- * @class MemoryMap
- *
- * Represents the contents of a memory layout, with main focus into (possibly sparse) blocks of data.
- *
- * A {@linkcode MemoryMap} acts as a subclass of
- * {@linkcode https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Map|Map}.
- * In every entry of it, the key is the starting address of a data block (an integer number),
- * and the value is the Uint8Array with the data for that block.
- *
- * The main rationale for this is that a .hex file can contain a single block of contiguous
- * data starting at memory address 0 (and it's the common case for simple .hex files),
- * but complex files with several non-contiguous data blocks are also possible, thus
- * the need for a data structure on top of the Uint8Arrays.
- *
- * In order to parse .hex files, use the {@linkcode MemoryMap.fromHex} static factory
- * method. In order to write .hex files, create a new {@linkcode MemoryMap} and call
- * its {@linkcode MemoryMap.asHexString} method.
- *
- * @extends Map
- * @example
- * import MemoryMap from 'nrf-intel-hex';
- *
- * let memMap1 = new MemoryMap();
- * let memMap2 = new MemoryMap([[0, new Uint8Array(1,2,3,4)]]);
- * let memMap3 = new MemoryMap({0: new Uint8Array(1,2,3,4)});
- * let memMap4 = new MemoryMap({0xCF0: new Uint8Array(1,2,3,4)});
