Method Detail

getInstance

public static Field getInstance(ASN1Object object)
                         throws CodingException

Deprecated.

Returns the field specified in the ASN.1 object argument.

Parameters:

object - the ASN.1 representation of the field

Note

Precondition: Must be recognizable by one of the implementations of Field.

Returns:

a Field interface object

Throws:

CodingException - if problems occur when parsing object (for example, if object is illformed

java.lang.IllegalArgumentException - if the field is defined with a Gaussian Normal Basis
