Method Detail

serializeString

public static void serializeString(File file,
                                   String string)
                            throws IOException

Deprecated. To be removed in cocoon 2.3

Dump a String to a text file.

Parameters:

file - The output file

string - The string to be dumped

Throws:

IOException - IO Error

serializeString

public static void serializeString(File file,
                                   String string,
                                   String encoding)
                            throws IOException

Deprecated. To be removed in cocoon 2.3

Dump a String to a text file.

Parameters:

file - The output file

string - The string to be dumped

encoding - The encoding for the output file or null for default platform encoding

Throws:

IOException - IO Error

deserializeString

public static String deserializeString(File file)
                                throws IOException

Load a text file contents as a String. This method does not perform enconding conversions

Parameters:

file - The input file

Returns:

The file contents as a String

Throws:

IOException - IO Error

serializeObject

public static void serializeObject(File file,
                                   Object object)
                            throws IOException

Deprecated. To be removed in cocoon 2.3

This method serializes an object to an output stream.

Parameters:

file - The output file

object - The object to be serialized

Throws:

IOException - IOError

deserializeObject

public static Object deserializeObject(File file)
                                throws IOException,
                                       ClassNotFoundException

Deprecated. To be removed in cocoon 2.3

This method deserializes an object from an input stream.

Parameters:

file - The input file

Returns:

The deserialized object

Throws:

IOException - IOError

ClassNotFoundException

normalizedFilename

public static String normalizedFilename(String filename)

Return a modified filename suitable for replicating directory structures below the store's base directory. The following conversions are performed:

• Path separators are converted to regular directory names
• File path components are transliterated to make them valid (?) programming language identifiers. This transformation may well generate collisions for unusual filenames.

Returns:

The transformed filename

pathComponent

public static String pathComponent(String filename)

Deprecated. To be removed in cocoon 2.3

Remove file information from a filename returning only its path component

Parameters:

filename - The filename

Returns:

The path information

fileComponent

public static String fileComponent(String filename)

Deprecated. To be removed in cocoon 2.3

Remove path information from a filename returning only its file component

Parameters:

filename - The filename

Returns:

The filename sans path information

baseName

public static String baseName(String filename)

Deprecated. To be removed in cocoon 2.3

Strip a filename of its last extension (the portion immediately following the last dot character, if any)

Parameters:

filename - The filename

Returns:

The filename sans extension

getFullFilename

public static String getFullFilename(File file)

Get the complete filename corresponding to a (typically relative) File. This method accounts for the possibility of an error in getting the filename's canonical path, returning the io/error-safe absolute form instead

Parameters:

file - The file

Returns:

The file's absolute filename

getContextFilePath

public static String getContextFilePath(String directoryPath,
                                        String filePath)

Return the path within a base directory

createFile

public static File createFile(File destDir,
                              String filename)

Return a file with the given filename creating the necessary directories if not present.

Parameters:

filename - The file

Returns:

The created File instance

objectToBytes

public static byte[] objectToBytes(Object object)
                            throws IOException

Deprecated. To be removed in cocoon 2.3

Returns a byte array from the given object.

Parameters:

object - to convert

Returns:

byte array from the object

Throws:

IOException

bytesToObject

public static Object bytesToObject(byte[] bytes)
                            throws IOException,
                                   ClassNotFoundException

Deprecated. To be removed in cocoon 2.3

Returns a object from the given byte array.

Parameters:

bytes - array to convert

Returns:

object

Throws:

IOException

ClassNotFoundException
