Property Collections and Logging APIs

This section describes classes for property collections and logging.

• Properties class. Provides a collection of properties, each of which is a key/value pair. Each key is a string, and the value can be a string or an integer.
• Log class. Defines methods available to clients that need to write a log message to their GemFire system shared log file. Any attempt to use an instance after its connection is disconnected throws a NotConnectedException. For any logged message the log file contains:
  • The log level of the message.
  • The time the message was logged.
  • The ID of the connection and thread that logged the message.
  • The message itself, possibly with an exception including its stack trace.
