    String algorithm) 
{
        this.factorySpi = factorySpi;
        this.provider = provider;
        this.algorithm = algorithm;
}

Creates a TrustManagerFactory object.

Parameters:

factorySpi - the delegate

provider - the provider

algorithm - the algorithm

 public final String getAlgorithm() 
{
        return this.algorithm;
}

Returns the algorithm name of this TrustManagerFactory object.

This is the same name that was specified in one of the getInstance calls that created this TrustManagerFactory object.

 public static final String getDefaultAlgorithm() 
{
        String type;
        type = AccessController.doPrivileged(new PrivilegedAction< String >() {
            public String run() {
                return Security.getProperty(
                    "ssl.TrustManagerFactory.algorithm");
            }
        });
        if (type == null) {
            type = "SunX509";
        }
        return type;
}

Obtains the default TrustManagerFactory algorithm name.

The default TrustManager can be changed at runtime by setting the value of the "ssl.TrustManagerFactory.algorithm" security property (set in the Java security properties file or by calling java.security.Security#setProperty(String, String) ) to the desired algorithm name.

 public static final TrustManagerFactory getInstance(String algorithm) throws NoSuchAlgorithmException 
{
        GetInstance.Instance instance = GetInstance.getInstance
                ("TrustManagerFactory", TrustManagerFactorySpi.class,
                algorithm);
        return new TrustManagerFactory((TrustManagerFactorySpi)instance.impl,
                instance.provider, algorithm);
}

Returns a TrustManagerFactory object that acts as a factory for trust managers.

This method traverses the list of registered security Providers, starting with the most preferred Provider. A new TrustManagerFactory object encapsulating the TrustManagerFactorySpi implementation from the first Provider that supports the specified algorithm is returned.

Note that the list of registered providers may be retrieved via the Security.getProviders() method.

 public static final TrustManagerFactory getInstance(String algorithm,
    String provider) throws NoSuchAlgorithmException, NoSuchProviderException 
{
        GetInstance.Instance instance = GetInstance.getInstance
                ("TrustManagerFactory", TrustManagerFactorySpi.class,
                algorithm, provider);
        return new TrustManagerFactory((TrustManagerFactorySpi)instance.impl,
                instance.provider, algorithm);
}

Returns a TrustManagerFactory object that acts as a factory for trust managers.

A new KeyManagerFactory object encapsulating the KeyManagerFactorySpi implementation from the specified provider is returned. The specified provider must be registered in the security provider list.

Note that the list of registered providers may be retrieved via the Security.getProviders() method.

 public static final TrustManagerFactory getInstance(String algorithm,
    Provider provider) throws NoSuchAlgorithmException 
{
        GetInstance.Instance instance = GetInstance.getInstance
                ("TrustManagerFactory", TrustManagerFactorySpi.class,
                algorithm, provider);
        return new TrustManagerFactory((TrustManagerFactorySpi)instance.impl,
                instance.provider, algorithm);
}

Returns a TrustManagerFactory object that acts as a factory for trust managers.

A new TrustManagerFactory object encapsulating the TrustManagerFactorySpi implementation from the specified Provider object is returned. Note that the specified Provider object does not have to be registered in the provider list.

 public final Provider getProvider() 
{
        return this.provider;
}

Returns the provider of this TrustManagerFactory object.

 public final TrustManager[] getTrustManagers() 
{
        return factorySpi.engineGetTrustManagers();
}

Returns one trust manager for each type of trust material.

 public final  void init(KeyStore ks) throws KeyStoreException 
{
        factorySpi.engineInit(ks);
}

Initializes this factory with a source of certificate authorities and related trust material.

The provider typically uses a KeyStore as a basis for making trust decisions.

For more flexible initialization, please see #init(ManagerFactoryParameters) .

 public final  void init(ManagerFactoryParameters spec) throws InvalidAlgorithmParameterException 
{
        factorySpi.engineInit(spec);
}

Initializes this factory with a source of provider-specific trust material.

In some cases, initialization parameters other than a keystore may be needed by a provider. Users of that particular provider are expected to pass an implementation of the appropriate ManagerFactoryParameters as defined by the provider. The provider can then call the specified methods in the ManagerFactoryParameters implementation to obtain the needed information.
