Constructor Detail

Asn1VarWidthCharString

protected Asn1VarWidthCharString(short typeCode)

The default constructor creates an empty string object.

Parameters:

typeCode - Universal ID code for ASN.1 character string

Asn1VarWidthCharString

protected Asn1VarWidthCharString(java.lang.String data,
                                 short typeCode)

This version of the constructor can be used to set the string value member variable to the given string.

Parameters:

data - Character string

typeCode - Universal ID code for ASN.1 character string

Method Detail

decode

public void decode(Asn1PerDecodeBuffer buffer)
            throws Asn1Exception,
                   java.io.IOException

This method decodes an ASN.1 character string value in accordance with the packed encoding rules (PER). This version of the method assumes no permitted alphabet or size constraints. Decoded characters are assigned as-is to the output string. The decoded result is stored in the public value member variable in the Asn1CharString base class.

Specified by:

decode in interface Asn1TypeIF

Overrides:

decode in class Asn1Type

Parameters:

buffer - Decode message buffer object

Throws:

Asn1Exception

java.io.IOException

decode

public void decode(Asn1PerDecodeBuffer buffer,
                   long lower,
                   long upper)
            throws Asn1Exception,
                   java.io.IOException

This overloaded version of the decode method decodes an ASN.1 character string value in accordance with the packed encoding rules (PER). This version of the method assumes a size constraint is present. A permitted alphabet may be passed, but it will be ignored. The decoded result is stored in the public value member variable in the Asn1CharString base class.

Parameters:

buffer - Decode message buffer object

lower - Effective size constraint lower bound

upper - Effective size constraint upper bound

Throws:

Asn1Exception

java.io.IOException

encode

public void encode(Asn1PerEncodeBuffer buffer)
            throws Asn1Exception,
                   java.io.IOException

This method encodes an ASN.1 character string value in accordance with the packed encoding rules (PER). This version of the method assumes no permitted alphabet or size constraints. The value to encode is stored in the public value member variable in the Asn1CharString base class.

Specified by:

encode in interface Asn1TypeIF

Overrides:

encode in class Asn1Type

Parameters:

buffer - Encode message buffer object

Throws:

Asn1Exception

java.io.IOException

encode

public void encode(Asn1PerEncodeBuffer buffer,
                   long lower,
                   long upper)
            throws Asn1Exception,
                   java.io.IOException

This overloaded version of the encode method encodes an ASN.1 character string value in accordance with the packed encoding rules (PER). This version of the method assumes a size constraint is present. A permitted alphabet may be passed, but it will be ignored. The value to encode is stored in the public value member variable in the Asn1CharString base class.

Parameters:

buffer - Encode message buffer object

lower - Effective size constraint lower bound

upper - Effective size constraint upper bound

Throws:

Asn1Exception

java.io.IOException

decode

public void decode(Asn1OerDecodeBuffer buffer)
            throws java.io.IOException

Decode the value in accordance with OER. Subclasses may override this to add constraint checks after invoking this method to decode the string.

Overrides:

decode in class Asn1Type

Parameters:

buffer -

Throws:

java.io.IOException

encode

public void encode(Asn1OerEncodeBuffer buffer)
            throws java.io.IOException

Encode the value in accordance with OER. We're assuming each char is encoded in a single byte of the same value as the char. Subclasses may override this (e.g. to add constraint checks) and invoke this method to perform the encoding.

Overrides:

encode in class Asn1Type

Parameters:

buffer -

Throws:

java.io.IOException

encode

public void encode(Asn1PerOutputStream out)
            throws Asn1Exception,
                   java.io.IOException

This method encodes an ASN.1 character string value in accordance with the packed encoding rules (PER) directly into the stream. This version of the method assumes no permitted alphabet or size constraints. The value to encode is stored in the public value member variable in the Asn1CharString base class.

Specified by:

encode in interface Asn1TypeIF

Overrides:

encode in class Asn1Type

Parameters:

out - PER Encode message stream object

Throws:

java.io.IOException - Any exception thrown by the Asn1PerOutputStream.

Asn1Exception - Thrown, if operation is failed.

encode

public void encode(Asn1PerOutputStream out,
                   long lower,
                   long upper)
            throws Asn1Exception,
                   java.io.IOException

This overloaded version of the encode method encodes an ASN.1 character string value directly into the stream, in accordance with the packed encoding rules (PER). This version of the method assumes a size constraint is present. A permitted alphabet may be passed, but it will be ignored. The value to encode is stored in the public value member variable in the Asn1CharString base class.

Parameters:

out - PER Encode message stream object

lower - Effective size constraint lower bound

upper - Effective size constraint upper bound

Throws:

java.io.IOException - Any exception thrown by the Asn1PerOutputStream.

Asn1Exception - Thrown, if operation is failed.
