final class Abs extends ConcreteTerm
A lambda abstraction (ML constructor Abs). name is the name of the bound variable,
typ is the type of the bound variable, and body is the body of the lambda abstraction.
E.g., λx. x would be represented as Abs("x",typ, Bound(0)) for suitable typ.
Note that name is for informative purposes only (i.e., it has no logical relevance)
since deBrujn indices are used. name can even be "".

disconnectFromIsabelle(): Unit
Forgets the MLValue associated with this term.

def
equals(that: Any): Boolean
Equality of terms.
Equality of terms. Returns true iff the two Term instances represent the same term in the Isabelle process. (E.g., a Cterm and a Const can be equal.) May throw an exception if the computation of the terms fails. (But will not fail if await or a related FutureValue method has returned successfully on both terms.)
As a side effect, comparing two terms makes their mlValues equal (if the equality test returned true). This means that comparing terms can reduce memory use on the Isabelle side (because duplicate terms are released), and future equality checks will be faster. Note: if both compared values already have ML Values, then the one from
thiswill be copied tothat(so the order matters).- Definition Classes

fastType: Typ
Returns the type of this term, assuming the term is well-typed.
Returns the type of this term, assuming the term is well-typed. (The function does not verify whether the term is indeed well-typed. If it is not, no guarantee is made what type is returned.)
This method is analogous to
fastype_ofin Isabelle/ML but avoids transferring the term to/from Isabelle when determining the type.- Definition Classes

mlValue: MLValue[Term]
Transforms this term into an MLValue containing this term.
Transforms this term into an MLValue containing this term. This causes transfer of the term to Isabelle only the first time it is accessed (and not at all if the term came from the Isabelle process in the first place).
The MLValue can change over time but will always be an MLValue for an equal term.

Produces a string representation of this object.
Produces a string representation of this object. Uses the Isabelle pretty printer.

Instance of Symbols for converting to Unicode. Default: global default instance Symbols.globalInstance. Use prettyRaw to avoid conversion to Unicode.

lazy val
someFuture: Future[Any]
Returns a future that completes when the computation of this object is complete.
Returns a future that completes when the computation of this object is complete. (Or that holds an exception if that computation throws an exception.) However, upon successful completion, the future may return an arbitrary (and thus useless) value. May be faster to implement than forceFuture because there may be already a future available but that returns the wrong value.

A utility method that returns "" if this value was successfully computed, " (computing)" if it still computes, and " (failed)" if it finished with an exception.

toString: String
Produces a string representation of this term.
Produces a string representation of this term.
This is not a "pretty" representation, it does not use Isabelle syntax, and subterms that are stored only in the Isabelle process are replaced with a placeholder (thus this method does not invoke any potentially communication with the Isabelle process).
