Detailed Description

A representation of a pointer type.

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

Constructor & Destructor Documentation

◆ PointerType()

retdec::llvmir2hll::PointerType::PointerType ( ShPtr< Type containedType)
private

Constructs a new pointer type.

See create() for more information.

Member Function Documentation

◆ accept()

void retdec::llvmir2hll::PointerType::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()

ShPtr< Value > retdec::llvmir2hll::PointerType::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()

ShPtr< PointerType > retdec::llvmir2hll::PointerType::create ( ShPtr< Type containedType)
static

Creates a new pointer type.

Parameters
[in]containedTypeContained type.
Preconditions
  • containedType is non-null

◆ getContainedType()

ShPtr< Type > retdec::llvmir2hll::PointerType::getContainedType ( ) const

Returns the contained type.

◆ isEqualTo()

bool retdec::llvmir2hll::PointerType::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.

◆ setContainedType()

void retdec::llvmir2hll::PointerType::setContainedType ( ShPtr< Type newContainedType)

Sets a new contained type.

Preconditions
  • newContainedType is non-null

Member Data Documentation

◆ containedType

ShPtr<Type> retdec::llvmir2hll::PointerType::containedType
private

Contained type.
