Constructor Detail

BinaryOperator

public BinaryOperator(java.lang.String name,
                      int index,
                      java.util.ArrayList<java.lang.String> scan)

Parameters:

name - The bame of the operator

index - The index of the operator

scan - The scanner output

Method Detail

getPrecedence

public Precedence getPrecedence()

Returns:

the precedence of this operator

setIndex

public void setIndex(int index,
                     java.util.ArrayList<java.lang.String> scan)

Parameters:

index - sets the index of this operator in the scanned Function that it belongs to.

scan - The Function object that this object exists in.

getIndex

public int getIndex()

Returns:

the index of this operator in the scanned Function that it belongs to.

validate

public boolean validate(java.util.ArrayList<java.lang.String> scan)

Specified by:

validate in interface Validatable

Parameters:

scan - the Function object that this BinaryOperator object exists in. validates the grammatical usage of this operator (by leaving the correctFunction attribute of the function object un-modified) if the usage of this operator in its immediate environment i.e to its left and right is correct.

Returns:

true if valid
