Method Details

writeStreamToFile

public static void writeStreamToFile(InputStream data,
 File destFile,
 Long expectedFileSize)

Writes stream to destination file. If the number of bytes in the stream do not match up with the expected size of the attachment an error will be thrown the write will be aborted.

Parameters:

data - attachment body represented as a stream

destFile - file to copy stream into

expectedFileSize - expected size of the created file. If it is null or zero, the check against the number of bytes in the stream is skipped. The size is only verified against the stream's byte count when it has a non-zero value.

Throws:

AttachmentDataStreamSizeMismatchException - if the number of bytes in the stream does not match the expectedAttachmentSize
