Class IndexBuilder

Namespace

Bonsai.Expressions

Assembly

Bonsai.Core.dll

Represents an expression builder that applies an index operator to the elements of an observable sequence.

Note

If the operator is applied to a sequence of single values, a workflow property will be inferred based on compatible operator overloads and exposed in the property grid. The value of this property will be used as the argument when applying the operator to the elements in the source sequence.

If the operator is applied to a sequence of pairs of values, the second element in the pair is considered to be the argument to the operator.
