targets

private ASN1Sequence targets

Constructor Detail

TargetInformation

private TargetInformation(ASN1Sequence seq)

Constructor from a ASN1Sequence.

Parameters:

seq - The ASN1Sequence.

Throws:

java.lang.IllegalArgumentException - if the sequence does not contain correctly encoded Targets elements.

TargetInformation

public TargetInformation(Targets targets)

Constructs a target information from a single targets element. According to RFC 3281 only one targets element must be produced.

Parameters:

targets - A Targets instance.

TargetInformation

public TargetInformation(Target[] targets)

According to RFC 3281 only one targets element must be produced. If multiple targets are given they must be merged in into one targets element.

Parameters:

targets - An array with Targets.

Method Detail

getInstance

public static TargetInformation getInstance(java.lang.Object obj)

Creates an instance of a TargetInformation from the given object.

obj can be a TargetInformation or a ASN1Sequence

Parameters:

obj - The object.

Returns:

A TargetInformation instance.

Throws:

java.lang.IllegalArgumentException - if the given object cannot be interpreted as TargetInformation.

getTargetsObjects

public Targets[] getTargetsObjects()

Returns the targets in this target information extension.

Returns:

Returns the targets.

toASN1Object

public DERObject toASN1Object()

Produce an object suitable for an ASN1OutputStream. Returns:

          SEQUENCE OF Targets
 

According to RFC 3281 only one targets element must be produced. If multiple targets are given in the constructor they are merged into one targets element. If this was produced from a ASN1Sequence the encoding is kept.

Specified by:

toASN1Object in class ASN1Encodable

Returns:

a DERObject
