Method Detail

getElementType

public Class getElementType()

Returns the Java class representing the ASN.1 type of the elements in this collection.

Returns:

The ASN.1 type of the elements in this collection.

newElement

public ASN1Type newElement()

Creates and returns a new instance of the class passed to the constructor of this instance. The freshly created instance is added to this instance automatically.

If no new instance can be created then an IllegalStateException is thrown.

Decoders should call this method in order to create additional elements on decoding. Subclasses may use this method to keep track on elements added to them.

Returns:

A new instance of the element type of this sequence.

Throws:

IllegalStateException - if no new instance could be created.
