Member Function Documentation

ContainsItem()

bool ContainsItem ( const CompositeVariant &  item ) const

inlinenoexcept

Checks whether item is in this Composite.

Returns

true if item is in this composite; false if not.

Create()

static std::unique_ptr< Composite > Create ( CompositePurpose  purpose = CompositePurpose::Custom )

inlinestatic

Creates a composite with the given optional parameter.

Parameters

[in]

purpose

The purpose of this container.

Returns

Pointer to the created composite.

Exceptions

Any	exception derived from std::exception including CvbException.

FromHandle()

static std::unique_ptr< Composite > FromHandle ( HandleGuard< Composite > &&  guard )

inlinestatic

Creates a composite from a classic API handle.

Parameters

[in]

guard

Life time guard for C-API handle.

Returns

The composite created from the classic API handle.

Exceptions

Any	exception derived from std::exception including CvbException.

The composite takes ownership of the handle, so you must share it before using this function.

FromObject()

static CompositePtr FromObject ( std::shared_ptr< T >  object )

static

Returns a composite object from the given composite compatible object.

Parameters

[in]

object

A composite compatible object to share.

Returns

A composite that shares resources with the given object.

Examples

Cvb/CppPointCloudAcquisition.

Handle()

void * Handle ( ) const

inlinenoexcept

Classic API node handle.

Returns

Classic API handle.

Exceptions

Does	not throw any exception.

It is normally not necessary to work with this handle.

InsertItemAt()

void InsertItemAt ( int  index, const CompositeVariant &  item  )

inline

Insert a composite item specified at given index.

Parameters

[in]	index	Item index to insert the composite item at given index.
[in]	item	The composite item to insert.

Exceptions

Any	exception derived from std::exception including CvbException.

ItemAt()

CompositeVariant ItemAt ( int  index ) const

inline

Access to a composite item specified by its index.

Parameters

[in]

index

Item index of the composite item to access.

Returns

A variant.

Exceptions

Any	exception derived from std::exception including CvbException.

ItemCount()

int ItemCount ( ) const

inlinenoexcept

Number of variants in the composite.

Returns

Number of variants.

Exceptions

Does	not throw any exception.

Purpose()

CompositePurpose Purpose ( ) const

inlinenoexcept

Gets the purpose of this Composite.

Returns

The Cvb::CompositePurpose of this object.

PushBackItem()

void PushBackItem ( const CompositeVariant &  item )

inline

Appends a composite item.

Parameters

[in]

item

The composite item to append.

Exceptions

Any	exception derived from std::exception including CvbException.

RemoveItemAt()

void RemoveItemAt ( int  index )

inline

Remove a composite item specified by its index.

Parameters

[in]

index

Item index of the composite item to remove.

Exceptions

Any	exception derived from std::exception including CvbException.
