class
CertStoreSpi
extends Object
java.lang.Object | |
↳ | java.security.cert.CertStoreSpi |
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.

Collection<? extends CRL> engineGetCRLs (CRLSelector selector)
Returns a Collection
of CRL
s that
match the specified selector. If no CRL
s
match the selector, an empty Collection
will be returned.
For some CertStore
types, the resulting
Collection
may not contain all of the
CRL
s 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 CRL
s it is looking for.
Some CertStore
implementations (especially LDAP
CertStore
s) 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
CRL s should be returned. Specify null
to return all CRL s (if supported). |
Returns | |
---|---|
Collection<? extends CRL> |
A Collection of CRL s that
match the specified selector (never null ) |
Throws | |
---|---|
CertStoreException |
if an exception occurs |
Collection<? extends Certificate> engineGetCertificates (CertSelector selector)
Returns a Collection
of Certificate
s that
match the specified selector. If no Certificate
s
match the selector, an empty Collection
will be returned.
For some CertStore
types, the resulting
Collection
may not contain all of the
Certificate
s 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 Certificate
s it is looking for.
Some CertStore
implementations (especially LDAP
CertStore
s) 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.
