andes.core.service.EventFlag

class andes.core.service.EventFlag(u, vtype: type | None = None, name: str | None = None, tex_name=None, info=None)

Service to flag events when the input value changes. The typical input is a v-provider with binary values.

Implemented by providing self.check(**kwargs) as v_numeric. EventFlag.v stores the values of the input variable in the most recent iteration/step.

After the evaluation of self.check(), self.v will be updated.

__init__(u, vtype: type | None = None, name: str | None = None, tex_name=None, info=None)
