/**
|
|
* A <code>CertStore</code> that retrieves <code>Certificates</code> and
|
|
* <code>CRL</code>s from a <code>Collection</code>.
|
|
* <p>
|
|
* Before calling the {@link #engineGetCertificates engineGetCertificates} or
|
|
* {@link #engineGetCRLs engineGetCRLs} methods, the
|
|
* {@link #CollectionCertStore(CertStoreParameters)
|
|
* CollectionCertStore(CertStoreParameters)} constructor is called to
|
|
* create the <code>CertStore</code> and establish the
|
|
* <code>Collection</code> from which <code>Certificate</code>s and
|
|
* <code>CRL</code>s will be retrieved. If the specified
|
|
* <code>Collection</code> contains an object that is not a
|
|
* <code>Certificate</code> or <code>CRL</code>, that object will be
|
|
* ignored.
|
|
* <p>
|
|
* <b>Concurrent Access</b>
|
|
* <p>
|
|
* As described in the javadoc for <code>CertStoreSpi</code>, the
|
|
* <code>engineGetCertificates</code> and <code>engineGetCRLs</code> methods
|
|
* must be thread-safe. That is, multiple threads may concurrently
|
|
* invoke these methods on a single <code>CollectionCertStore</code>
|
|
* object (or more than one) with no ill effects.
|
|
* <p>
|
|
* This is achieved by requiring that the <code>Collection</code> passed to
|
|
* the {@link #CollectionCertStore(CertStoreParameters)
|
|
* CollectionCertStore(CertStoreParameters)} constructor (via the
|
|
* <code>CollectionCertStoreParameters</code> object) must have fail-fast
|
|
* iterators. Simultaneous modifications to the <code>Collection</code> can thus be
|
|
* detected and certificate or CRL retrieval can be retried. The fact that
|
|
* <code>Certificate</code>s and <code>CRL</code>s must be thread-safe is also
|
|
* essential.
