Method Detail

### getInstance

    public static DERBoolean getInstance(java.lang.Object obj)

  return a boolean from the passed in object.

  Throws:
    `java.lang.IllegalArgumentException` - if the object cannot be converted.

### getInstance

    public static DERBoolean getInstance(boolean value)

  return a DERBoolean from the passed in boolean.

### getInstance

    public static DERBoolean getInstance(ASN1TaggedObject obj,
                                         boolean explicit)

  return a Boolean 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:
    `java.lang.IllegalArgumentException` - if the tagged object cannot be converted.

### isTrue

    public boolean isTrue()

### equals

    public boolean equals(java.lang.Object o)

  Overrides:
    `equals` in class `java.lang.Object`
