Constructs and prepares an instance of this scheduler.
The type of statistics to be saved to the database.
Should be defaulted to "user".
The arguments passed to the command. Typically, this holds required parameters of commands.
The internal dApp configuration object. This object is used to configure key functionalities such as the name of a dApp and the enabled scopes of the backend runtime.
Memory store for the last time of execution. This is used in getStateData to update the latest execution state.
The internal dApp network configuration object. This object is used to configure the access to the underlying blockchain network.
The period format i.e. "D", "W" or "M".
This field will be overriden by sub-classes during initialization.
The command scope. This is the scope that must be enabled
through the configuration files for this command to be
available.
This property is required through the extension of
BaseCommand.
Requires state information of the module. This object is typically populated upon first execution and updated any time later.
This method must return a command name. Note that
it should use only characters of: A-Za-z0-9:-_.
e.g. "scope:name"
This property is required through the extension of
StatisticsCommand.
This method must return a command signature that
contains hints on the command name and its required
and optional arguments.
e.g. "command
This property is required through the extension of
StatisticsCommand.
Getter for the discovery state identifier, e.g.
"discovery.accounts", "discovery.transactions",
"payout.outputs" etc.
This method is an implementation necessary because
of the extensions of StatefulModule.
This method implements the statistics logic for this command that will aggregate relevant users.
Method to create aggregation query to calculate statistics information
based on config's collection and fields values.
This method uses the logger to print debug messages.
This method uses the logger to print error messages.
Optionally, a stack can be passed to print a stack trace.
Method to generate period string representation of today's search range.
The result string is in format: {year}{month}{day}.
The current {@link Date} instance that is passed from LeaderboardAggregation.
The period string representation of today's search range.
Creates a state query for this discovery service. Each discovery service shall set its own stateIdentifier which is considered the identifier of the discovery module's state document.
This method uses the logger to print info messages.
This helper method serves as a parser for the -c
or --collection option of this command.
The statistics collection can contain a mongo collection
name that must exist in the database.
The --collection argument as passed in the terminal.
A validated mongo database collection name.
This method is the entry point of any command line
executed command. nest-commander implements a flow
where this method is called with parameters that are
respectively the raw arguments and the parsed arguments
to this command call.
This method uses the stateService to fetch the
current execution and also uses it to update the state.
Note that the runWithOptions method is called inside
a try-catch block to force the error handling process.
This method is the entry point of this scheduler. Due to
the usage of the Cron decorator, and the implementation
the nest backend runtime is able to discover this when the
processor scope is enabled.
This method is necessary to make sure this command is run
with the correct --collection option.
This scheduler is registered to run every ten minutes.
Note that a manual execution is also triggered such that
this aggregation runs directly upon nestjs registration of
the scheduler.
This method implements the execution logic for
statistics commands that extend this class. Child
classes must implement a aggregate method
that is called in here.
Note that this method is called by BaseCommand
under the hood, which permits to execute and track
failures more consistently at a higher level.
The parsed runtime arguments passed to the command.
This method prints usage information to the command line
and is used by nest-commander to print a correctly formatted
help message.
Note that usage methods can be overwritten but must always
print a standard command line signature.
Generated using TypeDoc
The implementation for user statistics aggregation scheduler. Contains source code for the execution logic of a command with name:
Statistics:UserAggregation.current aggregation does not use dates to filter relevant data
the implementation should make use of previous aggregation too
