Field Details

precedence

private final Precedence precedence

The precedence of this MUnaryPostOperator object.

index

private int index

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

Constructor Details

MUnaryPostOperator

public MUnaryPostOperator(String name,
 int index,
 ArrayList<String> scan)

Creates a new MUnaryPostOperator object

Parameters:

name - The name that identifies this MUnaryPostOperator object

scan - The scanner tokens object that contains this object

Method Details

getPrecedence

public Precedence getPrecedence()

Returns:

the Precedence of this MOperator object.

validate

public boolean validate(ArrayList<String> scan)

Specified by:

validate in interface Validatable

Parameters:

scan - The scanner output that this MUnaryPostOperator 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 the grammatical usage of this token with repect to its 2 immediate neighbouring tokens to the left and to the right is correct.

assignCompoundTokens

public static void assignCompoundTokens(ArrayList<String> scan)

Carefully interpretes the correct arrangement of a loose math statement for objects of this class and applies the correct one to the Function object.

Parameters:

scan - The ArrayList object that is the scanner of the Function object and so contains this MUnaryPostOperator object
