Detailed Description

This class represents the ASN.1 ENUMERATED built-in type. It is declared to be an abstract class and therefore cannot be used on its own. It must be extended by a specific enumerated type class.

Constructor & Destructor Documentation

◆ Asn1Enumerated() [1/2]

The default constructor sets the enumerated value to undefined.

◆ Asn1Enumerated() [2/2]

Asn1Enumerated ( int  value_)

This constructor creates an enumerated object from a integer value.

Parameters
value_Integer value

Member Function Documentation

◆ Encode() [1/8]

override int Encode ( Asn1BerEncodeBuffer  buffer,
bool  explicitTagging 
)
virtual

This method encodes an ASN.1 enumerated value including the UNIVERSAL tag value and length if explicit tagging is specified. This overloaded version uses the Basic Encoding Rules (BER).

Parameters
bufferEncode message buffer object
explicitTaggingFlag indicating explicit tagging should be done
Returns
Length of component or negative status value

Reimplemented from Asn1Type.

References Asn1BerEncodeBuffer.EncodeIntValue(), and Asn1BerEncodeBuffer.EncodeTagAndLength().

◆ Encode() [2/8]

virtual void Encode ( Asn1PerEncodeBuffer  buffer,
long  lower,
long  upper 
)
virtual

This method encodes an ASN.1 enumerated value using the Packed Encoding Rules (PER).

Parameters
bufferPER Encode message buffer object
lowerSmallest enumerated value in the set
upperLargest enumerated value in the set

References Asn1PerEncodeBuffer.EncodeConsWholeNumber(), Asn1XerEncoder.EncodeNamedValue(), and Diag.Prtln().

◆ Encode() [3/8]

override void Encode ( Asn1XerEncoder  buffer,
System.String  elemName 
)
virtual

This method encodes an ASN.1 enumerated value using the XML encoding rules (XER).

Parameters
bufferEncode message buffer object
elemNameElement name

Reimplemented from Asn1Type.

◆ Encode() [4/8]

virtual void Encode ( Asn1XerEncodeBuffer  buffer)
virtual

This method encodes an ASN.1 enumerated value using the XML encoding rules (XER). This method does not add start and end tags (<tag> and </tag>), only value is encoded (<val1/> or <val2/>).

Parameters
bufferEncode message buffer object

References Asn1XmlEncoder.EncodeNamedValue(), and Asn1XerEncodeBuffer.EncodeNamedValueElement().

◆ Encode() [5/8]

override void Encode ( Asn1XmlEncoder  buffer,
System.String  elemName,
System.String  nsPrefix 
)
virtual

This method encodes an ASN.1 enumerated value using the Obj-Sys XML Encoding rules. It encodes the value as XML text.

Parameters
bufferEncode message buffer object
elemNameElement name
nsPrefixElement namespace value

Reimplemented from Asn1Type.

◆ Encode() [6/8]

virtual void Encode ( Asn1XmlEncoder  buffer,
String  elemName,
String  nsPrefix,
bool  asText 
)
virtual

This method encodes an ASN.1 enumerated value. It is for use with extended-XER.

Parameters
bufferEncode message buffer object
elemNameElement name
nsPrefixXML element name space prefix
asTextIf true, encode the value as XML text, otherwise encode as an empty element.

References Asn1XmlXerEncoder.Copy(), Asn1XmlEncoder.EncodeEmptyElement(), Asn1XmlEncoder.EncodeEndElement(), and Asn1XmlEncoder.EncodeStartElement().

◆ Encode() [7/8]

override void Encode ( Asn1BerOutputStream  outs,
bool  explicitTagging 
)
virtual

This method encodes and writes to the stream an ASN.1 enumerated value including the UNIVERSAL tag value and length if explicit tagging is specified. This overloaded version uses the Basic Encoding Rules (BER).

Throws, Exception thrown by C# System.IO.Stream for I/O error

Parameters
outsBER Output Stream object
explicitTaggingFlag indicating explicit tagging should be done
Exceptions
Asn1ExceptionThrown, if operation is failed.

Reimplemented from Asn1Type.

◆ Encode() [8/8]

virtual void Encode ( Asn1PerOutputStream  outs,
long  lower,
long  upper 
)
virtual

This method encodes an ASN.1 enumerated value using the Packed Encoding Rules (PER).

Also throws any exception thrown by the underlying Asn1PerOutputStream.

Parameters
outsPER Output Stream object
lowerSmallest enumerated value in the set
upperLargest enumerated value in the set
Exceptions
Asn1ExceptionThrown, if operation is failed.

◆ Equals() [1/2]

virtual bool Equals ( int  value)
virtual

This method compares this enumerated value to the given value for equality.

Parameters
valueThe int or enumerated value to compare with the current Object.
Returns
true if the specified int value is equal to the current Object; otherwise, false.

◆ Equals() [2/2]

override bool Equals ( System.Object  value)

This method compares this enumerated value to the given value for equality.

Parameters
valueThe Object to compare with the current Object. Object should be instance of Asn1Enumerated.
Returns
true if the specified Object is equal to the current Object; otherwise, false.

References Asn1Enumerated.mValue.

◆ GetHashCode()

override int GetHashCode ( )

Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table.

Returns
A hash code for the current Object.

◆ ParseValue()

static int ParseValue ( System.String  value)
static

This method will parse the given enumeration text and set the enumerated value. This method is implemented by the extending class for XER or XML code generation ONLY.

Parameters
valueenumeration text
Returns
Stringified representation of the value

AB: don't make it abstract (it is only for XER)

◆ ToString()

override System.String ToString ( )

This method will return the enumeration text for a given enumerated value.

Returns
Stringified representation of the value

Member Data Documentation

◆ _TAG

new readonly Asn1Tag _TAG
static

The _TAG constant describes the universal tag for this data type (UNIVERSAL 10).

◆ mValue

int mValue

This public member variable is where the enumerated value is stored. This is the value that is encoded when one of the encode methods is called. It is also where the decoded result is stored when a Decode method is called.

Referenced by Asn1Enumerated.Equals().

◆ UNDEFINED

const int UNDEFINED = - 999

The UNDEFINED constant is stored in the mValue member variable when the value of this enumerated type is undetermined.

Property Documentation

◆ Value

int Value
get

The integer value associated with this enumerated value.
