Member Function Documentation

from_json()

void jimple_lengthof::from_json ( const json & )

overridevirtual

Initializes the current instance by parsing a JSON.

Parameters

json	The json object relative to the structure

Implements jimple_ast.

to_expr2t()

expr2tc jimple_lengthof::to_expr2t ( contextt & ctx, const std::string & class_name, const std::string & function_name ) const

overridevirtual

The IREP2 form of this expression.

The expression counterpart of jimple_method_field::to_code2t (K.4 of docs/roadmap/scope-jimple-irep2.md). A return type belongs to a virtual's signature, so the 27 to_exprt overrides cannot migrate one at a time; a parallel method can, with this default carrying whatever has not moved yet and shrinking as each override lands.

Reimplemented from jimple_expr.

to_string()

virtual std::string jimple_lengthof::to_string ( ) const

inlineoverridevirtual

Converts the object into a string.

Returns

a human readable string of the object

Implements jimple_ast.
