Method Detail

main

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

labelConvention

public static java.lang.String labelConvention(java.lang.String label)

Label convention check for using with data structures that require element labels such as Hierarchy or DIFGraph. Following is the definition for strings acceptable by this method:

        digit = ['0' .. '9']
        non_digit = [[['a' .. 'z'] + ['A' .. 'Z']] + '_']
        s_char = [all -['"' + ['\' + [10 + 13]]]] | escape_sequence;
        s_char_sequence = s_char*;

        label = non_digit (digit | non_digit)*
        or
        label = '$' s_char_sequence '$';
        

This definition is compatible with DIF Language definition in mapss/dif/language/sablecc/Compiler.grammar.

Parameters:

label - String to check.

Returns:

Error string. Null in case of no errors.

typeConvention

public static java.lang.String typeConvention(java.lang.String label)

Type convention check for DIF actor attribute type. Note that '$' s_char_sequence '$' is not allowed in this method. Following is the definition for strings acceptable by this method:

        digit = ['0' .. '9']
        non_digit = [[['a' .. 'z'] + ['A' .. 'Z']] + '_']
        label = non_digit (digit | non_digit)* ('.' non_digit (digit | non_digit)* )*;
        

Parameters:

label - String to check.

Returns:

Error string. Null in case of no errors.

datatypeConvention

public static java.lang.String datatypeConvention(java.lang.String label)

Type convention check for DIF actor attribute type. Note that '$' s_char_sequence '$' is not allowed in this method. Following is the definition for strings acceptable by this method:

        digit = ['0' .. '9']
        non_digit = [[['a' .. 'z'] + ['A' .. 'Z']] + '_']
        label = non_digit (digit | non_digit)* ('.' non_digit (digit | non_digit)* )*;
        

Parameters:

label - String to check.

Returns:

Error string. Null in case of no errors.
