Method Detail

getTextFromFile

public static java.lang.String getTextFromFile(java.io.File file)

getTextFromStream

public static java.lang.String getTextFromStream(java.io.InputStream inputStream)

saveTextToFile

public static boolean saveTextToFile(java.io.File file,
                                     java.lang.String text)

unzip

public static java.lang.Exception unzip(java.io.InputStream inputStream,
                                        java.io.File unzipTo,
                                        java.lang.String[] filesToIgnore)

Parameters:

inputStream -

unzipTo -

filesToIgnore - files that should not be unzipped. Directories that should not be unzipped should end in "/", so it's clear that they are directories (otherwise, the files in them will be unzipped).

Returns:

unzip

public static java.lang.Exception unzip(java.io.InputStream inputStream,
                                        java.io.File unzipTo)

copyDir

public static void copyDir(java.io.File srcDir,
                           java.io.File dstDir,
                           boolean overwrite)
                    throws java.io.IOException

Utility method to copy one directory to another via NIO. If the destination directory doesn't exist, it will be created. Duplicate files in the destination directory will be overwritten if overwrite is true. The existing contents of the destination will not be deleted unless overwritten. NOTE: This method is not safe for directory structures containing cycles.

Parameters:

srcDir - the source directory

dstDir - the destination directory

overwrite - if true, duplicate files will be overwritten

Throws:

java.io.IOException

copyFile

public static void copyFile(java.io.File inputFile,
                            java.io.File outputFile,
                            boolean overwrite)
                     throws java.io.IOException

Throws:

java.io.IOException

deleteDir

public static boolean deleteDir(java.io.File dir)
                         throws java.io.IOException

Utility method to recursively delete an entire directory (a la "rm -rf").

Parameters:

dir - the directory to delete

Throws:

java.io.IOException - if there is any problem with file manipulation

java.lang.IllegalArgumentException - if dir is not a directory
