| Method Summary | |
| public static Object | deserializeFromByteArray(byte[] in)
Utility method to deserialize Object from byte[]. | | public static Object | deserializeFromFile(File file)
Utility method to deserialize an Object from given File. | | public static float | encodingMaxBytesPerChar(String encoding)
Return the maximum number of bytes per character in the named
encoding, or 0 if encoding is invalid or unsupported. | | public static File | ensureWriteableDirectory(String dir)
Ensure writeable directory.
If doesn't exist, we attempt creation.
Parameters:
dir - Directory to test for exitence and is writeable. | | public static List | ensureWriteableDirectory(List<File> dirs)
Ensure writeable directories.
If doesn't exist, we attempt creation.
Parameters:
dirs - List of Files to test. | | public static File | ensureWriteableDirectory(File dir)
Ensure writeable directory.
If doesn't exist, we attempt creation.
Parameters:
dir - Directory to test for exitence and is writeable. | | public static String | getClasspathPath(File file)
Parameters:
file - File to operate on. | | public static void | readFully(InputStream input, byte[] buf)
| | public static String | readFullyAsString(InputStream inputStream)
Read the entire stream to EOF, returning what's read as a String. | | public static void | readFullyToFile(InputStream is, File toFile)
Read the entire stream to EOF into the passed file. | | public static long | readFullyToFile(InputStream is, File toFile, byte[] buffer)
Read the entire stream to EOF into the passed file.
Closes is when done or if an exception.
Parameters:
is - Stream to read.
Parameters:
toFile - File to read into .
Parameters:
buffer - Buffer to use reading. | | public static byte[] | serializeToByteArray(Object object)
Utility method to serialize Object to byte[]. | | public static void | serializeToFile(Object object, File file)
Utility method to serialize an object to the given File. | | public static IOException | wrapAsIOException(Throwable e)
|
| deserializeFromByteArray | | public static Object deserializeFromByteArray(byte[] in)(Code) | | Utility method to deserialize Object from byte[].
Parameters:
in - byte[] source Object deserialized |
| deserializeFromFile | | public static Object deserializeFromFile(File file) throws IOException(Code) | | Utility method to deserialize an Object from given File.
Parameters:
file - File source deserialized Object
throws:
IOException - |
| encodingMaxBytesPerChar | | public static float encodingMaxBytesPerChar(String encoding)(Code) | | Return the maximum number of bytes per character in the named
encoding, or 0 if encoding is invalid or unsupported.
Parameters:
encoding - Encoding to consider. For now, should be java canonical name for the encoding. True if multibyte encoding. |
| ensureWriteableDirectory | | public static File ensureWriteableDirectory(String dir) throws IOException(Code) | | Ensure writeable directory.
If doesn't exist, we attempt creation.
Parameters:
dir - Directory to test for exitence and is writeable. The passed dir.
exception:
IOException - If passed directory does not exist and is notcreateable, or directory is not writeable or is not a directory. |
| ensureWriteableDirectory | | public static List ensureWriteableDirectory(List<File> dirs) throws IOException(Code) | | Ensure writeable directories.
If doesn't exist, we attempt creation.
Parameters:
dirs - List of Files to test. The passed dirs.
exception:
IOException - If passed directory does not exist and is notcreateable, or directory is not writeable or is not a directory. |
| ensureWriteableDirectory | | public static File ensureWriteableDirectory(File dir) throws IOException(Code) | | Ensure writeable directory.
If doesn't exist, we attempt creation.
Parameters:
dir - Directory to test for exitence and is writeable. The passed dir.
exception:
IOException - If passed directory does not exist and is notcreateable, or directory is not writeable or is not a directory. |
| getClasspathPath | | public static String getClasspathPath(File file)(Code) | |
Parameters:
file - File to operate on. Path suitable for use getting resources off the CLASSPATH(CLASSPATH resources always use '/' as path separator, even onwindows). |
| readFullyAsString | | public static String readFullyAsString(InputStream inputStream) throws IOException(Code) | | Read the entire stream to EOF, returning what's read as a String.
Parameters:
inputStream - String of the whole inputStream's contents
throws:
IOException - |
| readFullyToFile | | public static long readFullyToFile(InputStream is, File toFile, byte[] buffer) throws IOException(Code) | | Read the entire stream to EOF into the passed file.
Closes is when done or if an exception.
Parameters:
is - Stream to read.
Parameters:
toFile - File to read into .
Parameters:
buffer - Buffer to use reading. Count of bytes read.
throws:
IOException - |
| serializeToByteArray | | public static byte[] serializeToByteArray(Object object)(Code) | | Utility method to serialize Object to byte[].
Parameters:
object - Object to be serialized byte[] serialized form |
| serializeToFile | | public static void serializeToFile(Object object, File file) throws IOException(Code) | | Utility method to serialize an object to the given File.
Parameters:
object - Object to serialize
Parameters:
file - File to receive serialized copy
throws:
IOException - |
| wrapAsIOException | | public static IOException wrapAsIOException(Throwable e)(Code) | | Wrap generic Throwable as a checked IOException
Parameters:
e - wrapped exception IOException |
