MockStringContentFactory

public MockStringContentFactory()

Method Details

newMockInputStream

public static InputStream newMockInputStream(String contents)

Returns a new InputStream that gives access to the contents as given in the input string, encoded in UTF-8.

Parameters:

contents -

Returns:

an input stream for the given string

newMockInputStream

public static InputStream newMockInputStream(byte[] contents)

Returns a new InputStream that gives access to the contents as given in the input bytes.

Parameters:

contents -

Returns:

an input stream for the given bytes

getStringFromUrl

public static String getStringFromUrl(URL url)
                               throws IOException

Loads a string from the file at the given URL. This should only be used for relatively small files, obviously. The file contents is interpreted as UTF-8.

Parameters:

url -

Returns:

string contents of the file at the given URL

Throws:

IOException - if the URL could not be resolved or the file could not be read

getStringFromBufferedReader

public static String getStringFromBufferedReader(BufferedReader bufferedReader)
                                          throws IOException

Loads a string from the given buffered reader. Newline will be appended after each line but the last.

Parameters:

bufferedReader -

Returns:

string contents of the buffered reader

Throws:

IOException - if it was not possible to read from the buffered reader

getStringFromInputStream

public static String getStringFromInputStream(InputStream inputStream)
                                       throws IOException

Loads a string from the given input stream. UTF-8 encoding will be assumed. Newline will be appended after each line but the last.

Parameters:

inputStream -

Returns:

string contents of the input stream

Throws:

IOException - if it was not possible to read from the buffered reader

getFailingInputStream

public static InputStream getFailingInputStream()

Returns an input stream that will throw IOExceptions on common reading operations.

Returns:

input stream that fails on reading

getBytesFromString

public static byte[] getBytesFromString(String string,
 CompressionType compressionType)
                                 throws IOException

Turns a string into a sequence of bytes, possibly compressed. In any case, the character encoding used for converting the string into bytes is UTF8.

Parameters:

string -

compressionType -

Returns:

Throws:

IOException
