Fields
Name | Description |

open isNumber: Boolean
|
Checks whether the current term is a number, i.e., either an integer or a real number.
This method is guaranteed to return |
open variables: Sequence<Var>
|
The sequence of Variables directly or indirectly contained in the current term. Variables are lazily returned in a non-deterministic order. Notice that no occurrence-check is performed. Thus, if a Term contains the same Variable twice or more times, then the variables sequence may contain as many occurrences of that Variable |

abstract fun freshCopy(): Numeric
ReturnValue
Name | Description |
---|---|
Numeric
|
a fresh copy of the current term which is different because variables are consistently renamed |

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.
