* @name File
|
|
* @description
|
|
* This plugin implements a File API allowing read/write access to files residing on the device.
|
|
*
|
|
* The File class implements static convenience functions to access files and directories.
|
|
*
|
|
* Example:
|
|
* ```
|
|
* import { File } from '@ionic-native/file';
|
|
*
|
|
* constructor(private file: File) { }
|
|
*
|
|
* ...
|
|
*
|
|
* this.file.checkDir(this.file.dataDirectory, 'mydir').then(_ => console.log('Directory exists')).catch(err => console.log('Directory doesnt exist'));
|
|
*
|
|
* ```
|
|
*
|
|
* This plugin is based on several specs, including : The HTML5 File API http: //www.w3.org/TR/FileAPI/
|
|
* The (now-defunct) Directories and System extensions Latest: http: //www.w3.org/TR/2012/WD-file-system-api-20120417/
|
|
* Although most of the plugin code was written when an earlier spec was current: http: //www.w3.org/TR/2011/WD-file-system-api-20110419/
|
|
* It also implements the FileWriter spec : http: //dev.w3.org/2009/dap/file-system/file-writer.html
|
|
* @interfaces
|
|
* IFile
|
|
* Entry
|
|
* DirectoryEntry
|
|
* DirectoryReader
|
|
* FileSystem
