public class CsvDataSource
extends java.lang.Object
To access data of the corresponding file or stream while assembling a document, pass an instance of this class as a data source to one of DocumentAssembler
. assembleDocument overloads.
In template documents, a CsvDataSource
instance should be treated in the same way as if it was a DataTable
instance. For more information, see template syntax reference(https://docs.groupdocs.com/display/assemblyjava/Template+Syntax+-+Part+1+of+2#TemplateSyntax-Part1of2-UsingDataSources).
Data types of comma-separated values are determined automatically upon their string representations. So in template documents, you can work with typed values rather than just strings. The engine is capable to automatically recognize values of the following types:
java.lang.Integer
java.lang.Long
java.lang.Double
java.lang.Boolean
java.util.Date
java.lang.String
Note that for automatic recognition of data types to work, string representations of comma-separated values should be formed using invariant culture settings.
To override default behavior of CSV data loading, initialize and pass a CsvDataLoadOptions
instance to a constructor of this class.
