Method Detail

main

public static void main(String[] args)

advanceToNextEOL

public void advanceToNextEOL()

Description copied from class: CasParser

Advance to next End Of Line (EOL) or end of input. Is overriden by the subclasses that implement the actual parser.

Overrides:

advanceToNextEOL in class CasParser

nextLine

public final org.jdom.Element nextLine()
                                throws ParseException

Description copied from class: CasParser

Entry point for the recursive descendant parser. Is overriden by the subclasses that implement the actual parser. This function is to be used only if you want to handle the ParseException and TokenMgrError objects yourself. Normally it's better to call nextOmobj() that encapsulates all this and returns always an OMOBJ, which contains an OME (OM error) when there is some parsing error.

Overrides:

nextLine in class CasParser

Returns:

OpenMath object encoded as a JDOM tree.

Throws:

ParseException - Problem when parsing.

expr

public final org.jdom.Element expr()
                            throws ParseException

Throws:

ParseException

exprPrec1

public final org.jdom.Element exprPrec1()
                                 throws ParseException

Throws:

ParseException

exprPrec2

public final org.jdom.Element exprPrec2()
                                 throws ParseException

Throws:

ParseException

exprPrec3

public final org.jdom.Element exprPrec3()
                                 throws ParseException

Throws:
