Thrown when the underlying input stream is malformed based on the configured stream format, and therefore a record could not be accurately read from the stream.In many cases, further reads from the input stream will be unsuccessful.Bean IO supports several common field validation rules when reading an input stream.All field validation rules are validated against the field text before type conversion.For example, if the name of the root element in the previous example's employee file is changed from "employee File" to "employees", and "title" was renamed "position", the mapping file could be updated as shown below.attribute on any mapping component (stream, group, record, segment or field).Before diving into the details, let's start with a basic example using the employee input file from Section 2.1 after it's been converted to XML (shown below).
Bean IO is an open source Java framework for reading and writing Java beans or plain old java objects (POJO's) from a flat file or stream.
For example, let's suppose our employee file contains namespaces as shown below.
is set to '*', any namespace is allowed when unmarshalling XML, and no namespace declaration will be made when marshalling XML.
When field trimming is enabled, , all validations are performed after the field's text has first been trimmed.
Field validations are ignored when writing to an output stream.
