Detailed Description

This is a container class for holding an ASN.1 open type value.

Where the data is internally stored and how it is interpreted is controlled by a "dataEncoding" field. You can specify the data encoding when creating the object. It will also be set when decoding. The following explains the possible data encodings:

Note especially that the data encoding indicates the encoding rules used to encode the actual value. That result is typically encoded as part of some larger encoding. The data encoding does NOT indicate the rules used for that larger encoding. For example, using an xmlhstring representation, XER and JSON will encode an open type that was previously encoded using any arbitrary encoding rules. When decoding such data, the data encoding will be UNKNOWN, not XER nor JSON.

Constructor & Destructor Documentation

◆ Asn1OpenType() [1/8]

This constructor creates an empty type that can be used in a Decode method call to receive an encoded value. The data encoding is UNKNOWN.

◆ Asn1OpenType() [2/8]

Asn1OpenType ( byte []  data)

This constructor initializes an open type from the given byte array. The array is assumed to contain a previously encoded message component. The data encoding is UNKNOWN.

Parameters
dataByte array containing a previously encoded message component.

◆ Asn1OpenType() [3/8]

Asn1OpenType ( byte []  data,
int  encoding 
)

This constructor initializes an open type from the given byte array. The array is assumed to contain a previously encoded message component.

Parameters
dataByte array containing a previously encoded value.
encodingThe encoding that describes the meaning of data. Any of the encodings other than JSON.

◆ Asn1OpenType() [4/8]

Asn1OpenType ( byte []  data,
int  offset,
int  nbytes 
)

This constructor initializes the open type from a portion of the given byte array. A new byte array is created starting at the given offset and consisting of the given number of bytes. The encoding is UNKNOWN.

Parameters
dataByte array containing a previously encoded value.
offsetThe offset in array at which to begin copy.
nbytesNumber of bytes to copy from target array

◆ Asn1OpenType() [5/8]

Asn1OpenType ( byte []  data,
int  offset,
int  nbytes,
int  encoding 
)

This constructor initializes the open type from a portion of the given byte array. A new byte array is created starting at the given offset and consisting of the given number of bytes. /p>

Parameters
dataByte array containing a previously encoded value.
encodingStarting offset in data from which to copy bytes
nbytesNumber of bytes to copy from target array
offsetThe encoding that describes the meaning of data. Any of the encodings other than JSON.

◆ Asn1OpenType() [6/8]

This constructor initializes an open type using an encoded component. This can be used if a header (for example, a ROSE header) is being prepended to a pre-encoded component. The data encoding is derived from the type of Asn1EncodeBuffer given, and is possibly UNKNOWN.

Parameters
bufferReference to encode buffer into which component type was encoded.

References Asn1EncodeBuffer.MsgCopy, and Asn1EncodeBuffer.MsgLength.

◆ Asn1OpenType() [7/8]

Asn1OpenType ( string  data,
int  encoding 
)

Convenience constructor. Same as Asn1OpenType(data.ToCharArray(), encoding)

◆ Asn1OpenType() [8/8]

Asn1OpenType ( char []  data,
int  encoding 
)

Create Asn1OpenType on the given character data. /p>

Parameters
dataThe character data array.
encodingThe encoding. Either XER or JSON. If JSON, data is taken to be the JSON encoding of the actual value. The array is not copied, so beware using it after passing it here. The "mValue" field will be assigned null. If XER, data is taken to be the XER encoding of the actual value. The "mValue" field will be assigned the UTF-8 character encoding of the given characters.

Member Function Documentation

◆ Decode() [1/3]

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

This method decodes an ASN.1 open type value. The data encoding will be set to BER.

Parameters
bufferDecode message buffer object
explicitTaggingFlag indicating element is explicitly tagged
implicitLengthLength of contents if implicit

Reimplemented from Asn1OctetString.

Referenced by Asn1OpenExt.DecodeComponent(), Asn1OpenExt.DecodeOpenType(), Asn1OpenExt.SetOpenType(), and Asn1OpenExt.ShrinkArray().

◆ Decode() [2/3]

override void Decode ( Asn1PerDecodeBuffer  buffer)
virtual

This method decodes an ASN.1 open type value using the packed encoding rules (PER). The data encoding will be set to PER.

Parameters
bufferDecode message buffer object

Reimplemented from Asn1OctetString.

◆ Decode() [3/3]

override void Decode ( Asn1OerDecodeBuffer  buffer)
virtual

This method decodes an ASN.1 open type value using the Octet Encoding Rules (OER). This object will subsequently contain the encoding of the open type (which should be OER).

Reimplemented from Asn1OctetString.

◆ Encode() [1/9]

override int Encode ( Asn1BerEncodeBuffer  buffer,
bool  explicitTagging 
)
virtual

This method encodes an ASN.1 open type value. The value is assumed to be an already-encoded BER message component and will be copied to the encoded buffer. An optimization is available in which no copy will performed if the encoded component is already present in the encode buffer. This is done if the form of constructor specifiying only a component length is used.

Parameters
bufferEncode message buffer object
explicitTaggingFlag indicating element is explicitly tagged
Returns
Length of encoded component

Reimplemented from Asn1OctetString.

Referenced by Asn1OpenExt.Encode(), and Asn1OpenExt.ToString().

◆ GetSaxHandler() [1/2]

virtual Asn1XerSaxHandler GetSaxHandler ( )
virtual

This method returns the Asn1XerOpenType.SaxHandler class instance used for ASN.1 XER encoding. If this is the first invocation of any of the GetSaxHandler methods on this object, the returned handler will capture the outer element start/end tags.

int  encoding 
)

Sets the character data for the open type and assigns the data encoding to the given encoding.

Parameters
dataThe character data that make up an encoding of the actual value.
encodingPermissible values are JSON and XER. If XER, the given data will be converted to bytes using UTF-8 and held in the "mValue" field. If JSON, the given data will be held as-is. The array will not be copied. The "mValue" field will be assigned null.

◆ ToString()

override System.String ToString ( )

This method will return a string representation of the open type value. If the data encoding is XER or JSON, the string will consist of the corresponding characters (in the case of XER, the byte data is converted to characters using UTF-8).
