Method Detail

isSmfMessageAvailableAtCurrentPos

public static boolean isSmfMessageAvailableAtCurrentPos(ByteBuffer buf)
                                                 throws IOException

Throws:

IOException

smfSizeReqAtCurrentPos

public static int smfSizeReqAtCurrentPos(ByteBuffer buf)
                                  throws IOException

Throws:

IOException

validateSmfVersion

public static final void validateSmfVersion(int version)
                                     throws IOException

Validates that argument is 2 or 3, if not, throws IOException with good error message.

Parameters:

version - parameter

Throws:

IOException - on error

validateSmfDeclaredLengthLegal

public static final void validateSmfDeclaredLengthLegal(int smfVersion,
                                                        int declaredLength)
                                                 throws IOException
