de.dentrassi.crypto.pem.AbstractReadOnlyKeyStore Maven / Gradle / Ivy
Go to download
This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including
all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and
JMS BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up
with different versions on classes on the class path).
The newest version!

/**
* An abstract implementation of {@link KeyStoreSpi}, implementing only mutating operations as "not supported".
* This idea behind this implementation, is to provide a base class which implements all operations, which would change
* the state of the key store, throwing an "unsupported operation". This allows sub-classes of this implementation to
* focus on implementing the "get" style methods only.
