read

public LanguageProfile read(File profileFile)
                     throws IOException

Reads a LanguageProfile from a File in UTF-8.

Throws:

IOException

public LanguageProfile read(InputStream inputStream)
                     throws IOException

Reads a LanguageProfile from an InputStream in UTF-8.

Throws:

IOException

public List<LanguageProfile> read(ClassLoader classLoader,
 String profileDirectory,
 Collection<String> profileFileNames)
                           throws IOException

Load profiles from the classpath in a specific directory.

This is usually used to load built-in profiles, shipped with the jar.

Parameters:

classLoader - the ClassLoader to load the profiles from. Use MyClass.class.getClassLoader()

profileDirectory - profile directory path inside the classpath. The default profiles are in "languages".

profileFileNames - for example ["en", "fr", "de"].

Throws:

IOException

makePathForClassLoader

private String makePathForClassLoader(String profileDirectory,
 String fileName)

read

public List<LanguageProfile> read(String profileDirectory,
 Collection<String> profileFileNames)
                           throws IOException

Same as read(ClassLoader, String, java.util.Collection) using the class loader of this class.

Throws:

IOException

read

public List<LanguageProfile> read(Collection<String> profileFileNames)
                           throws IOException

Same as read(ClassLoader, String, java.util.Collection) using the class loader of this class, and the default profiles directory of this library.

Throws:

IOException

Throws:

IOException

readAll

public List<LanguageProfile> readAll(File path)
                              throws IOException
