Re: [Servingxml-help] header content

[Daniel P. <dan...@sy...>]

Currently, you only have one option to examine the values of specific =
fields in the header or trailer records as they are read.  That is to =
use a sx:flatFileSignature element, with recordType=3D<record type name =
of a header or trailer record>, field=3D<field name in the header or =
trailer record>, custom=3D"yes", class=3D<implementation of =
com.servingxml.components.recordio.flatfile.SignatureMethod>, and =
validate=3D"yes".

Your implementation would look like

public class MySignatureMethod implements SignatureMethod {
  private Value expectedValue;

  public void data(byte[] bytes, int start, int length)
  throws ServingXmlException {
    //  Do nothing
  }

  public void validate(Value expectedValue) throws ServingXmlException {
    this.expectedValue =3D expectedValue;

    //  This is the value for the header/trailer field.  Your only real =
option at this
    //  point is to throw an exception if you don't like it
  }

  public Value getSignature() {
    return expectedValue;
  }
}

Check the element reference on sx:flatFileSignature, and the javadocs =
for SignatureMethod.

  Hi

  I am using sx:flatfileheader to indicate a header record of a flat =
file. How can I examine the contents of this record in Java code. via =
RecordFilter or some other means.

  Thanks
  Ravi
