HudsonPlots This library provides functions to assist with hudson plots in mXrap

Some functions for dealing with IJOC definitions of grid data.

This library provides k-d tree functionality for searching tables. The dimensions of the k-d trees are table columns. The k-d tree can then be searched based on those dimensions. Compared to the built-in k-d tree, the search functions provided by this k-d tree require the caller to provide a function that determines the distances between two points in the k-dimensional space. That is, you provide the definition of distance when performing searches such as findNearestNeighbour or findAtLeastXWithinRange.

Typed Array Extensions'mxjs/base/utilities/typed_array_extensions.js');

Adds convenience methods to the TypedArray types.

Wrap TypedArray objects to provide functions that rely on dynamic sizing (push, pop, etc.).
Xadapter This library provides adapters for use with different data inputs and outputs.

Adapters are objects that behave like data tables, while reading from or writing to a different underlying data structure, such as an array or a set of arrays.

Tabular data can be stored in different ways within mXrap, e.g. in a data table, or in a set of arrays, or in an interleaved array. As a result, it can be difficult to standardise what each library function should accept as input. After much consideration, the mXrap team have settled on the data table method - libraries in mXrap will in general take in a Table and its read or write functions as the standard way of reading/writing tabular data.

If your tabular data is in a set of column arrays, or in an interleaved array, you will instead want to use an adapter. You can create an adapter over the arrays/array, which provides you with an object that pretends to be a data table, when its actually reading from/writing to the underlying arrays. You can then use this adapter to provide input/output to library functions which take in data tables.

Adapters can be read-only, or write-enabled. You can use standard data table methods like size() and if write-enabled, grow(), resize(), reserve().

You can also create adapters that are in "subset" mode, that is, they operate over a specified range of the arrays or data table. When in "subset" mode, you can write to the records (if write-enabled), but you cannot resize or add/remove records.

One caveat with using adapters is that they are relatively expensive to create. Hence you should always free() your adapters once you are done using them. Freed adapters are re-used where possible, which greatly reduces the overhead of using adapters.
