Constructors Summary
protected CertPathValidator(CertPathValidatorSpi validatorSpi, Provider provider, String algorithm) Creates a new {@code CertPathValidator} instance. param validatorSpi the implementation delegate. param provider the security provider. param algorithm the name of the algorithm. since Android 1.0 this.provider = provider; this.algorithm = algorithm; this.spiImpl = validatorSpi;

Methods Summary
public final java.lang.String	getAlgorithm() Returns the certification path algorithm name. return the certification path algorithm name. since Android 1.0 return algorithm;
public static final java.lang.String	getDefaultType() Returns the default {@code CertPathValidator} type from the Security Properties. return the default {@code CertPathValidator} type from the Security Properties, or the string {@code "PKIX"} if it cannot be determined. since Android 1.0 String defaultType = AccessController .doPrivileged(new java.security.PrivilegedAction<String>() { public String run() { return Security.getProperty(PROPERTYNAME); } }); return (defaultType != null ? defaultType : DEFAULTPROPERTY);
public static java.security.cert.CertPathValidator	getInstance(java.lang.String algorithm) Returns a new certification path validator for the specified algorithm. param algorithm the algorithm name. return a certification path validator for the requested algorithm. throws NoSuchAlgorithmException if no installed provider provides the specified algorithm. throws NullPointerException if algorithm is {@code null}. since Android 1.0 if (algorithm == null) { throw new NullPointerException(Messages.getString("security.01")); //$NON-NLS-1$ } synchronized (engine) { engine.getInstance(algorithm, null); return new CertPathValidator((CertPathValidatorSpi) engine.spi, engine.provider, algorithm); }
public static java.security.cert.CertPathValidator	getInstance(java.lang.String algorithm, java.lang.String provider) Returns a new certification path validator for the specified algorithm from the specified provider. param algorithm the algorithm name. param provider the security provider name. return a certification path validator for the requested algorithm. throws NoSuchAlgorithmException if the specified security provider cannot provide the requested algorithm. throws NoSuchProviderException if no provider with the specified name can be found. throws NullPointerException if algorithm is {@code null}. throws IllegalArgumentException if provider is {@code null} or empty. since Android 1.0 if ((provider == null) || (provider.length() == 0)) { throw new IllegalArgumentException(Messages.getString("security.02")); //$NON-NLS-1$ } Provider impProvider = Security.getProvider(provider); if (impProvider == null) { throw new NoSuchProviderException(provider); } return getInstance(algorithm, impProvider);
public static java.security.cert.CertPathValidator	getInstance(java.lang.String algorithm, java.security.Provider provider) Returns a new certification path validator for the specified algorithm from the specified provider. param algorithm the algorithm name. param provider the security provider name. return a certification path validator for the requested algorithm. throws NoSuchAlgorithmException if the specified provider cannot provide the requested algorithm. throws IllegalArgumentException if provider is {@code null}. throws NullPointerException if algorithm is {@code null}. since Android 1.0 if (provider == null) { throw new IllegalArgumentException(Messages.getString("security.04")); //$NON-NLS-1$ } if (algorithm == null) { throw new NullPointerException(Messages.getString("security.01")); //$NON-NLS-1$ } synchronized (engine) { engine.getInstance(algorithm, provider, null); return new CertPathValidator((CertPathValidatorSpi) engine.spi, provider, algorithm); }
public final java.security.Provider	getProvider() Returns the security provider. return the provider. since Android 1.0 return provider;
public final java.security.cert.CertPathValidatorResult	validate(java.security.cert.CertPath certPath, java.security.cert.CertPathParameters params) Validates the {@code CertPath} with the algorithm of this {@code CertPathValidator} using the specified algorithm parameters. param certPath the certification path to be validated. param params the certification path validator algorithm parameters. return the validation result. throws CertPathValidatorException if the validation fails, or the algorithm of the specified certification path cannot be validated using the algorithm of this instance. throws InvalidAlgorithmParameterException if the specified algorithm parameters cannot be used with this algorithm. see CertPathValidatorResult since Android 1.0 return spiImpl.engineValidate(certPath, params);
