CertPathValidatorSpi

public abstract class CertPathValidatorSpi
extends Object

java.lang.Object
↳	java.security.cert.CertPathValidatorSpi

The Service Provider Interface (SPI) for the CertPathValidator class. All CertPathValidator implementations must include a class (the SPI class) that extends this class (CertPathValidatorSpi) and implements all of its methods. In general, instances of this class should only be accessed through the CertPathValidator class. For details, see the Java Cryptography Architecture.

Concurrent Access

Instances of this class need not be protected against concurrent access from multiple threads. Threads that need to access a single CertPathValidatorSpi instance concurrently should synchronize amongst themselves and provide the necessary locking before calling the wrapping CertPathValidator object.

However, implementations of CertPathValidatorSpi may still encounter concurrency issues, since multiple threads each manipulating a different CertPathValidatorSpi instance need not synchronize.

Summary

Public constructors
`CertPathValidatorSpi()` The default constructor.

Public methods
`CertPathChecker`	`engineGetRevocationChecker()` Returns a `CertPathChecker` that this implementation uses to check the revocation status of certificates.
`abstract CertPathValidatorResult`	`engineValidate(CertPath certPath, CertPathParameters params)` Validates the specified certification path using the specified algorithm parameter set.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

CertPathValidatorSpi

Added in API level 1

public CertPathValidatorSpi ()

The default constructor.

Public methods

engineGetRevocationChecker

Added in API level 24

public CertPathChecker engineGetRevocationChecker ()

Returns a CertPathChecker that this implementation uses to check the revocation status of certificates. A PKIX implementation returns objects of type PKIXRevocationChecker.

The primary purpose of this method is to allow callers to specify additional input parameters and options specific to revocation checking. See the class description of CertPathValidator for an example.

This method was added to version 1.8 of the Java Platform Standard Edition. In order to maintain backwards compatibility with existing service providers, this method cannot be abstract and by default throws an UnsupportedOperationException.

Returns
`CertPathChecker`	a `CertPathChecker` that this implementation uses to check the revocation status of certificates

Throws
`UnsupportedOperationException`	if this method is not supported

engineValidate

Added in API level 1

public abstract CertPathValidatorResult engineValidate (CertPath certPath, 
                CertPathParameters params)

Validates the specified certification path using the specified algorithm parameter set.

The CertPath specified must be of a type that is supported by the validation algorithm, otherwise an InvalidAlgorithmParameterException will be thrown. For example, a CertPathValidator that implements the PKIX algorithm validates CertPath objects of type X.509.

Parameters
`certPath`	`CertPath`: the `CertPath` to be validated
`params`	`CertPathParameters`: the algorithm parameters

Returns
`CertPathValidatorResult`	the result of the validation algorithm

Throws
`CertPathValidatorException`	if the `CertPath` does not validate
`InvalidAlgorithmParameterException`	if the specified parameters or the type of the specified `CertPath` are inappropriate for this `CertPathValidator`
