Detailed Description

A type representing function types.

A FunctionType is represents the type of a function. It provides access to the return type, and number and types of the arguments.

Member Typedef Documentation

Data

using KDevelop::FunctionType::Data = FunctionTypeData

Definition at line 121 of file functiontype.h.

Ptr

using KDevelop::FunctionType::Ptr = TypePtr<FunctionType>

Definition at line 27 of file functiontype.h.

Member Enumeration Documentation

anonymous enum

anonymous enum

Enumerator
Identity

Definition at line 117 of file functiontype.h.

SignaturePart

enum KDevelop::FunctionType::SignaturePart

An enumeration of sections of the function signature that can be returned.

Enumerator
SignatureWhole	When this is given to toString(..), a string link "RETURNTYPE (ARGTYPE1, ARGTYPE1, ..)" is returned.
SignatureReturn	When this is given, only a string that represents the return-type is returned.
SignatureArguments	When this is given, a string that represents the arguments like "(ARGTYPE1, ARGTYPE1, ..)" is returned. This does not include a trailing "const" if the function is constant

Constructor & Destructor Documentation

FunctionType() [1/3]

KDevelop::FunctionType::FunctionType

(

)

Default constructor.

Definition at line 63 of file functiontype.cpp.

FunctionType() [2/3]

KDevelop::FunctionType::FunctionType

(

const FunctionType &

rhs

)

Copy constructor.

Parameters

rhs	type to copy

Definition at line 21 of file functiontype.cpp.

FunctionType() [3/3]

KDevelop::FunctionType::FunctionType ( FunctionTypeData &  data )

explicit

Constructor using raw data.

Parameters

data	internal data.

Definition at line 25 of file functiontype.cpp.

~FunctionType()

KDevelop::FunctionType::~FunctionType ( )

override

Destructor.

Definition at line 68 of file functiontype.cpp.

Member Function Documentation

accept0()

void KDevelop::FunctionType::accept0 ( TypeVisitor *  v ) const

overrideprotectedvirtual

Visitor method, reimplement to allow visiting of types.

Parameters

v	visitor which is visiting.

Implements KDevelop::AbstractType.

Definition at line 115 of file functiontype.cpp.

addArgument()

void KDevelop::FunctionType::addArgument	(	const AbstractType::Ptr &	argument,
		int	index = -1
	)

Add an argument to the function, specifying what type it takes.

Parameters

argument	the argument's type
index	where to insert the argument; the default "-1" will insert it at the end of the list

Definition at line 72 of file functiontype.cpp.

arguments()

QList< AbstractType::Ptr > KDevelop::FunctionType::arguments

(

)

const

Retrieve the list of types of the function's arguments.

Returns

the argument types.

Todo:

Don't do the conversion

Definition at line 95 of file functiontype.cpp.

clone()

AbstractType * KDevelop::FunctionType::clone ( ) const

overridevirtual

Should create a clone of the source-type, with as much data copied as possible without breaking the du-chain.

Implements KDevelop::AbstractType.

Definition at line 29 of file functiontype.cpp.

equals()

bool KDevelop::FunctionType::equals ( const AbstractType *  rhs ) const

overridevirtual

Should return whether this type's content equals the given one Since this is used by the type-repository, it must compare ALL members of the data type.

Reimplemented from KDevelop::AbstractType.

Definition at line 34 of file functiontype.cpp.

exchangeTypes()

void KDevelop::FunctionType::exchangeTypes ( TypeExchanger *  exchanger )

overridevirtual

Should, like accept0, be implemented by all types that hold references to other types.

If this is called on one type, that type should call exchangeTypes(..) with all its referenced sub-types. The type itself does not recurse into the sub-types, that can be done by the exchanger itself if desired.

Reimplemented from KDevelop::AbstractType.

Definition at line 128 of file functiontype.cpp.

hash()

uint KDevelop::FunctionType::hash ( ) const

overridevirtual

A hash-value that should have the following properties:

• When two types match on equals(), it should be same.
• When two types don't match on equals(), it should be different with a high probability.

Reimplemented from KDevelop::AbstractType.

Definition at line 171 of file functiontype.cpp.

indexedArguments()

const IndexedType * KDevelop::FunctionType::indexedArguments

(

)

const

Returns the same arguemtns as arguments(), but without converting them to a QList.

This is much faster, and should be preferred for very tight loops when the performance counts.

Returns

an array that contains the arguments. For the count of arguments, call indexedArgumentsSize

Definition at line 105 of file functiontype.cpp.

indexedArgumentsSize()

uint KDevelop::FunctionType::indexedArgumentsSize

(

)

const

Returns the size of the array returned by indexedArguments().

This is much faster than working with arguments().

Definition at line 110 of file functiontype.cpp.

operator=()

FunctionType& KDevelop::FunctionType::operator= ( const FunctionType &  rhs )

delete

partToString()

QString KDevelop::FunctionType::partToString ( SignaturePart  sigPart ) const

virtual

This function creates a string that represents the requested part of this function's signature.

Parameters

sigPart

part of the signature requested.

Returns

the signature as text.

Definition at line 137 of file functiontype.cpp.

removeArgument()

void KDevelop::FunctionType::removeArgument

(

int

i

)

Remove the argument with number i from the function.

Parameters

i	index (starting from 0 with the first argument) to remove

Definition at line 80 of file functiontype.cpp.

returnType()

AbstractType::Ptr KDevelop::FunctionType::returnType

(

)

const

Retrieve the return type of the function.

Returns

the return type.

Definition at line 90 of file functiontype.cpp.

setReturnType()

void KDevelop::FunctionType::setReturnType

(

const AbstractType::Ptr &

returnType

)

Sets the return type of the function.

Parameters

returnType

the return type.

Definition at line 85 of file functiontype.cpp.

toString()

QString KDevelop::FunctionType::toString ( ) const

overridevirtual

Returns this type as a string, preferably the same as it is expressed in the code.

Returns

this type as a string

Reimplemented from KDevelop::AbstractType.

Definition at line 161 of file functiontype.cpp.

whichType()

AbstractType::WhichType KDevelop::FunctionType::whichType ( ) const

overridevirtual

Determine which data type this abstract type represents.

Returns

the data type represented by this type.

Reimplemented from KDevelop::AbstractType.

Definition at line 166 of file functiontype.cpp.
