Method Detail

getTypeFromStream

Type getTypeFromStream(Lexer lexer)

Retrieve the type embedded as in $<type>1

Parameters:

lexer - the element that will give me the lexical logic

Returns:

the type from the scanner

generateConstant

boolean generateConstant(Lexer lexer,
                         char characterType)

Scan the stream unti a string that starts with the given character ends

Parameters:

lexer - the object in charge of managing the input stream

characterType, - is the starting character

Returns:

true on success

generateDollarNumber

boolean generateDollarNumber(Lexer lexer,
                             int elementCount,
                             Type type,
                             int sign)

$1, $2, $-3, etc detected. Proceed with the code generation

Parameters:

lexer - the element that will give me the lexical logic

elementCount - the number of elements in the rule

type - the type of the element

sign - is one for possitive, or -1 for negative

Returns:

true if everything is OK

generateDollarDollar

boolean generateDollarDollar(Lexer lexer,
                             int elementCount,
                             String nonTerminalId,
                             Type type)

$$ detected. Proceed with the code generation

Parameters:

lexer - the element that will give me the lexical logic

elementCount - the number of elements in the rule

nonTerminalId - the non terminal id for the rule

type - the type of the element

Returns:

true if everything is OK

generateDollarLetter

boolean generateDollarLetter(Lexer lexer,
                             int elementCount,
                             Type type,
                             String nonTerminalId)

$Letter was detected. The idea is to transform such occurrences into $$ or $digit occurrences by looking at the symbol whose name is given by the identifier.

When two rule items have the same symbol, a disambiguating index like $Symbol[1], $Symbol[2], etc. can be used. The Left hand symbol is only used when non indexed;

Parameters:

lexer - the element that will give me the lexical logic

elementCount - the number of elements in the rule

nonTerminalId - the non terminal id for the rule

type - the type of the element

Returns:

true if everything is OK

skipAndOutputCompositeComment

boolean skipAndOutputCompositeComment(Lexer lexer,
                                      char secondaryCharacter,
                                      char primaryCharacter)

Skip a comment, and copying it to the output

Parameters:

lexer - the element that will give me the lexical logic

primaryCharacter, - for example /

secondaryCharacter, - for example *

Returns:

true on success
