Constructor Details

UnaryPostOperator

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

Creates a new UnaryPostOperator object

Parameters:

name - The name that identifies this UnaryPostOperator object

scan - The List object that contains the tokens

Method Details

getPrecedence

public Precedence getPrecedence()

Returns:

the Precedence of this Operator object.

validate

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

Specified by:

validate in interface Validatable

Parameters:

scan - the scanner-list object that this UnaryPostOperator 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 respect to its 2 immediate neighboring 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 MathExpression object. Examples: ²,³,-¹,!

Parameters:

scan - The ArrayList object that is the scanner of the MathExpression object and so contains this UnaryPostOperator object
