Detailed Description
This is the base class for representing character sets that are defined in ASN.1 permitted alphabet constraints.
Member Function Documentation
◆ GetCharAtIndex()
|
pure virtual |
This method will fetch the character from the permitted alphabet at the given index.
- Parameters
-
index Index of character within the character set
- Returns
- Character at given index
- Exceptions
-
Asn1ConsVioException Index not within define range
Implemented in Asn1CharRange, and Asn1DiscreteCharSet.
Referenced by Asn1UniversalString.Decode(), and Asn1PerDecodeBuffer.DecodeCharString().
◆ GetCharIndex()
|
pure virtual |
This method will determine the index of the given character within the permitted alphabet character set.
- Parameters
-
charValue Character value to search for
- Returns
- Index of character
- Exceptions
-
Asn1ConsVioException Character not found in set
Implemented in Asn1CharRange, and Asn1DiscreteCharSet.
Referenced by Asn1UniversalString.Encode(), and Asn1PerEncodeBuffer.EncodeCharString().
◆ GetNumBitsPerChar()
|
virtual |
This method will return the number of bits-per-character.
- Parameters
-
aligned Boolean value indicating whether number of aligned (true) or unaligned (false) characters should be returned.
- Returns
- Number of bits-per-character
Referenced by Asn1UniversalString.Decode(), Asn1PerDecodeBuffer.DecodeCharString(), Asn1UniversalString.Encode(), Asn1PerEncodeBuffer.EncodeCharString(), and Asn1CharString.validate().
◆ validate()
|
pure virtual |
This method will validate a character string by comparing its contents to the character set. If a character string contains characters that are not in the character set, this method will return false. Otherwise it returns true.
- Parameters
-
s The string to be validated.
- Returns
- False if the string contains invalid characters; true otherwise.
Implemented in Asn1CharRange, and Asn1DiscreteCharSet.
Referenced by Asn1CharString.validate(), and Asn1UniversalString.validate().
Property Documentation
◆ MaxValue
|
get |
Gets the maximum value of the character within the given permitted alphabet character set.
Value: Upper Bound Character or Character with max int value
