    Modifier and Type
    Method
    Description

    getCacheSizePerConnection()
    Returns the cache size for the current connection.
    int
    getMaxCacheSize()
    Returns the maximum size of the statement cache.
    boolean
    isCacheCallable()
    Checks if callable statements are being cached.
    boolean
    isCachePrepared()
    Checks if prepared statements are being cached.

  • Method Details

    • isCachePrepared

      boolean isCachePrepared()
      Checks if prepared statements are being cached.
      Returns:
      true if prepared statement caching is enabled

    • isCacheCallable

      boolean isCacheCallable()
      Checks if callable statements are being cached.
      Returns:
      true if callable statement caching is enabled

    • getMaxCacheSize

      int getMaxCacheSize()
      Returns the maximum size of the statement cache.
      Returns:
      maximum cache size

    • getCacheSize

      int getCacheSize()
      Returns the number of statements currently held in the statement cache, counted across all connections that belong to the same connection pool - the value the max limit is compared against. The number is a snapshot of the pool's accounting at the moment of the read; it is not a handle that can be used to change that accounting.
      Returns:
      the number of cached statements, or -1 if this interceptor instance is not bound to a pooled connection

    • getCacheSizePerConnection

      int getCacheSizePerConnection()
      Returns the cache size for the current connection.
      Returns:
      number of cached statements for this connection
