org.bouncycastle.asn1.DERNumericString
All Implemented Interfaces:
ASN1Encodable, ASN1String
public class DERNumericString
extends ASN1Primitive
implements ASN1String
DER NumericString object - this is an ascii string of characters {0,1,2,3,4,5,6,7,8,9, }.

  • Constructor Details

    • DERNumericString

      public DERNumericString​(String string)
      basic constructor - without validation..

    • DERNumericString

      public DERNumericString​(String string, boolean validate)
      Constructor with optional validation.
      Parameters:
      string - the base string to wrap.
      validate - whether or not to check the string.
      Throws:
      IllegalArgumentException - if validate is true and the string contains characters that should not be in a NumericString.

  • Method Details

    • getInstance

      public static DERNumericString getInstance​(Object obj)
      return a Numeric string from the passed in object
      Throws:
      IllegalArgumentException - if the object cannot be converted.

    • getInstance

      public static DERNumericString getInstance​(ASN1TaggedObject obj, boolean explicit)
      return an Numeric String from a tagged object.
      Parameters:
      obj - the tagged object holding the object we want
      explicit - true if the object is meant to be explicitly tagged false otherwise.
      Throws:
      IllegalArgumentException - if the tagged object cannot be converted.

    • getString

      public String getString()
      Specified by:
      getString in interface ASN1String

    • toString

      public String toString()
      Description copied from class: Object
      Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression: 
         getClass().getName() + '@' + Integer.toHexString(hashCode())

      See Writing a useful toString method if you intend implementing your own toString method.

      Overrides:
      toString in class Object
      Returns:
      a printable representation of this object.

    • getOctets

      public byte[] getOctets()

    • hashCode

      public int hashCode()
      Description copied from class: Object
      Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

      Note that hash values must not change over time unless information used in equals comparisons also changes.

      See Writing a correct hashCode method if you intend implementing your own hashCode method.

      Specified by:
      hashCode in class ASN1Primitive
      Returns:
      this object's hash code.
      See Also:
      Object.equals(java.lang.Object)

    • isNumericString

      public static boolean isNumericString​(String str)
      Return true if the string can be represented as a NumericString ('0'..'9', ' ')
      Parameters:
      str - string to validate.
      Returns:
      true if numeric, fale otherwise.
