Method Detail

createCore

public static Core createCore()

Creates the Core object for the application. There can only be one Core object per application. Uses CoreConfig.getAgencyId() to determine the agencyId. This means it typically uses the agency ID specified by the Java property -Dtransitime.core.agencyId .

The Core singleton, or null if could not create it

getInstance

public static Core getInstance()

For obtaining singleton Core object

getDbConfig

public DbConfig getDbConfig()

Makes the config data available to all

Returns:

getServiceUtils

public ServiceUtils getServiceUtils()

Returns the ServiceUtils object that can be reused for efficiency.

Returns:

getTime

public void setSystemTime(long systemEpochTime)

For setting the system time when in playback or batch mode.

Parameters:

systemTime -

getLogger

public static final org.slf4j.Logger getLogger()

Returns the Core logger so that each class doesn't need to create its own and have it be configured properly.
