public class InfoTypeAndValue

extends oracle.security.crypto.cert.AttributeTypeAndValue

CMP base class for information type and values.

The CMP specification lists several pairs of information types and values (optional) but, technically, any valid pair of ASN1ObjectID and ASN1Object may be used. For ease of use, the classes representing the type an value pairs defined in CMP provide methods for accessing their values that are tailored to their particular structures. For this reason, it is desirable that an information type an dvalue be cast-able to its subclass type after being input from, for example, a stream.

To facilitate this behavior, a static inputInstance(java.io.InputStream) method is provided in the InfoTypeAndValue base class. For defined/recognized controls, the method returns an instance of the appropriate InfoTypeAndValue subclass, which can then be cast to its real type. For all other valid type and value pairs, an instance of the InfoTypeAndValue base class is returned.

Field Detail

encoded

protected boolean encoded

This field is used for coordinating ASN.1 output with the superclass. If the subclass representation of the value has been modified, encoded must be set to false. When the new value has been communicated to the superclass, encoded must be set to true.

The initial value is false.

decoded

protected boolean decoded

This field is used for coordinating ASN.1 input with the superclass. If the superclass representation of the value has been modified, decoded must be set to false. When the new value has been communicated to the subclass, decoded must be set to true.

The initial value is true.

Constructor Detail

InfoTypeAndValue

public InfoTypeAndValue()

Creates a new, empty information type and value.

InfoTypeAndValue

public InfoTypeAndValue(oracle.security.crypto.asn1.ASN1ObjectID type,
                        oracle.security.crypto.asn1.ASN1Object value)

InfoTypeAndValue

public InfoTypeAndValue(oracle.security.crypto.asn1.ASN1ObjectID type)

InfoTypeAndValue

public InfoTypeAndValue(java.io.InputStream is)
                 throws java.io.IOException

Throws:

java.io.IOException

Method Detail

inputInstance

public static InfoTypeAndValue inputInstance(java.io.InputStream is)
                                      throws java.io.IOException

Creates a new CMP InfoTypeAndValue by reading its encoding from the given input stream.

Parameters:

is - the input stream.

Throws:

java.io.IOException - if an I/O error occurs during input, or the encoding does not have the correct format.

getType

public oracle.security.crypto.asn1.ASN1ObjectID getType()

Returns the type.

Overrides:

getType in class oracle.security.crypto.cert.AttributeTypeAndValue

Returns:

the information type

getValue

public oracle.security.crypto.asn1.ASN1Object getValue()

Returns the value.

Overrides:

getValue in class oracle.security.crypto.cert.AttributeTypeAndValue

Returns:

the information value

setValue

public void setValue(oracle.security.crypto.asn1.ASN1Object value)

Sets the value.

Overrides:

setValue in class oracle.security.crypto.cert.AttributeTypeAndValue

encodeValue

protected void encodeValue()

Encodes this control's fields as an ASN1Object for the baseclass.

Subclasses must override this method to properly test and set the encoded field, and invoke the superclass setValue(oracle.security.crypto.asn1.ASN1Object) method to set the encoded structure.

decodeValue

protected void decodeValue()

Decodes the baseclass' ASN1Object value to populate this control's fields.

Subclasses must override this method to invoke the getValue() method to get the structure to decode, and properly test and set the decoded field.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

input

public void input(java.io.InputStream is)
           throws java.io.IOException

Defines this attribute type-value pair by reading its encoding from the given input stream.

Specified by:

input in interface oracle.security.crypto.util.Streamable

Overrides:

input in class oracle.security.crypto.cert.AttributeTypeAndValue

Parameters:

is - the input stream

Throws:

java.io.IOException

output

public void output(java.io.OutputStream os)
            throws java.io.IOException

Specified by:

output in interface oracle.security.crypto.util.Streamable

Overrides:

output in class oracle.security.crypto.cert.AttributeTypeAndValue

Throws:

java.io.IOException

length

public int length()

Specified by:

length in interface oracle.security.crypto.util.Streamable

Overrides:

length in class oracle.security.crypto.cert.AttributeTypeAndValue
