                                       Core
Known Subclasses:

A definition of the "active" part of a service.

A core will receive input from a renderer in the form of a ``svcs.CoreArgs`` (see `Core Args`_). A core will return a table or perhaps directly data as discussed in `DaCHS' Service Interface`_ .

The abstract core element will never occur in resource descriptors. See `Cores Available`_ for concrete cores. Use the names of the concrete cores in RDs.

Properties

Inherited from object: __class__

Method Details

__init__(self, parent, **kwargs)
(Constructor)

source code 

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__
(inherited documentation)

__repr__(self)
(Representation operator)

source code 

repr(x)

Overrides: object.__repr__
(inherited documentation)

__str__(self)
(Informal representation operator)

source code 

str(x)

Overrides: object.__str__
(inherited documentation)

completeElement(self, ctx)

source code 
Overrides: base.structure.Structure.completeElement

initialize(self)

source code 

override to configure the custom core before use.

This is typically where you pull input or output tables from the RD in customCores. Actual DaCHS code should use completeElement as usual.
