Detailed Description
This is an abstract base class for holding the ASN.1 variable width character string types (GraphicString, GeneralString, TeletexString, T61String, VideotexString, ObjectDescriptor).
Constructor & Destructor Documentation
| internal Asn1VarWidthCharString | ( | short | typeCode | ) | [protected] |
The default constructor creates an empty string object.
- Parameters:
-
typeCode Universal ID code for ASN.1 character string
| internal Asn1VarWidthCharString | ( | System.String | data, | |
| short | typeCode | |||
| ) | [protected] |
This version of the constructor can be used to set the string mValue member variable to the given string.
- Parameters:
-
data Character string typeCode Universal ID code for ASN.1 character string
Member Function Documentation
| virtual void Decode | ( | Asn1PerDecodeBuffer | buffer, | |
| long | lower, | |||
| long | upper | |||
| ) | [virtual] |
This overloaded version of the Decode method decodes an ASN.1 character string value in accordance with the packed encoding rules (PER). This version of the method assumes a size constraint is present. A permitted alphabet may be passed, but it will be ignored.
The decoded result is stored in the public mValue member variable in the Asn1CharString base class.
- Parameters:
-
buffer Decode message buffer object lower Effective size constraint lower bound upper Effective size constraint upper bound
| override void Decode | ( | Asn1PerDecodeBuffer | buffer | ) | [virtual] |
This method decodes an ASN.1 character string value in accordance with the packed encoding rules (PER). This version of the method assumes no permitted alphabet or size constraints. Decoded characters are assigned as-is to the output string. The decoded result is stored in the public mValue member variable in the Asn1CharString base class.
- Parameters:
-
buffer Decode message buffer object
Reimplemented from Asn1Type.
| virtual void Encode | ( | Asn1PerOutputStream | outs, | |
| long | lower, | |||
| long | upper | |||
| ) | [virtual] |
This overloaded version of the encode method encodes an ASN.1 character string value directly into the stream, in accordance with the packed encoding rules (PER). This version of the method assumes a size constraint is present. A permitted alphabet may be passed, but it will be ignored.
The value to encode is stored in the public mValue member variable in the Asn1CharString base class.
Also throws any exception thrown by the Asn1PerOutputStream.
- Parameters:
-
outs PER Encode message stream object lower Effective size constraint lower bound upper Effective size constraint upper bound
- Exceptions:
-
Asn1Exception Thrown, if operation is failed.
| override void Encode | ( | Asn1PerOutputStream | outs | ) | [virtual] |
This method encodes an ASN.1 character string value in accordance with the packed encoding rules (PER) directly into the stream. This version of the method assumes no permitted alphabet or size constraints.
The value to encode is stored in the public mValue member variable in the Asn1CharString base class.
Also throws any exception thrown by the Asn1PerOutputStream.
- Parameters:
-
outs PER Encode message stream object
- Exceptions:
-
Asn1Exception Thrown, if operation is failed.

Member Data Documentation
| const int BITSPERCHAR_A = 8 |
The BITSPERCHAR_A constant specifies the number of bits per character for PER (aligned).
| const int BITSPERCHAR_U = 8 |
The BITSPERCHAR_U constant specifies the number of bits per character for PER (unaligned).
