Detailed Description

This class handles the encoding of ASN.1 messages as specified in the XML Encoding (non-XER) by the XML schema standard(generated by asn2xsd).

Constructor & Destructor Documentation

◆ Asn1XmlEncodeBuffer() [1/2]

The default constructor creates an XML encode buffer object with the default size increment and canonical set to false.

◆ Asn1XmlEncodeBuffer() [2/2]

Asn1XmlEncodeBuffer ( int  sizeIncrement)

The parameterized constructor creates an XML encode buffer object with size increment and canonical set to the given values.

Parameters
canonicalBoolean indicating a canonical or non-canonical encoding should be produced as defined in the X.693 standard.
sizeIncrementThe initial size in bytes of an encode buffer. If the buffer becomes full, it will be expanded by this amount. If this parameter is set to zero, the default increment will be used.

Member Function Documentation

◆ BinDump()

override void BinDump ( System.IO.StreamWriter  outs,
System.String  varName 
)
virtual

This method dumps the encoded message in a human-readable format showing a bit trace of all fields to the given print output stream.

Parameters
outsOutput will be written to this stream
varNameName of the Decoded ASN1 Type

Implements Asn1EncodeBuffer.

◆ Copy()

virtual void Copy ( System.String  data)
virtual

This method copies a character string to the encode buffer.

Parameters
qnameAttribute qualified name.
valueAttribute value in string form.

Implements Asn1XmlEncoder.

◆ EncodeBinStrValue()

virtual void EncodeBinStrValue ( byte []  bits,
int  nbits 
)
virtual

This method encodes XML binary string data

Parameters

Implements Asn1XmlXerEncoder.

References Asn1Util.URShift().

◆ EncodeByte()

virtual void EncodeByte ( byte  data)
virtual

This method is used to encode a single byte to the encode buffer. It first converts the byte to a hex character representation and then copies it to the output buffer.

Parameters
dataThe byte value to copy

Implements Asn1XmlXerEncoder.

References Asn1Util.URShift().

◆ EncodeData()

virtual void EncodeData ( System.String  data)
virtual

This method encodes XML string data

Parameters
valueString value to encode

<throws> IOException Any exception thrown by the underlying OutputStream. </throws> <throws> Asn1Exception Thrown, if operation is failed. </throws>

Implements Asn1XmlXerEncoder.

◆ EncodeDoubleValue()

virtual void EncodeDoubleValue ( double  data,
System.String  elemName,
System.String  nsPrefix 
)
virtual

This method encodes an XML REAL (double) value (with start and end tags).

Parameters
dataThe value to be encoded.
elemNameThe name of element. If null, then start and end tags won't be encoded.
Exceptions
Asn1ExceptionThrown, if operation is failed.

Implements Asn1XmlEncoder.

References Asn1XmlUtil.EncodeDouble().

◆ EncodeEmptyElement()

virtual void EncodeEmptyElement ( System.String  elemName,
System.String  nsPrefix,
bool  terminate 
)
virtual

This method encodes an XML empty element tag

Parameters
elemNameThe name of element.
nsPrefixThe namespace prefix of element.

<throws> Asn1Exception Thrown, if operation is failed. </throws>

Implements Asn1XmlEncoder.

References Asn1XmlEncoder_Fields.XMLEND.

◆ EncodeEndDocument()

virtual void EncodeEndDocument ( )
virtual

This method encodes standard trailor information at the end of the XML document.

Implements Asn1XmlXerEncoder.

◆ EncodeEndElement() [1/2]

virtual void EncodeEndElement ( System.String  elemName,
System.String  nsPrefix 
)
virtual

This method encodes an XML end element tag

Parameters
elemNameThe name of element, as String.

Implements Asn1XmlEncoder.

References Asn1XmlEncoder_Fields.XMLEND.

Referenced by Asn1XmlAnyElem.XsdAnySaxHandler.EndElement().

◆ EncodeEndElement() [2/2]

virtual void EncodeEndElement ( System.String  elemName,
System.String  nsPrefix,
bool  indent 
)
virtual

This method encodes an XML end element tag without indenting

Parameters
elemNameThe name of element.

<throws> Asn1Exception Thrown, if operation is failed. </throws>

References Asn1XmlEncoder_Fields.XMLEND.

◆ EncodeHexStrValue()

virtual void EncodeHexStrValue ( byte []  data)
virtual

This method encodes XML hexadecimal string data

Parameters
dataData to encode

<throws> IOException Any exception thrown by the underlying OutputStream. </throws> <throws> Asn1Exception Thrown, if operation is failed. </throws>

Implements Asn1XmlXerEncoder.

◆ EncodeNamedValue()

virtual void EncodeNamedValue ( System.String  valueName,
System.String  elemName,
System.String  nsPrefix 
)
virtual

This method encodes an XML named value (with start and end tags)

Implements Asn1XmlEncoder.

◆ EncodeNamedValueElement()

virtual void EncodeNamedValueElement ( System.String  valueName)
virtual

This method encodes an XML named value element tag
