throws ParseException
- Throws:
ParseException
restart
public void restart(java.io.Reader stream,
Jep jep,
java.util.ArrayList<java.lang.String> errorList)
- Restart the parse with the given stream.
- Since:
- 2.3.0 beta 1
continueParse
public Node continueParse()
throws ParseException
- Continue parsing without re-initilising stream.
Allows reentrance of parser so that strings like
"x=1; y=2; z=3;" can be parsed.
When a semi colon is encountered parsing finishes leaving the rest of the string unparsed.
Parsing can be resumed from the current position by using this method.
For example
XJep j = new XJep();
Parser parse = j.getParse();
StringReader sr = new StringReader("x=1; y=2; z=3;");
parse.restart(sr,j);
Node node;
try {
while((node = j.continueParse())!=null) {
j.println(node);
} }catch(ParseException e) {}
- Throws:
ParseException
setInitialTokenManagerState
public void setInitialTokenManagerState(int state)
- Sets the initial state that the token manager is in.
Can be used to change how x.x is interpreted, either as a single
identifier (DEFAULT) or as x x (NO_DOT_IN_IDENTIFIERS)
- Parameters:
state
- the state to be in. Currently the only legal values are DEFAULT and NO_DOT_IN_IDENTIFIER
