Constructor Detail

ASN1GenericConstructed

public ASN1GenericConstructed(int tag)

Creates a new, empty ASN.1 constructed object (that is, one with no components), which has the given tag and the context-specific tag class.

ASN1GenericConstructed

public ASN1GenericConstructed(int tag,
                              int tagClass)

Creates a new, empty ASN.1 structure (that is, with no components), with the given tag and tag class.

ASN1GenericConstructed

public ASN1GenericConstructed(ASN1Object o,
                              int tag)

Construct an EXPLICIT wrapper around an object with the given tag and the context-specific tag class.

ASN1GenericConstructed

public ASN1GenericConstructed(ASN1Object o,
                              int tag,
                              int tagClass)

Construct an EXPLICIT wrapper around an object with the given tag and tag class.

ASN1GenericConstructed

public ASN1GenericConstructed(java.util.Vector el,
                              int tag)

Creates a new ASN.1 constructed object, with the given components vector and tag, and the context-specific tag class. This constructor may be used to perform implicit tagging.

ASN1GenericConstructed

public ASN1GenericConstructed(java.util.Vector el,
                              int tag,
                              int tagClass)

Creates a new ASN.1 constructed object, with the given components vector, tag, and tag class. This constructor may be used to perform implicit tagging.

Parameters:

el - A vector which contains the components. Each element must be an instance of ASN1Object.

ASN1GenericConstructed

public ASN1GenericConstructed(java.io.InputStream is)
                       throws java.io.IOException

Throws:

java.io.IOException

Method Detail

getHeader

public ASN1Header getHeader()

Specified by:

getHeader in interface ASN1TaggedObject

getTag

public int getTag()

getTagClass

public int getTagClass()

elements

public java.util.Vector elements()

Returns the components of this ASN.1 constructed object, as a vector, each element of which is an instance of ASN1Object.

Specified by:

elements in interface ASN1Constructed

size

public int size()

Returns the number of components of this ASN.1 constructed object.

Specified by:

size in interface ASN1Constructed

elementAt

public ASN1Object elementAt(int n)

Returns the component of this ASN.1 constructed object at the specified index.

Specified by:

elementAt in interface ASN1Constructed

firstElement

public ASN1Object firstElement()

Returns the first component of this ASN.1 constructed object.

lastElement

public ASN1Object lastElement()

Returns the last component of this ASN.1 constructed object.

addElement

public void addElement(ASN1Object o)

Appends the given object to this ASN.1 constructed object, making it the last component.

setEncodingType

public void setEncodingType(int encodingType)

Set the encoding type. This is only needed if this object is a representation of an implicitly tagged set and you are using a DER encoding. Use one of the constants defined in ASN1Set: BER, DER_SET, DER_SET_OF. The default is BER, which means no sorting is done (this is appropriate for implicitly tagged DER sequences and explicitly tagged objects).

getEncodingType

public int getEncodingType()

Returns the encoding type.

See Also:

setEncodingType(int)

toString
