation of each method throw a CannotCoerceException and are meant to be overriden in subclasses.
