FlowPDF::Log

This class provides methods to support the logging functionality of FlowPDF. This class gets loaded by FlowPDF, before other components get initialized.

A few points to note about logging.
  • The log level which is retrieved from the debugLevel property in the configuration, control which messages get written to the logs.

  • + The Methods provided by this class facilitate the classification of a

    message into any one of the following.
    • Log

    • Debug

    • Trace

    • Warning

    • Error

  • The log level and the classification of messages work together to surface the severity of a message.

  • Regardless of the log level Warning and Error Messages will always be written.

  • Logged messages are appropriately prefaced by [DEBUG], [TRACE], [WARNING], [ERROR] based on their classification.

It supports the following log levels:

  • INFO

    This is the default level.

    debugLevel property should be set to 0.

  • DEBUG

    Provides the same output from INFO level + debug output.

    debugLevel property should be set to 1.

  • TRACE

    Provides the same output from DEBUG level + TRACE output.

    debugLevel property should be set to 2.
