parse

public static Message parse(AttachmentPart soapAttachment)
                     throws SOAPException

Throws:

SOAPException

computeDecodingCharset

public static Charset computeDecodingCharset(Message message)
                                      throws IOException

Reads the first 10k bytes of (binary) messages to determine the charset when not present in the MessageContext.

Throws:

IOException - when it cannot read the first 10k bytes.

computeDecodingCharset

public static Charset computeDecodingCharset(Message message,
                                             int confidence)
                                      throws IOException

Reads the first 10k bytes of (binary) messages to determine the charset when not present in the MessageContext.

Parameters:

confidence - percentage required to successfully determine the charset.

Throws:

IOException - when it cannot read the first 10k bytes.

getMimeType

public static org.springframework.util.MimeType getMimeType(Message message)

Returns the MimeType if present in the MessageContext.

isMimeType

public static boolean isMimeType(Message message,
                                 org.springframework.util.MimeType compareTo)

computeMimeType

public static org.springframework.util.MimeType computeMimeType(Message message)

Computes the MimeType when not available.

NOTE: This is a resource intensive operation, the first 64k is being read and stored in memory.

computeMimeType

public static org.springframework.util.MimeType computeMimeType(Message message,
                                                                String filename)

Computes the MimeType when not available, attempts to resolve the Charset when of type TEXT.

NOTE: This is a resource intensive operation, the first bytes are being read and stored in memory.

generateMD5Hash

public static String generateMD5Hash(Message message)

Resource intensive operation, preserves the message and calculates an MD5 hash over the entire message.

generateCRC32

public static Long generateCRC32(Message message)

Resource intensive operation, preserves the message and calculates an CRC32 checksum over the entire message.

computeSize

public static long computeSize(Message message)

Resource intensive operation, calculates the binary size of a Message.
