## 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.

    1.4
