Constructor Summary

BinaryOperatorToken()
Default COnstructor - creates an operator with the value set to ' '

BinaryOperatorToken(char _operator, int _priority)
Constructor taking the operator and priority

Method Summary

boolean	equals(java.lang.Object object) Checks if an object is equal to this operator if object is a binary operator then it checks whether they have the same value otherwise it calls the super classes version

Constructor Detail

BinaryOperatorToken

public BinaryOperatorToken()

Default COnstructor - creates an operator with the value set to ' '

BinaryOperatorToken

public BinaryOperatorToken(char _operator,
                           int _priority)

Constructor taking the operator and priority

Parameters:

_operator - = the type of operator

_priority - = the priority of the operator

Method Detail

evaluate

public OperandToken evaluate(Token[] operands,
                             GlobalValues globals)

evaluate the operator

Specified by:

evaluate in class Token

Parameters:

operands - = the operators operands

Returns:

the result as and OperandToken

toString

public java.lang.String toString()

Convert the operator to a string

Specified by:

toString in class Token

Returns:

a string representation of the token

equals

public boolean equals(java.lang.Object object)

Checks if an object is equal to this operator if object is a binary operator then it checks whether they have the same value otherwise it calls the super classes version

Overrides:

equals in class java.lang.Object

Parameters:

object - = the object being tested against

Returns:

true if they are equal
