    Method Documentation

    void append(Analysis analysis)

    Appends an analysis to the analysis list model.

    void clear()

    Removes all analyses from the list model.

    bool contains(Analysis analysis)

    Returns true if the list model contains the specified analysis.

    error forEach(callback)

    Receives a callback function to execute for each analysis in the model.

    The callback function can take 0 to 3 optional arguments, in order:

    • element Current analysis.
    • index Current index in array.
    • array Reference to AnalysisListModel.

    Returns undefined if no error occurred, and an error message otherwise.

    const error = analysisListModel.forEach(function(element, index, array) {
    if (error) {

    Analysis get(int index)

    Returns the Analysis at the specified index.

    int indexOf(Analysis analysis)

    Returns the index of the analysis specified.

    void insert(int index, Analysis analysis)

    Inserts an analysis at a specified index in the list.

    void move(int from, int to)

    Moves one analysis from an index in the list model to a different index.

    void remove(int index, int count = 1)

    Removes one or more objects starting at the specified index.

    • index Index of first object to remove.
    • count Number of objects to remove. This parameter defaults to 1.

    No analysis will be removed if the specified index is out of range.

    [since Esri::ArcGISRuntime 100.5.] void removeOne(Analysis analysis)
