## org.bouncycastle.asn1
Class ASN1TaggedObject

    java.lang.Object
      org.bouncycastle.asn1.ASN1Encodable
          org.bouncycastle.asn1.DERObject
              org.bouncycastle.asn1.ASN1TaggedObject

All Implemented Interfaces:
  DEREncodable, DERTags

Direct Known Subclasses:
  DERTaggedObject

public abstract class ASN1TaggedObject
extends DERObject

ASN.1 TaggedObject - in ASN.1 nottation this is any object proceeded by a [n] where n is some number - these are assume to follow the construction rules (as with sequences).

Constructor Detail

### ASN1TaggedObject

    public ASN1TaggedObject(int tagNo,
                            DEREncodable obj)

Parameters:
  `tagNo` - the tag number for this object.
  `obj` - the tagged object.

### ASN1TaggedObject

    public ASN1TaggedObject(boolean explicit,
                            int tagNo,
                            DEREncodable obj)

Parameters:
  `explicit` - true if the object is explicitly tagged.
  `tagNo` - the tag number for this object.
  `obj` - the tagged object.

Method Detail

### getInstance

    public static ASN1TaggedObject getInstance(ASN1TaggedObject obj,
                                               boolean explicit)

### equals

    public boolean equals(java.lang.Object o)

  Specified by:
    `equals` in class `DERObject`

### hashCode

    public int hashCode()

  Specified by:
    `hashCode` in class `DERObject`

### getTagNo

    public int getTagNo()

### isExplicit

    public boolean isExplicit()

  return whether or not the object may be explicitly tagged.

  Note: if the object has been read from an input stream, the only time you can be sure if isExplicit is returning the true state of affairs is if it returns false. An implicitly tagged object may appear to be explicitly tagged, so you need to understand the context under which the reading was done as well, see getObject below.

### isEmpty

    public boolean isEmpty()

### getObject

    public DERObject getObject()

  return whatever was following the tag.

  Note: tagged objects are generally context dependent if you're trying to extract a tagged object you should be going via the appropriate getInstance method.
