Detailed Description

This class represents the ASN.1 BOOLEAN built-in type.

Constructor & Destructor Documentation

Asn1Boolean (  ) 

The default constructor sets the boolean value to false.

Asn1Boolean ( bool  value_  ) 

This constructor creates a boolean object from a boolean value.

Parameters:
value_ Boolean value

Member Function Documentation

override void Decode ( Asn1PerDecodeBuffer  buffer  )  [virtual]
This method decodes an ASN.1 boolean value using
the Packed Encoding Rules (PER).
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 boolean value including the UNIVERSAL
tag value and length if explicit tagging is specified. This overloaded version uses the Basic Encoding Rules (BER) or the Distinguished Encoding Rules (DER).
The decoded result is stored in the public member mValue
in this object.
Parameters:
buffer Decode message buffer object
explicitTagging Flag indicating element is explicitly tagged
implicitLength Length of contents if implicit
Returns:
Decoded boolean value

Reimplemented from Asn1Type.

virtual void DecodeXER ( System.String  buffer,
System.String  attrs 
) [virtual]

This method decodes an ASN.1 boolean value using the XML encoding rules (XER).

Parameters:
buffer String containing data to be decoded
attrs Attributes string from element tag
override void DecodeXML ( System.String  buffer,
System.String  attrs 
)

This method decodes an ASN.1 boolean 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 an ASN.1 boolean value using the Packed Encoding Rules (PER).

Also throws any exception thrown by the underlying Asn1PerOutputStream.

Parameters:
outs PER Encode message 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 boolean 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 the underlying System.IO.Stream object.

Parameters:
outs BER Output Stream object
explicitTagging Flag indicating explicit tagging should be done
Exceptions:
Asn1Exception Thrown, if operation is failed.

Reimplemented from Asn1Type.

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

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

Parameters:
buffer Encode message buffer object
elemName Element name for optional surrounding element.
nsPrefix XML element name space prefix
asText If true, encode as text. Otherwise, encode as an empty element.
virtual void Encode ( Asn1XmlEncoder  buffer,
System.String  elemName,
System.String  nsPrefix 
) [virtual]

This method encodes an ASN.1 boolean value according to the Obj-Sys XML encoding rules. It encodes the value as XML text.

Parameters:
buffer Encode message buffer object
elemName Element name for optional surrounding element.
nsPrefix Element namespace prefix value
virtual void Encode ( Asn1XerEncodeBuffer  buffer  )  [virtual]

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

Parameters:
buffer Encode message buffer object
override void Encode ( Asn1XerEncoder  buffer,
System.String  elemName 
) [virtual]

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

Parameters:
buffer Encode message buffer object
elemName Element name

Reimplemented from Asn1Type.

override void Encode ( Asn1PerEncodeBuffer  buffer  )  [virtual]

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

Parameters:
buffer PER Encode message buffer object
Returns:
Length of component or negative status value

Reimplemented from Asn1Type.

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

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

Parameters:
buffer Encode message buffer object
explicitTagging Flag indicating explicit tagging should be done
Returns:
Length (in octets) of encoded component

Reimplemented from Asn1Type.

virtual void EncodeAttribute ( Asn1XmlEncoder  buffer,
System.String  attrName 
) [virtual]

This method encodes an ASN.1 boolean value using the XML Encoding as specified in the W3C XML schema standard(asn2xsd).

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

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

Parameters:
value The Object to compare with the current Object. Object should be instance of Asn1Boolean.
Returns:
true if the specified Object is equal to the current Object; otherwise, false.
virtual bool Equals ( bool  value  )  [virtual]

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

Parameters:
value The bool value to compare with the current Object.
Returns:
true if the specified bool 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 void setTrueEncodedByte ( byte  b  )  [static]

This method sets the byte value that represents the boolean value TRUE. If a zero byte (0x00) is passed, the value is transparently set to 0xFF, the valid representation for BER, CER, and DER.

Parameters:
b The byte value to set.
override System.String ToString (  ) 

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

Returns:
Stringified representation of the value

Member Data Documentation

new readonly Asn1Tag _TAG [static]

The _TAG constant describes the universal tag for this data type (UNIVERSAL 1).

Reimplemented from Asn1Type.

readonly Asn1Boolean FALSE_VALUE = new Asn1Boolean(false) [static]

The FALSE_VALUE constant represents a boolean FALSE value.

bool mValue

This public member variable is where the boolean 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.

readonly Asn1Boolean TRUE_VALUE = new Asn1Boolean(true) [static]

The TRUE_VALUE constant represents a boolean TRUE value.
