Integer

interface Integer: Numeric, Any

Fields

Name Description
open isInt: Boolean

Checks whether the current term is an integer. This method is guaranteed to return true if and only if the current term is an instance of Integer.

abstract value: BigInteger
open decimalValue: BigDecimal
open intValue: BigInteger

Methods

freshCopy

open fun freshCopy(): Integer

Returns a fresh copy of this Term, that is, an instance of Term which is equal to the current one in any aspect, except variables directly or indirectly contained into this Term, which are refreshed. This means that it could return itself, if no variable is present (ground term), or a new Term with freshly generated variables.

Variables are refreshed consistently, meaning that, if more variables exists within this Term having the same name, all fresh copies of such variables will have the same complete name.

Example: "f(X, g(X))".freshCopy() returns something like "f(X_1, g(X_1))" instead of "f(X_1, g(X_2))"

Notice that, if the current term is ground, the same object may be returned as a result by this method.

ReturnValue

Name Description
Integer

a fresh copy of the current term which is different because variables are consistently renamed

freshCopy

open fun freshCopy(scope: Scope): Integer

Returns a fresh copy of this Term, similarly to freshCopy, possibly reusing variables from the provided scope, if any

Parameters

Name Description
scope: Scope

the Scope containing variables to be used in copying

ReturnValue

Name Description
Integer

a fresh copy of the current term which is different because variables are consistently renamed
