public X500DistinguishedName()

The basic constructor. Object is special, because it has no superclass, so there is no call to super().

public X500DistinguishedName(byte[] encoded)
            throws IOException

public X500DistinguishedName(InputStream encoded)
            throws IOException

public X500DistinguishedName(String name)

public boolean containsComponent(OID oid,
                                 String value)

public int countComponents()

public boolean equals(Object o)

Determine whether this Object is semantically equal to another Object.

There are some fairly strict requirements on this method which subclasses must follow:

• It must be transitive. If a.equals(b) and b.equals(c), then a.equals(c) must be true as well.
• It must be symmetric. a.equals(b) and b.equals(a) must have the same value.
• It must be reflexive. a.equals(a) must always be true.
• It must be consistent. Whichever value a.equals(b) returns on the first invocation must be the value returned on all later invocations.
• a.equals(null) must be false.
• It must be consistent with hashCode(). That is, a.equals(b) must imply a.hashCode() == b.hashCode(). The reverse is not true; two objects that are not equal may have the same hashcode, but that has the potential to harm hashing performance.

This is typically overridden to throw a ClassCastException if the argument is not comparable to the class performing the comparison, but that is not a requirement. It is legal for a.equals(b) to be true even though a.getClass() != b.getClass(). Also, it is typical to never cause a NullPointerException.

In general, the Collections API (java.util) use the equals method rather than the == operator to compare objects. However, IdentityHashMap is an exception to this rule, for its own good reasons.

The default implementation returns this == o.

Specified by:

equals in interface Principal

Overrides:

equals in interface Object

Parameters:

Returns:

whether this Object is semantically equal to another

Object.hashCode()

public String getComponent(OID oid)

public String getComponent(OID oid,
                           int rdn)

public byte[] getDer()

public String getName()

Specified by:

getName in interface Principal

public int hashCode()

Get a value that represents this Object, as uniquely as possible within the confines of an int.

There are some requirements on this method which subclasses must follow:

• Semantic equality implies identical hashcodes. In other words, if a.equals(b) is true, then a.hashCode() == b.hashCode() must be as well. However, the reverse is not necessarily true, and two objects may have the same hashcode without being equal.
• It must be consistent. Whichever value o.hashCode() returns on the first invocation must be the value returned on all later invocations as long as the object exists. Notice, however, that the result of hashCode may change between separate executions of a Virtual Machine, because it is not invoked on the same object.

Notice that since hashCode is used in Hashtable and other hashing classes, a poor implementation will degrade the performance of hashing (so don't blindly implement it as returning a constant!). Also, if calculating the hash is time-consuming, a class may consider caching the results.

The default implementation returns System.identityHashCode(this)

Specified by:

hashCode in interface Principal

Overrides:

hashCode in interface Object

Returns:

the hash code for this Object

Object.equals(Object), System.identityHashCode(Object)

public void newRelativeDistinguishedName()

public void putComponent(OID oid,
                         String value)

public void putComponent(String name,
                         String value)

public void setUnmodifiable()

public int size()

public String toString()

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() and such.

It is typical, but not required, to ensure that this method never completes abruptly with a RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

Specified by:

toString in interface Principal

Overrides:

toString in interface Object

Returns:

the String representing this Object, which may be null

getClass(), Object.hashCode(), Class.getName(), Integer.toHexString(int)
