Class PropertySource

Namespace

Bonsai.Expressions

Assembly

Bonsai.Core.dll

Represents a data source compatible with the specified workflow element property.

Property sources expose a value which can be set from the property grid and also generate an observable sequence that emits a notification whenever the property value changes, starting with the initial property value.

Tip

Property sources are commonly used to create new configuration parameters with custom names for nested workflows. To expose and rename a property source, use Property Mapping to externalize the property value and set its DisplayName.
