Method Detail

registerParser

public static ExtensionParser<?> registerParser(ExtensionParser<?> parser)

Parameters:

parser - The ExtensionParser to register

Returns:

The replaced parser (by name) - null if no previous parser for this extension name

unregisterParser

public static ExtensionParser<?> unregisterParser(java.lang.String name)

Parameters:

name - The extension name - ignored if null/empty

Returns:

The removed ExtensionParser - null if none registered for this extension name

getRegisteredParser

public static ExtensionParser<?> getRegisteredParser(java.lang.String name)

Parameters:

name - The extension name - ignored if null/empty

Returns:

The registered ExtensionParser - null if none registered for this extension name

getRegisteredParsersNames

public static java.util.Set<java.lang.String> getRegisteredParsersNames()

getRegisteredParsers

public static java.util.List<ExtensionParser<?>> getRegisteredParsers()

supportedExtensions

public static java.util.Set<java.lang.String> supportedExtensions(java.util.Map<java.lang.String,?> parsed)

parse

public static java.util.Map<java.lang.String,java.lang.Object> parse(java.util.Map<java.lang.String,byte[]> extensions)

Parameters:

extensions - The received extensions in encoded form

Returns:

A Map of all the successfully decoded extensions where key=extension name (same as in the original map), value=the decoded extension value. Extensions for which there is no registered parser are ignored
