Given a new variable name, lookup the source name, may return null if it's not found.

getOriginalNameToNewNameMap

public Map<String,String> getOriginalNameToNewNameMap()

Returns an unmodifiable mapping from original names to new names.

getNewNameToOriginalNameMap

public Map<String,String> getNewNameToOriginalNameMap()

Returns an unmodifiable mapping from new names to original names.

save

public void save(String filename)
          throws IOException

Saves the variable map to a file.

Throws:: IOException

load

public static VariableMap load(String filename)
                        throws IOException

Reads the variable map from a file written via save(String).

Throws:: IOException

toBytes

public byte[] toBytes()

Serializes the variable map to a byte array.

fromBytes

public static VariableMap fromBytes(byte[] bytes)
                             throws ParseException

Deserializes the variable map from a byte array returned by toBytes().

Throws:: ParseException

fromMap

public static VariableMap fromMap(Map<String,String> map)

Initializes the variable map from an existing map.

Parameters:: map - The map to use from original names to generated names. It is copied and changes to the specified map will not affect the returned object.
