Constructor & Destructor Documentation

AttributeStoreObserver()

GEO::AttributeStoreObserver::AttributeStoreObserver ( )

inline

Creates a new uninitialied AttributeStore.

Definition at line 76 of file attributes.h.

Member Function Documentation

dimension()

index_t GEO::AttributeStoreObserver::dimension ( ) const

inline

Gets the dimension.

Returns

the number of elements per item

Definition at line 108 of file attributes.h.

disconnect()

void GEO::AttributeStoreObserver::disconnect ( )

inline

Disconnects this AttributeStoreObserver from its AttributeStore.

This function is called whenever the AttributesManager is destroyed before the Attributes (can occur when using Lua scripting with Attribute wrapper objects).

Definition at line 141 of file attributes.h.

nb_elements()

index_t GEO::AttributeStoreObserver::nb_elements ( ) const

inline

Gets the total number of elements.

This corresponds to one position past the last valid index.

Returns

the total number of elements.

Definition at line 118 of file attributes.h.

notify()

void GEO::AttributeStoreObserver::notify ( Memory::pointer  base_addr, index_t  size, index_t  dim  )

inline

Callback function, called by the AttributeStore whenever it is modified.

Parameters

[in]	base_addr	new base address of the AttributeStore
[in]	size	new number of items in the AttributeStore
[in]	dim	new dimension, i.e. number of elements per item

Definition at line 88 of file attributes.h.

register_me()

void GEO::AttributeStoreObserver::register_me

(

AttributeStore *

store

)

Registers this observer to an AttributeStore.

Parameters

[in]

store

a pointer to the AttributeStore.

size()

index_t GEO::AttributeStoreObserver::size ( ) const

inline

Gets the size.

Returns

the number of items

Definition at line 100 of file attributes.h.

unregister_me()

void GEO::AttributeStoreObserver::unregister_me

(

AttributeStore *

store

)

Unregisters this observer from an AttributeStore.

Parameters

[in]

store

a pointer to the AttributeStore.
