sealed abstract class ConcreteTerm extends Term
Base class for all concrete terms.
A ConcreteTerm guarantees
that the type of the term (App,Const,Abs...) corresponds to the top-level
constructor on Isabelle side ($, Const, Abs, ...).

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.

disconnectFromIsabelle(): Unit
Forgets the MLValue associated with this term.
Forgets the MLValue associated with this term. Note that the method mlValue will automatically create a new one when invoked. Will be ignored for MLValueTerms (because those cannot recover the term structure without the MLValue)

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.

This can be useful to constructing human readable messages about this value.
