Detailed Description

A representation of a string type.

Use create() to create instances. Instances of this class have reference object semantics. This class is not meant to be subclassed.

Member Typedef Documentation

◆ SizeToStringTypeMap

using retdec::llvmir2hll::StringType::SizeToStringTypeMap = std::map<std::size_t, ShPtr<StringType> >
private

Mapping of sizes into StringType instances.

Constructor & Destructor Documentation

◆ StringType()

retdec::llvmir2hll::StringType::StringType ( std::size_t  charSize)
explicitprivate

Member Function Documentation

◆ accept()

virtual void retdec::llvmir2hll::StringType::accept ( Visitor v)
overridevirtual

Visitor pattern implementation.

Subclasses should implement this method as:

v->visit(ucast<T>(shared_from_this()));

where T is the name of the subclass, and shared_from_this() and ucast<> are from Decompiler/Support/SmartPtr.h.

Implements retdec::llvmir2hll::Visitable.

◆ clone()

virtual ShPtr<Value> retdec::llvmir2hll::StringType::clone ( )
overridevirtual

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:

  • predecessors and successors of statements

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.

◆ create()

static ShPtr<StringType> retdec::llvmir2hll::StringType::create ( std::size_t  charSize)
static

◆ getCharSize()

std::size_t retdec::llvmir2hll::StringType::getCharSize ( ) const

◆ isEqualTo()

virtual bool retdec::llvmir2hll::StringType::isEqualTo ( ShPtr< Value otherValue) 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.

Member Data Documentation

◆ charSize

std::size_t retdec::llvmir2hll::StringType::charSize
private

How large are characters in the string (in bits)?

◆ createdTypes

SizeToStringTypeMap retdec::llvmir2hll::StringType::createdTypes
staticprivate

Set of already created string types with characters of the given size.
