index

private int index

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

Constructor Details

MatrixBinaryOperator

public MatrixBinaryOperator(String name,
 int index,
 ArrayList<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 MBinaryOperator object belongs to.

Method Details

getPrecedence

public Precedence getPrecedence()

Returns:

the precedence of this operator

setIndex

public void setIndex(int index,
 ArrayList<String> scan)

Parameters:

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

scan - The scanner output

getIndex

public int getIndex()

Returns:

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

validate

public boolean validate(ArrayList<String> scan)

Specified by:

validate in interface Validatable

Parameters:

scan - the scanner output 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.
