getUTF8
public static int getUTF8(byte[] str, int start, int[] ch)
Return one less than the number of bytes used by the UTF-8 byte sequence. The Unicode char is returned in ch.- Parameters:
str
- points to the UTF-8 byte sequencestart
- starting offset in stringch
- initialised to 1st byte, passed as an array to allow modification- Returns:
- one less that the number of bytes used by UTF-8 char
-
putUTF8
public static int putUTF8(byte[] buf, int start, int c)
Store char c as UTF-8 encoded byte stream.- Parameters:
buf
- the bufferstart
- the start offsetc
- the char- Returns:
- the current position
-
flushLine
public void flushLine(Out fout, int indent, boolean shouldAddNewLine)
Flush the line.- Parameters:
fout
- where to write outputindent
- the indent amountshouldAddNewLine
-true
to add new line after flush
-
flushLine
public void flushLine(Out fout, int indent)
Flush the line.- Parameters:
fout

condFlushLine
public void condFlushLine(Out fout, int indent, boolean shouldAddNewLine)
Conditional flush the line.- Parameters:
fout
- where to write outputindent
- the indent amountshouldAddNewLine
-true
to add new line after flush
-
condFlushLine
public void condFlushLine(Out fout, int indent)
Conditional flush the line.- Parameters:
fout

printTree
public void printTree(Out fout, short mode, int indent, Lexer lexer, Node node)
- Parameters:
fout
- where to write outputmode
- the mode to useindent
