CertPath

extends Object
implements Serializable
java.lang.Object
   ↳ java.security.cert.CertPath

Class Overview

An immutable certificate path that can be validated. All certificates in the path are of the same type (i.e., X509).

A CertPath can be represented as a byte array in at least one supported encoding scheme (i.e. PkiPath or PKCS7) when serialized.

When a List of the certificates is obtained it must be immutable.

A CertPath must be thread-safe without requiring coordinated access.

Summary

Nested Classes
class CertPath.CertPathRep The alternate Serializable class to be used for serialization and deserialization on CertPath objects. 
Protected Constructors
CertPath(String type)
Creates a new CertPath instance for the specified certificate type.
Public Methods
boolean equals(Object other)
Returns true if Certificates in the list are the same type and the lists are equal (and by implication the certificates contained within are the same).
abstract List<? extends Certificate> getCertificates()
Returns an immutable List of the Certificates contained in the CertPath.
abstract byte[] getEncoded(String encoding)
Returns an encoding of the CertPath using the specified encoding.
abstract byte[] getEncoded()
Returns an encoding of the CertPath using the default encoding.
abstract Iterator<String> getEncodings()
Returns an Iterator over the supported encodings for a representation of the certificate path.
String getType()
Returns the type of Certificate in this instance.
int hashCode()
Overrides Object.hashCode().
String toString()
Returns a String representation of this CertPath instance.
Protected Methods

Protected Constructors

protected CertPath (String type)

Since: API Level 1

Creates a new CertPath instance for the specified certificate type.

Parameters
type the certificate type.

Public Methods

public boolean equals (Object other)

Since: API Level 1

Returns true if Certificates in the list are the same type and the lists are equal (and by implication the certificates contained within are the same).

Parameters
other CertPath to be compared for equality.
Returns
  • true if the object are equal, false otherwise.

public abstract List<? extends Certificate> getCertificates ()

Since: API Level 1

Returns an immutable List of the Certificates contained in the CertPath.

Returns
  • a list of Certificates in the CertPath.

public abstract byte[] getEncoded (String encoding)

Since: API Level 1

Returns an encoding of the CertPath using the specified encoding.

Parameters
encoding encoding that should be generated.
Returns
  • default encoding of the CertPath.
Throws
CertificateEncodingException if the encoding fails.

public abstract byte[] getEncoded ()

Since: API Level 1

Returns an encoding of the CertPath using the default encoding.

Returns
  • default encoding of the CertPath.
Throws
CertificateEncodingException if the encoding fails.

public abstract Iterator<String> getEncodings ()

Since: API Level 1

Returns an Iterator over the supported encodings for a representation of the certificate path.

Returns
  • Iterator over supported encodings (as Strings).

public String getType ()

Since: API Level 1

Returns the type of Certificate in this instance.

Returns
  • the certificate type.

public int hashCode ()

Since: API Level 1

Overrides Object.hashCode(). The function is defined as follows: 

 hashCode = 31 * path.getType().hashCode() +
 path.getCertificates().hashCode();

Returns
  • the hash code for this instance.

public String toString ()

Since: API Level 1

Returns a String representation of this CertPath instance. It is the result of calling toString on all Certificates in the List.

Returns
  • a string representation of this instance.

Protected Methods

protected Object writeReplace ()

Since: API Level 1

Returns an alternate object to be serialized.

Returns
  • an alternate object to be serialized.
Throws
ObjectStreamException if the creation of the alternate object fails.
