    • isCleared

      public final boolean isCleared()
      Description copied from interface: Credential
      Determines whether the credential value has been securely cleared.

      Returns:
      true if the credential has been cleared, otherwise false.
    • setCleared

      protected final void setCleared()

    • clear

      public final void clear()
      Description copied from interface: Credential
      Clears the credential. For example, if the credential includes a password, this method would overwrite the password value.
      Specified by:
      clear in interface Credential
    • clearCredential

      protected abstract void clearCredential()
      Invokes the specific subclass to securely clear the credential value. Some Credential subclasses contain credential values which are inherently secure, such as tokens, for which clearing the credential may not be necessary.

      For example, if the credential includes a password, this method would overwrite the password value.
