DER NumericString object - this is an ascii string of characters {0,1,2,3,4,5,6,7,8,9, }. ASN.1 NUMERIC-STRING object.

This is an ASCII string of characters {0,1,2,3,4,5,6,7,8,9} + space.

See X.680 section 37.2.

Explicit character set escape sequences are not allowed.

Return the length of the encoding this object will produce.

Returns:int

the length of the object's encoding.

obj:Object

a DERNumericString or an object that can be converted into one.

Returns:DERNumericString

getStringback to summary
public String getString()

Implements org.bouncycastle.asn1.ASN1String.getString.

Doc from org.bouncycastle.asn1.ASN1String.getString.

Return a Java String representation of this STRING type's content.

Returns:String

a Java String representation of this STRING.

hashCodeback to summary
public int hashCode()

Implements abstract org.bouncycastle.asn1.ASN1Primitive.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object

isConstructedback to summary
pack-priv boolean isConstructed()

Implements abstract org.bouncycastle.asn1.ASN1Primitive.isConstructed.

Doc from org.bouncycastle.asn1.ASN1Primitive.isConstructed.

Return true if this objected is a CONSTRUCTED one, false otherwise.

Returns:boolean

true if CONSTRUCTED bit set on object's tag, false otherwise.

toStringback to summary
public String toString()

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object.

Returns:String

a string representation of the object
