overridevirtual |
Visitor pattern implementation.
Subclasses should implement this method as:
where T
is the name of the subclass, and shared_from_this() and ucast<>
are from Decompiler/Support/SmartPtr.h.
Implements retdec::llvmir2hll::Visitable.
Returns a clone of the value.
A clone is (in most cases) an exact copy of the value. This member function provides the copy mechanism for reference objects.
The following parts of values are not cloned:
The following subclasses of Value are not cloned, i.e. they are returned without any copying:
Statements in compound statements (i.e. statements where isCompound()
returns true
) are cloned without their successors; therefore, e.g., just the first statement of every if's clause is cloned.
Implements retdec::llvmir2hll::Value.

std::size_t retdec::llvmir2hll::StringType::getCharSize | ( | ) | const |
|
overridevirtual |
Returns true
if this value is equal to otherValue, false
otherwise.
This member function brings the support of value object semantics into reference objects, namely equality based not only on identity.
This function doesn't consider observers, metadata, etc.
Implements retdec::llvmir2hll::Value.
