Member Function Documentation

◆ New() [1/2]

static tmpNrc<T> New ( Args &&... args )

inlinestatic

Construct tmpNrc of T with forwarding arguments.

Parameters

args	list of arguments with which an instance of T will be constructed.

Note: Similar to std::make_shared, but the overload for array types is not disabled.

◆ NewFrom() [1/2]

static tmpNrc<T> NewFrom ( Args &&... args )

inlinestatic

Construct tmpNrc from derived type with forwarding arguments.

Parameters

args	list of arguments with which an instance of U will be constructed.

Note: Similar to New but for derived types

◆ isTmp()

bool isTmp ( ) const

inlinenoexcept

True if this is a managed pointer (not a const reference)

Definition at line 156 of file tmpNrcI.H.

Here is the caller graph for this function:

◆ empty()

bool empty ( ) const

inlinenoexcept

True if this is a non-null managed pointer.

Definition at line 163 of file tmpNrcI.H.

◆ valid()

bool valid ( ) const

inlinenoexcept

True if this is a non-null managed pointer, or is a const object reference

Definition at line 170 of file tmpNrcI.H.

◆ movable()

bool movable ( ) const

inlinenoexcept

True if this is a non-null managed pointer with a unique ref-count.

Definition at line 177 of file tmpNrcI.H.

◆ typeName()

Foam::word typeName ( ) const

inline

Return type-name of the tmp, constructed from type-name of T.

Definition at line 184 of file tmpNrcI.H.

◆ get() [1/2]

T * get ( )

inlinenoexcept

Return pointer without nullptr checking.

Definition at line 191 of file tmpNrcI.H.

◆ get() [2/2]

const T * get ( ) const

inlinenoexcept

Return the const object reference or a const reference to the contents of a non-null managed pointer.

Fatal for a null managed pointer
