Method Documentation
void append(ScaleRangeDisplayFilter scaleRangeDisplayFilter) |
Appends the scaleRangeDisplayFilter to the scale range display filter list model.
bool contains(ScaleRangeDisplayFilter scaleRangeDisplayFilter) |
Returns true if the list model contains the specified scaleRangeDisplayFilter.
Receives a callback function to execute for each scale range display filter in the model.
The callback function can take from 0 to 3 optional arguments, in order:
- element Current display filter.
- index Current index in array.
- array Reference to the ScaleRangeDisplayFilterListModel.
Returns undefined if no error occurred, and an error message otherwise.
const error = scaleRangeDisplayFilterListModel.forEach(function(element, index, array) { ... }); if (error) { console.error(error.message); }
Returns the scale range display filter at the specified index.
int indexOf(ScaleRangeDisplayFilter scaleRangeDisplayFilter) |
Returns the index of the scaleRangeDisplayFilter specified.
void insert(int index, ScaleRangeDisplayFilter scaleRangeDisplayFilter) |
Inserts a scaleRangeDisplayFilter at a specified index in the list model.
Moves one scale range display filter from an index in the list model to a different index.
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.
void removeOne(ScaleRangeDisplayFilter scaleRangeDisplayFilter) |
Removes the specified scaleRangeDisplayFilter from the list model.
