How do I get and set ag-grid state?

Question

How can I obtain and re-set the state of an ag-grid table? I mean, which columns are being show, in what order, with what sorting and filtering, etc.

Update: getColumnState and setColumnState seem to be close to what I want, but I cannot figure out the callbacks in which I should save and restore the state. I tried restoring it in onGridReady but when the actual rows are loaded, I lose the state.

There is a very specific example on their website providing details for what you are trying to do: javascript-grid-column-definitions

function saveState() {
    window.colState = gridOptions.columnApi.getColumnState();
    window.groupState = gridOptions.columnApi.getColumnGroupState();
    window.sortState = gridOptions.api.getSortModel();
    window.filterState = gridOptions.api.getFilterModel();
    console.log('column state saved');
}

and for restoring:

function restoreState() {
    gridOptions.columnApi.setColumnState(window.colState);
    gridOptions.columnApi.setColumnGroupState(window.groupState);
    gridOptions.api.setSortModel(window.sortState);
    gridOptions.api.setFilterModel(window.filterState);
    console.log('column state restored');
}
