Class SSLContextSpi

    java.lang.Object
      javax.net.ssl.SSLContextSpi

public abstract class SSLContextSpi
extends Object

This class defines the Service Provider Interface (SPI) for the `SSLContext` class.

All the abstract methods in this class must be implemented by each cryptographic service provider who wishes to supply the implementation of a particular SSL context.

Since:
  1.4

Method Summary
`protected abstract SSLSessionContext` | `engineGetClientSessionContext()` Returns a client `SSLSessionContext` object for this context.
`protected abstract SSLSessionContext` | `engineGetServerSessionContext()` Returns a server `SSLSessionContext` object for this context.
`protected abstract SSLServerSocketFactory` | `engineGetServerSocketFactory()` Returns a `ServerSocketFactory` object for this context.
`protected abstract SSLSocketFactory` | `engineGetSocketFactory()` Returns a `SocketFactory` object for this context.
`protected abstract void` | `engineInit(KeyManager[] km, TrustManager[] tm, SecureRandom sr)` Initializes this context.
