Functions

LA

dchar LA(int i)

UTF-8 coded character mapped to UTF-32 @uml @override

Undocumented in source. Be warned that the author may not have intended to support it.

consume

void consume()

@uml @override

getSourceName

string getSourceName()

@uml @override

getText

string getText(Interval interval)

@uml @override

index

size_t index()

@uml @override

load

void load(File r)

Undocumented in source. Be warned that the author may not have intended to support it.

mark

int mark()

mark/release do nothing; we have entire buffer @uml @override

release

void release(int marker)

@uml @override

reset

void reset()

Reset the stream so that it's in the same state it was when the object was created *except* the data array is not touched.

seek

void seek(size_t index)

consume() ahead until index_of_next_character==index; can't just set index_of_next_character=index as we must update line and charPositionInLine. If we seek backwards, just set index_of_next_character @uml @override

size

size_t size()

@uml @override

toString

string toString()

@uml @override

Variables

cp_in_buffer

size_t cp_in_buffer;

How many UCS code_points are actually in the buffer

data

char[] data;

The UTF-8 data being scanned

index_of_next_char

size_t index_of_next_char;

index of next UTF-8 character

name

string name;

What is name or source of this char stream?

Inherited Members

From CharStream

getText

string getText(Interval interval)

This method returns the text for a range of characters within this input stream. This method is guaranteed to not throw an exception if the specified {@code interval} lies entirely within a marked range. For more information about marked ranges, see {@link IntStream#mark}.
