All Implemented Interfaces:

java.io.Serializable

public class LinearParserEvent

extends java.util.EventObject

The event sent during the parsing of a linear form of an expression.
Each event sent corresponds to token in the expression parsed. The tokens are the following :

• VARIABLE when a variable is encountered in the expression
• INTEGER when an integer is encountered in the expression
• FLOAT when a real number is encountered in the expression
• ADDITION when the + operator is encountered in the expression
• SUBSTRACTION when the - operator is encountered in the expression
• MULTIPLICATION when the * operator is encountered in the expression
• DIVISION when the / operator is encountered in the expression
• POWER when the ^ operator is encountered in the expression
• EQUAL when the = operator is encountered in the expression
• UNEQUAL when the <> operator is encountered in the expression
• LESS when the < operator is encountered in the expression
• LESSEQUAL when the <= operator is encountered in the expression
• GREATER when the > operator is encountered in the expression
• GREATEREQUAL when the >= operator is encountered in the expression
• FUNCTION when a name of a function (an function is expected to be an identificator immediately followed by an opening parenthesis) is encountered in the expression
• SEPARATOR when a separator (, or ;) is encountered in the expression
• OPEN_PAREN when an opening paranthesis is encountered in the expression
• CLOSE_PAREN when a closing paranthesis is encountered in the expression
• OPEN_BRACKET when an opening bracket is encountered in the expression
• CLOSE_BRACKET when a closing bracket is encountered in the expression
• OPEN_CURLY when an opening curly brace is encountered in the expression
• CLOSE_CURLY when a closing curly brace is encountered in the expression
• UNDERSCRIPT when the underscript (_) operator is encountered in the expression

There exists other token identifiers :

• RESERVED when a specific keyword (define in the property file of the parser) is encountered in the expression
• SPECIALIZED when a specialized operator is encountered in the expression.
  (not really clearly defined :o( )

Finally, 2 other token identifiers dealing with the parsing itself.

• START_EXPRESSION when the parsing of the expression starts
• END_EXPRESSION when the parsing of the expression ends
