# Interface CertSelector

All Superinterfaces:
  `Cloneable`

All Known Implementing Classes:
  `X509CertSelector`

public interface CertSelector extends Cloneable
A selector that defines a set of criteria for selecting `Certificate`s. Classes that implement this interface are often used to specify which `Certificate`s should be retrieved from a `CertStore`.

Concurrent Access

Unless otherwise specified, the methods defined in this interface are not thread-safe. Multiple threads that need to access a single object concurrently should synchronize amongst themselves and provide the necessary locking. Multiple threads each manipulating separate objects need not synchronize.
