Detailed Description

This class is a standard named event handler for printing the data in an encoded message in a human-readable format. Note that this handler will work with data encoded using any of the encoding rules (BER, DER, or PER).

Constructor & Destructor Documentation

This constructor sets the output stream to standard output.

Asn1TraceHandler ( System.IO.StreamWriter  ps  ) 

This constructor sets the output stream to the given StreamWriter.

Parameters:
ps StreamWriter object

Member Function Documentation

virtual void Characters ( System.String  svalue,
short  typeCode 
) [virtual]

The characters callback method is invoked when content (primitive data) is encountered. A stringified representation of the parsed value is returned.

Parameters:
svalue Stringified representation of the parsed value. The representation will be in ASN.1 value format.
typeCode Identifier specifying the type of the parsed data variable. The enumerated list of values that might appear here is provided in the the Asn1Type class (see the documentation on this class for a full list of the names).

Implements Asn1NamedEventHandler.

virtual void EndElement ( System.String  name,
int  index 
) [virtual]

The endElement callback method is invoked when the end of an element within a constructed type (SEQUENCE, SET, SEQUENCE OF, SET OF, or CHOICE) is detected.

Parameters:
name Name of the parsed element.
index Index of element in array. Only used for SEQUENCE OF or SET OF elements. Set to -1 for all others.

Implements Asn1NamedEventHandler.

virtual void StartElement ( System.String  name,
int  index 
) [virtual]

The StartElement callback method is invoked when the start of an element within a constructed type (SEQUENCE, SET, SEQUENCE OF, SET OF, or CHOICE) is encountered.

Parameters:
name Name of the parsed element.
index Index of element in array. Only used for SEQUENCE OF or SET OF elements. Set to -1 for all others.

Implements Asn1NamedEventHandler.
