CharBuf
Create a new buffer, link it viahost
to the calling text, and fill it with all character data from r.- Parameters:
r
- sourcebuf
- calling predecessorloc
- location of the start of the data- Throws:
IOException
-
CharBuf
Create a new buffer, link it viahost
to the calling text, and take the array s as its character data.- Parameters:
s
- a character store, directly used by the new buffer.buf
- calling predecessorloc
- location of the start of the data

Method Details

fill
Fill the data from all contents of the reader, until its "eof".- Throws:
IOException
-
bufferLA
public char bufferLA(int k) Look ahead to the next k-th character, either in its own data, or in the caller. The next-to-consume character is looked at with k=0(zero). -
bufferConsume
void bufferConsume()Advance position counter and line number, if linefeed is detected. Return to the including buffer, if this has reached its end, is made by the callerIncludingCharBuf.consume()
.Assume that all input is normalized to "\n" = "^J" = linefeed. (windows cr and apple cr-lf have been replaced.)
-
isNewline
boolean isNewline(char c) Decide if the next character is a newline. Assume that the input is normalized to "\n" = "^J" = linefeed. (windows cr and apple cr-lf have been replaced.)
