sealed abstract class GeneralData extends AnyRef
General formula annotation data. Can be one of the following:
- MetaFunctionData, a term-like meta expression: either a (meta-)function or a (meta-)constant.
- MetaVariable, a term-like meta expression that captures a variable.
- NumberData, a numerical value.
- DistinctObjectData, an expression that represents itself.
- GeneralFormulaData, an expression that contains object-level formula expressions.

See GeneralTerm for some context and http://tptp.org/TPTP/SyntaxBNF.html#general_term for a use case.

This is the documentation for the Scala TPTP parser used, e.g., by the Leo-III prover.
Package structure
The leo package contains two sub-packages as follows:
leo.datastructures
contains the leo.datastructures.TPTP object that bundles the different abstract syntax tree (AST) representations for the different TPTP language dialects, including ...leo.datastructures.TPTP.THF
- Higher-order formulas (THF)leo.datastructures.TPTP.TFF
- Typed first-order formulas (TFF)leo.datastructures.TPTP.FOF
- Untyped first-order formulas (FOF)leo.datastructures.TPTP.TCF
- Typed clausal form (TCF)leo.datastructures.TPTP.CNF
- Untyped clausal form (CNF)leo.modules.input
- the parser itself.Usage (in short)
The leo.modules.input.TPTPParser offers several parsing methods:
