private static final String	PROPERTYNAME
private static final String	DEFAULTPROPERTY
private final Provider	provider
private CertPathBuilderSpi	spiImpl
private final String	algorithm

Constructors Summary
protected CertPathBuilder(CertPathBuilderSpi builderSpi, Provider provider, String algorithm) Creates a new {@code CertPathBuilder}. param builderSpi the implementation delegate. param provider the provider. param algorithm the desired algorithm available at the provider. since Android 1.0 this.provider = provider; this.algorithm = algorithm; this.spiImpl = builderSpi;

Methods Summary
public final java.security.cert.CertPathBuilderResult	build(java.security.cert.CertPathParameters params) Builds a certification path with the specified algorithm parameters. param params the algorithm parameters. return the built certification path. throws CertPathBuilderException if the build fails. throws InvalidAlgorithmParameterException if the specified parameters cannot be used to build with this builder. see CertPathBuilderResult since Android 1.0 return spiImpl.engineBuild(params);
public final java.lang.String	getAlgorithm() Returns the algorithm name of this instance. return the algorithm name of this instance. since Android 1.0 return algorithm;
public static final java.lang.String	getDefaultType() Returns the default {@code CertPathBuilder} type from the Security Properties. return the default {@code CertPathBuilder} 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.CertPathBuilder	getInstance(java.lang.String algorithm) Creates a new {@code CertPathBuilder} instance with the specified algorithm. param algorithm the name of the algorithm. return a builder for the requested algorithm. throws NullPointerException if the algorithm is {@code null}. throws NoSuchAlgorithmException if no installed provider can provide the algorithm. 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 CertPathBuilder((CertPathBuilderSpi) engine.spi, engine.provider, algorithm); }
public static java.security.cert.CertPathBuilder	getInstance(java.lang.String algorithm, java.lang.String provider) Creates a new {@code CertPathBuilder} instance from the specified provider providing the specified algorithm. param algorithm the name of the algorithm. param provider the name of the provider. return a builder for the requested algorithm. throws NoSuchAlgorithmException if the specified provider cannot provide the 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.CertPathBuilder	getInstance(java.lang.String algorithm, java.security.Provider provider) Creates a new {@code CertPathBuilder} instance from the specified provider providing the specified algorithm. param algorithm the name of the algorithm. param provider the provider. return a builder for the requested algorithm throws NoSuchAlgorithmException if the specified provider cannot provide the 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 CertPathBuilder((CertPathBuilderSpi) engine.spi, provider, algorithm); }
public final java.security.Provider	getProvider() Returns the provider of this instance. return the provider of this instance. since Android 1.0 return provider;
