Method Detail

read

public LanguageProfile read(java.io.File profileFile)
                     throws java.io.IOException

Reads a LanguageProfile from a File in UTF-8.

Throws:

java.io.IOException

read

public LanguageProfile read(java.io.InputStream inputStream)
                     throws java.io.IOException

Reads a LanguageProfile from an InputStream in UTF-8.

Throws:

java.io.IOException

read

public java.util.List<LanguageProfile> read(java.lang.ClassLoader classLoader,
                                            java.lang.String profileDirectory,
                                            java.util.Collection<java.lang.String> profileFileNames)
                                     throws java.io.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:

java.io.IOException
