Constructor Detail

MUnaryPostOperator

public MUnaryPostOperator(java.lang.String name,
                          int index,
                          java.util.ArrayList<java.lang.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 Detail

getPrecedence

public Precedence getPrecedence()

Returns:

the Precedence of this MOperator object.

validate

public boolean validate(java.util.ArrayList<java.lang.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(java.util.ArrayList<java.lang.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
