public void stamp(InputStream inputStream,
 Object context,
 OutputStream outputStream)
           throws OfficeStamperException

Stamps the template present in the given InputStream with the context given and writes the result to the provided OutputStream. This method first uses the loader to load the template from the InputStream into a type T instance, then uses the stamper to perform the stamp operation using the template and context, writing the result out to the OutputStream.

Parameters:

inputStream - template to stamp

context - context to use for stamping

outputStream - output stream to write the result to

Throws:

OfficeStamperException - if the stamping fails for any reason
