DescribeChildrenAsync ( this session, string environmentExpression, string expression, REvaluationResultProperties properties, string repr, int maxCount = null, |
Computes the children of the object represented by the given expression, and returns a collection of evaluation objects describing each child. See RSessionExtensions.TryEvaluateAndDescribeAsync for the meaning of other parameters. The resulting collection has an item for every child. If the child could be retrieved, and represents a value, the corresponding item is an IRValueInfo instance. If the child represents a promise, the promise is not forced, and the item is an IRPromiseInfo instance. If the child represents an active binding, the binding may be evaluated to retrieve the value, and the item is an IRActiveBindingInfo instance. If the child could not be retrieved, the item is an IRErrorInfo instance describing the error that prevented its retrieval. Where order matters (e.g. for children of atomic vectors and lists), children are returned in that order. Otherwise, the order is undefined. If an object has both ordered and unordered children (e.g. it is a vector with slots), then it is guaranteed that each group is reported as a contiguous sequence within the returned collection, and order is honored within each group; but groups themselves are not ordered relative to each other. |
