Method Detail

parse

public NodeList parse(ExpTokenizer tokens)
               throws SyntaxError

Throws:

SyntaxError

parseBlock

public NodeList parseBlock(ExpTokenizer tokens)
                    throws SyntaxError

Parses a block of instructions. A block is 1 or more instructions. What is returned is a list of Nodes (instructions found). Each instruction has to finished off with a semicolon. This indicates the end of instructions and a new instruction can begin.

Throws:

SyntaxError

parseInstruction

public Node parseInstruction(ExpTokenizer tokens)
                      throws SyntaxError

Throws:

SyntaxError

parseEnumBlock

public NodeList parseEnumBlock(ExpTokenizer tokens)
                        throws SyntaxError

Parses a block of instructions. A block is 1 or more instructions. What is returned is a list of Nodes (instructions found). Each instruction has to finished off with a semicolon. This indicates the end of instructions and a new instruction can begin.

Throws:

SyntaxError

parseEnumInstruction

public Node parseEnumInstruction(ExpTokenizer tokens)
                          throws SyntaxError

Throws:

SyntaxError

parseListExpression

public java.util.ArrayList parseListExpression(ExpTokenizer tokens)
                                        throws SyntaxError

Lists are made up of any number and '-' and ',' characters. '-' means range. ie. 1-10 means all numbers through 10. ',' means a list. ie 1,2,5,6 means 1 & 2 & 5 & 6, excluding all other numbers.

Throws:

SyntaxError

setForceEnumConstants

public void setForceEnumConstants(boolean state)

By setting to true, enum constants will not be assigned labels, but the label constant name.

main

public static void main(java.lang.String[] args)
