!Const

The !Const tag is used to tie a port of a module to a constant value, rather than connecting it to another module. For more information on describing interconnectivity, see the !Connect and !Mod tag descriptions.

Note

In the future !Def and !Const tags may be merged into one new tag in order to reduce complexity of the schema.

Usage

The !Const tag is primitive, so it is preferable to use sequence rather than mapping syntax - although both are allowed:

- !Connect
  const:
  - !Point [a_port, child_block]
  - !Const [1]

- !Connect
  const:
  - !Point [b_port, child_block]
  - !Const
    value: 2

class blade.schema.ph_const.Const(value, name='unknown')

Defines a constant value tie for a port

__init__(value, name='unknown')

Initialisation of the !Const tag

Parameters

• name – Optional name for the value
