Class PKIXBuilderParameters

Implemented Interfaces:
CertPathParameters, Cloneable
public class PKIXBuilderParameters
extends PKIXParameters
Parameters for building certificate paths using the PKIX algorithm.
Since:
1.4
See Also:
CertPathBuilder

Constructor Summary

PKIXBuilderParameters(Set trustAnchors, CertSelector targetConstraints)
Create a new PKIXBuilderParameters object, populating the trusted certificates set with the elements of the given set, each of which must be a TrustAnchor.
PKIXBuilderParameters(KeyStore keystore, CertSelector targetConstraints)
Create a new PKIXBuilderParameters object, populating the trusted certificates set with all X.509 certificates found in the given key store.

Method Summary

int
getMaxPathLength()
Returns the maximum length of certificate paths to build.
void
setMaxPathLength(int maxPathLength)
Sets the maximum length of certificate paths to build.
String
toString()
Returns a printable representation of these parameters.

Constructor Details

PKIXBuilderParameters

public PKIXBuilderParameters(Set trustAnchors,
                             CertSelector targetConstraints)
            throws InvalidAlgorithmParameterException
Create a new PKIXBuilderParameters object, populating the trusted certificates set with the elements of the given set, each of which must be a TrustAnchor.
Parameters:
trustAnchors - The set of trust anchors.
targetConstraints - The target certificate constraints.
Throws:
InvalidAlgorithmParameterException - If there are no certificates in the set.
NullPointerException - If trustAnchors is null.
ClassCastException - If every element in trustAnchors is not a TrustAnchor.

PKIXBuilderParameters

public PKIXBuilderParameters(KeyStore keystore,
                             CertSelector targetConstraints)
            throws KeyStoreException,
                   InvalidAlgorithmParameterException
Create a new PKIXBuilderParameters object, populating the trusted certificates set with all X.509 certificates found in the given key store. All certificates found in the key store are assumed to be trusted by this constructor.
Parameters:
keystore - The key store.
targetConstraints - The target certificate constraints.
Throws:
KeyStoreException - If the certificates cannot be retrieved from the key store.
InvalidAlgorithmParameterException - If there are no certificates in the key store.
NullPointerException - If keystore is null.

Method Details

getMaxPathLength

public int getMaxPathLength()
Returns the maximum length of certificate paths to build.

If this value is 0 it is taken to mean that the certificate path should contain only one certificate. A value of -1 means that the certificate path length is unconstrained. The default value is 5.

Returns:
The maximum path length.

setMaxPathLength

public void setMaxPathLength(int maxPathLength)
Sets the maximum length of certificate paths to build.
Parameters:
maxPathLength - The new path length.
Throws:
IllegalArgumentException - If maxPathLength is less than -1.

toString

public String toString()
Returns a printable representation of these parameters.
Overrides:
toString in interface PKIXParameters
Returns:
A printable representation of these parameters.
