Parameters:

matrix - matrix to convert

Returns:

a String representation

getMatrixFromString

public MatrixND getMatrixFromString(String str)

Parse string as matrix representation. str must be in following format : - [name,dim,dimNames,semantics,data]

Parameters:

str -

Returns:

matrix representation

getDimToString

public String getDimToString(int[] dimArray)

Matrix dim to string.

Parameters:

dimArray - dim to convert.

Returns:

a String representation

getDimFromString

public int[] getDimFromString(String str)

String to matrix dim.

Parameters:

str - string to parse

Returns:

dim array

getDimensionNamesToString

public String getDimensionNamesToString(String[] dimNamesArray)

Dim names to string.

Parameters:

dimNamesArray - dim array to convert

Returns:

a String representation

getDimensionNamesFromString

public String[] getDimensionNamesFromString(String str)

String to dim names array.

Parameters:

str - string to parse

Returns:

a String representation

getSemanticsToString

public String getSemanticsToString(List<?>[] semanticsArray)

Semantics array to string.

Parameters:

semanticsArray - semantics array

Returns:

string names array

getSemanticsFromString

public List<?>[] getSemanticsFromString(String str)

String to semantics.

Parameters:

str - la chaine representant la semantique

semantics list

splitObjects

public List<?> splitObjects(String str)

Recréé chaque object de la chaine de caractere et l'ajoute dans une liste la chaine est de la forme. [null(), java.lang.String("toto"), ...]

Parameters:

str - la chaine representant

Returns:

semantics list

appendString

public StringBuffer appendString(StringBuffer buffer,
                                 Object o)
