Constructor Detail

TranslationMap

public TranslationMap()

Reads a file and put it in a string.

Method Detail

put

public java.lang.String put(java.lang.String suggestedName,
                            java.lang.Object instance)

Insert an object into 'this' map.
A new instance (the object to insert) is inserted with the suggested name if the name and the object are not present in the map.

• If the instance is already present: does not insert anything.
• If the name is already present: change the suggested name so that it results unique and inserts the instance with such unique name.

Parameters:

suggestedName - suggested name for the instance.

instance - the object to insert.

Returns:

the name choosen for the instance.

getUniqueName

private java.lang.String getUniqueName(java.lang.String suggestedName,
                                       java.util.Map inMap)

Starting from the suggested Name computes an unique name on the map inMap.

Returns:

a not existing name in the map inMap.

get

public java.lang.Object get(java.lang.String name)

Search for the object related to the given name.

Returns:

null if the instance is not found.

putName

public java.lang.String putName(java.lang.String stringToTranslate)

Insert a string into 'this' map.
The methods putName and getName are designed to translate uniquely names between ODL and OLCD.
Since OLCD supports names with maximum length of 15 chars this routine will truncate chars to 15 chars preserving uniquely (I mean, the same name will be translated ever and only in a given mode).

Parameters:

stringToTranslate - name to be truncated.

Returns:

the truncated unique name.

getName

public java.lang.Object getName(java.lang.String name)

Name Mapping. Search for the fullName related to the given truncated name.

Returns:

null if the instance is not found.

toStringOld

public java.lang.String toStringOld()

String representation.

main

public static void main(java.lang.String[] args)

Routine used to test the class.

Tests the tools.
