asn1Equalsback to summary
pack-priv abstract boolean asn1Equals(ASN1Primitive o)

Equality (similarity) comparison for two ASN1Primitive objects.

encodeback to summary
pack-priv abstract void encode(ASN1OutputStream out) throws IOException
encodedLengthback to summary
pack-priv abstract int encodedLength() throws IOException

Return the length of the encoding this object will produce.

Returns:int

the length of the object's encoding.

Exceptions
IOException:
if the encoding length cannot be calculated.
equalsback to summary
public final boolean equals(Object o)

Overrides org.bouncycastle.asn1.ASN1Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
o:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

fromByteArrayback to summary
public static ASN1Primitive fromByteArray(byte[] data) throws IOException

Create a base ASN.1 object from a byte stream.

Parameters
data:byte[]

the byte stream to parse.

Returns:ASN1Primitive

the base ASN.1 object represented by the byte stream.

Exceptions
IOException:
if there is a problem parsing the data, or parsing the stream did not exhaust the available data.
hashCodeback to summary
public abstract int hashCode()

Overrides org.bouncycastle.asn1.ASN1Object.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 abstract boolean 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.
