Constructor & Destructor Documentation

Asn1Real (  ) 

The default constructor sets the double value to zero.

Asn1Real ( double  value  ) 

This constructor creates an REAL object from a double value.

Parameters:
value double value

Member Function Documentation

virtual void Decode ( Asn1JsonDecodeBuffer  buffer  )  [virtual]

Decode ASN.1 REAL from JSON.

override void Decode ( Asn1OerDecodeBuffer  buffer  )  [virtual]

Decode a REAL value, encoded according to OER, into this object.

This method applies to unconstrained REAL values and REAL values that are constrained but not meeting the requirements for encoding using IEEE 754 single or double precision format.

Parameters:
buffer 
Exceptions:
IOException 

Reimplemented from Asn1Type.

override void Decode ( Asn1PerDecodeBuffer  buffer  )  [virtual]

This method decodes ASN.1 REAL value using the Packed Encoding Rules (PER). The length and contents components of the message are decoded. The decoded result is stored in the public member 'mValue' in this object.

Parameters:
buffer PER Decode message buffer object

Reimplemented from Asn1Type.

override void Decode ( Asn1BerDecodeBuffer  buffer,
bool  explicitTagging,
int  implicitLength 
) [virtual]

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

Parameters:
buffer Decode message buffer object
explicitTagging Flag indicating element is explicitly tagged
implicitLength Length of contents if implicit

Reimplemented from Asn1Type.

void Decode ( Asn1DecodeBuffer  buffer,
int  length 
) [protected]

This method decodes the content octets of an ASN.1 REAL value into this object, where the REAL was encoded as for BER and the length is taken to be as given.

Note that this method is used for OER also, since OER uses the same content octets as BER, at least in certain cases.

Parameters:
buffer Decode message buffer object
length Length of contents
void DecodeDouble ( Asn1OerDecodeBuffer  buffer  ) 

Decode a REAL value, encoded according to OER in double precision format.

Parameters:
buffer 
Exceptions:
IOException 
void DecodeSingle ( Asn1OerDecodeBuffer  buffer  ) 

Decode a REAL value, encoded according to OER in single precision format.

Parameters:
buffer 
Exceptions:
IOException 
virtual void DecodeXER ( System.String  buffer,
System.String  attrs,
bool  decodingElemName,
bool  modifiedEncodings 
) [virtual]

This method decodes an ASN.1 real value using XER.

Parameters:
buffer String containing data to be decoded
attrs Attributes string from element tag
decodingElemName Pass true if you the ASN.1 value being decoded was encoded as an empty element and buffer is the element name. Such an encoding occurs for the special real values under basic-XER, canonical-XER, and extended-XER without GLOBAL-DEFAULTS MODIFIED-ENCODINGS present.
modifiedEncodings Pass TRUE if decoding under extended-XER with GLOBAL-DEFAULTS MODIFIED-ENCODINGS present.
override void DecodeXML ( System.String  buffer,
System.String  attrs 
)

This method decodes an ASN.1 real value using the XML schema encoding rules(asn2xsd).

Parameters:
buffer String containing data to be decoded
attrs Attributes string from element tag
override void Encode ( Asn1PerOutputStream  outs  )  [virtual]

This method encodes ASN.1 REAL value using the Packed Encoding Rules (PER). The length and contents components of the message are encoded.

Also throws any exception thrown by the Asn1PerOutputStream.

Parameters:
outs PER Output Stream object
Exceptions:
Asn1Exception Thrown, if operation is failed.

Reimplemented from Asn1Type.

override void Encode ( Asn1BerOutputStream  outs,
bool  explicitTagging 
) [virtual]

This method encodes and writes to the stream an ASN.1 real 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:
outs BER Output Stream object
explicitTagging Flag indicating explicit tagging should be done
Exceptions:
Asn1Exception Thrown, if operation is failed.

Reimplemented from Asn1Type.

virtual void Encode ( Asn1JsonOutputStream  outstream  )  [virtual]

Encode this ASN.1 real value to JSON.

Parameters:
outstream 
void Encode ( Asn1XmlEncoder  buffer,
String  elemName,
String  nsPrefix,
bool  asText 
)

This method encodes an ASN.1 real value according to XER encoding rules. It is for use with extended-XER.

Parameters:
buffer Encode message buffer object
elemName Element name
asText If TRUE, encode special values as text. Otherwise, special values are encoded as empty elements.
override void Encode ( Asn1XmlEncoder  buffer,
System.String  elemName,
System.String  nsPrefix 
) [virtual]

This method encodes an ASN.1 real value according to Obj-Sys encoding rules. The value is encoded as text.

Parameters:
buffer Encode message buffer object
elemName Element name
nsPrefix Element namespace value

Reimplemented from Asn1Type.

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

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

Parameters:
buffer Encode message buffer object
elemName Element name

Reimplemented from Asn1Type.

override void Encode ( Asn1OerEncodeBuffer  buffer  )  [virtual]

Encode this REAL value, according to OER, into the buffer. This method applies to unconstrained REAL values and REAL values that are constrained but not meeting the requirements for encoding using IEEE 754 single or double precision format.

Reimplemented from Asn1Type.

override void Encode ( Asn1PerEncodeBuffer  buffer  )  [virtual]

Parameters:
buffer PER Encode message buffer object

Reimplemented from Asn1Type.

override int Encode ( Asn1BerEncodeBuffer  buffer,
bool  explicitTagging 
) [virtual]

Parameters:
buffer Encode message buffer object
override bool Equals ( System.Object  value  ) 

Determines whether the specified Object is equal to the current Object.

Parameters:
value The Object to compare with the current Object. Object should be instance of Asn1Real.
Returns:
true if the specified Object is equal to the current Object; otherwise, false.
virtual bool Equals ( double  value  )  [virtual]

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

value The double value to compare with the current Object.
Returns:
true if the specified double value is equal to the current Object; otherwise, false.
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.
static System.String NormalizedRealValueToString ( double  value  )  [static]

This method will return a string representation of the normalized REAL value.

The output format is value format [-]X.XXXXE[-]XXX.

The format is the ASN.1 value format for this type. This means it is a "NumericRealValue" as defined in X.680. Additionally, if there is a leading minus sign, there will be no whitespace between it and the first digit of the integer part, making it also an "XMLNumericRealValue".

Parameters:
value value to be normalized and stringified.
Returns:
the string as described above
override System.String ToString (  ) 

This method will return a string representation of the REAL value. The format is the ASN.1 value format for this type..

Member Data Documentation

new readonly Asn1Tag _TAG [static]

The _TAG constant describes the universal tag for this data type (UNIVERSAL 9).

Reimplemented from Asn1Type.

double mValue

This public member variable is where the double 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.
