NAME
EntityModel::Gather - asynchronous helper functions for EntityModel
VERSION
version 0.102
SYNOPSIS
use EntityModel::Gather;DESCRIPTION
Wrapper class for executing code once data values have been populated.
Given a set of data key => value pairs, this module will request population from each provider. Once all data values are available, the on_ready event is triggered, and the data values are passed to the provided handler. If it is impossible to retrieve data values for some reason, the on_error handler is called instead.
Each of the values passed must be one of the following:
Subclass of EntityModel::Pending - requests callback when data value has been populated
Subclass of EntityModel::EntityBase - requests callback when populated
Scalar value - this will be used as-is
undef - this will be used as-is
Any other value will cause the scalar handling to be used.
METHODS
new
Create a new instance. Takes a list of key, value pairs indicating which data values to wait for.
add_pending
Adds the given key and value to the pending list. If the value is immediately available (simple scalar, for example) then this will pass the value through immediately.
