Constructor Detail

MBinaryOperator

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

Parameters:

name - the name that identifies the MBinaryOperator object

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

scan - the scanner tokens object that this MBinaryOperator object belongs to.

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 scanner tokens 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 scanner tokens object that this MBinaryOperator 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.
