## Class ASN1Primitive

- java.lang.Object
- - org.bouncycastle.asn1.ASN1Object
  - - org.bouncycastle.asn1.ASN1Primitive

- All Implemented Interfaces:
    ASN1Encodable, Encodable
  Direct Known Subclasses:
    ASN1Absent, ASN1BitString, ASN1BMPString, ASN1Boolean, ASN1Enumerated, ASN1External, ASN1GeneralizedTime, ASN1GeneralString, ASN1GraphicString, ASN1IA5String, ASN1Integer, ASN1Null, ASN1NumericString, ASN1ObjectDescriptor, ASN1ObjectIdentifier, ASN1OctetString, ASN1PrintableString, ASN1RelativeOID, ASN1Sequence, ASN1Set, ASN1T61String, ASN1TaggedObject, ASN1UniversalString, ASN1UTCTime, ASN1UTF8String, ASN1VideotexString, ASN1VisibleString

      public abstract class ASN1Primitive
      extends ASN1Object

  Base class for ASN.1 primitive objects. These are the actual objects used to generate byte encodings.

    - #### encodeTo

          public void encodeTo(java.io.OutputStream output)
                        throws java.io.IOException

      Overrides:
        `encodeTo` in class `ASN1Object`
      Throws:
        `java.io.IOException`

    - #### encodeTo

          public void encodeTo(java.io.OutputStream output,
                               java.lang.String encoding)
                        throws java.io.IOException

      Overrides:
        `encodeTo` in class `ASN1Object`
      Throws:
        `java.io.IOException`

    - #### fromByteArray

          public static ASN1Primitive fromByteArray(byte[] data)
                                             throws java.io.IOException

      Parse an ASN.1 (BER) encoding from a byte array. Checks there are no extra bytes following the encoding.
      Parameters:
        `data` - the byte array to parse.
      Returns:
        the base ASN.1 object parsed from the byte array.
      Throws:
        `java.io.IOException` - if there is a problem parsing the data, or parsing did not exhaust the available data.

    - #### fromStream

          public static ASN1Primitive fromStream(java.io.InputStream input)
                                          throws java.io.IOException

      Parse the first ASN.1 (BER) encoding from an `InputStream`.The stream is not closed by this method and may contain further data beyond the first ASN.1 encoding.
      Parameters:
        `data` - the stream to parse.
      Returns:
        the base ASN.1 object parsed from the stream.
      Throws:
        `java.io.IOException` - if there is a problem parsing the data.
