Values(ByRefValue)

Used by jsii to construct an instance of this class from a Javascript-owned object reference

protected Values(ByRefValue reference)

Parameters

reference Amazon.JSII.Runtime.Deputy.ByRefValue

The Javascript-owned object reference

Values(DeputyBase.DeputyProps)

Used by jsii to construct an instance of this class from DeputyProps

protected Values(DeputyBase.DeputyProps props)

Parameters

props Amazon.JSII.Runtime.Deputy.DeputyBase.DeputyProps

The deputy props

Methods

Attribute(String)

(experimental) Allows assigning a value to the specified attribute.

public static AttributeValuesStep Attribute(string attr)

Parameters

attr System.String

Returns

AttributeValuesStep

Remarks

Stability: Experimental

Projecting(String)

(experimental) Treats the specified object as a map of assignments, where the property names represent attribute names.

public static AttributeValues Projecting(string arg = null)

Parameters

arg System.String

Returns

AttributeValues

Remarks

It’s opinionated about how it represents some of the nested objects: e.g., it will use lists (“L”) rather than sets (“SS”, “NS”, “BS”). By default it projects the argument container ("$ctx.args").
