Imports
java.security.InvalidAlgorithmParameterException, java.util.Collection
The Service Provider Interface (SPI) for the CertStore class. All CertStore implementations must include a class (the SPI class) that extends this class (CertStoreSpi), provides a constructor with a single argument of type CertStoreParameters, and implements all of its methods. In general, instances of this class should only be accessed through the CertStore class. For details, see the Java Cryptography Architecture.

Concurrent Access

The public methods of all CertStoreSpi objects must be thread-safe. That is, multiple threads may concurrently invoke these methods on a single CertStoreSpi object (or more than one) with no ill effects. This allows a CertPathBuilder to search for a CRL while simultaneously searching for further certificates, for instance.

Simple CertStoreSpi implementations will probably ensure thread safety by adding a synchronized keyword to their engineGetCertificates and engineGetCRLs methods. More sophisticated ones may allow truly concurrent access.

Method Detail

engineGetCertificatesback to summary
public abstract Collection<? extends Certificate> engineGetCertificates(CertSelector selector) throws CertStoreException

Returns a Collection of Certificates that match the specified selector. If no Certificates match the selector, an empty Collection will be returned.

For some CertStore types, the resulting Collection may not contain all of the Certificates that match the selector. For instance, an LDAP CertStore may not search all entries in the directory. Instead, it may just search entries that are likely to contain the Certificates it is looking for.

Some CertStore implementations (especially LDAP CertStores) may throw a CertStoreException unless a non-null CertSelector is provided that includes specific criteria that can be used to find the certificates. Issuer and/or subject names are especially useful criteria.

Parameters
selector:CertSelector

A CertSelector used to select which Certificates should be returned. Specify null to return all Certificates (if supported).

Returns:Collection<? extends Certificate>

A Collection of Certificates that match the specified selector (never null)

Exceptions

engineGetCRLsback to summary
public abstract Collection<? extends CRL> engineGetCRLs(CRLSelector selector) throws CertStoreException

Returns a Collection of CRLs that match the specified selector. If no CRLs match the selector, an empty Collection will be returned.

For some CertStore types, the resulting Collection may not contain all of the CRLs that match the selector. For instance, an LDAP CertStore may not search all entries in the directory. Instead, it may just search entries that are likely to contain the CRLs it is looking for.

Some CertStore implementations (especially LDAP CertStores) may throw a CertStoreException unless a non-null CRLSelector is provided that includes specific criteria that can be used to find the CRLs. Issuer names and/or the certificate to be checked are especially useful.

Parameters
selector:CRLSelector

A CRLSelector used to select which CRLs should be returned. Specify null to return all CRLs (if supported).

Returns:Collection<? extends CRL>

A Collection of CRLs that match the specified selector (never null)
