Detailed Description

ASN.1 Time control base class. The ASN1CTime class is derived from the ASN1CType base class. It is used as the abstract base class for generated control classes for the ASN.1 Generalized Time ([UNIVERSAL 24] IMPLICIT VisibleString) types and Universal Time ([UNIVERSAL 23] IMPLICIT VisibleString) types. This class provides utility methods for operating on the time information referenced by the generated class. This class can also be used inline to operate on the times within generated time string elements in a SEQUENCE, SET, or CHOICE construct. The time string are generally formatted according to ISO 8601 format with some exceptions (X.680).


Constructor & Destructor Documentation

EXTRTMETHOD ASN1CTime::ASN1CTime ( OSRTMessageBufferIF &  msgBuf,
char *&  buf,
int  bufSize,
OSBOOL  useDerRules 
)

This constructor creates a time string from buffer.

It does not deep-copy the data; it just assigns the passed array to an internal reference variable. The object will then directly operate on the given data variable.

Parameters:
msgBuf Reference to an OSRTMessage buffer derived object (for example, ASNBEREncodeBuffer).
buf Reference to a pointer to a time string buffer.
bufSize Size of buffer in bytes.
useDerRules Use the Distinguished Encoding Rules (DER) to operate on this time value.

ASN1VisibleString &  buf,
OSBOOL  useDerRules 
)

This constructor creates a time string from an ASN1VisibleString object.

It does not deep-copy the data; it just assigns the passed object to an internal reference variable. The object will then directly operate on the given data variable.

Parameters:
msgBuf Reference to an OSRTMessage buffer derived object (for example, ASNBEREncodeBuffer).
buf Reference to a visible string object to hold the time data.
useDerRules Use the Distinguished Encoding Rules (DER) to operate on this time value.
