Detailed Description

Iterator concept allowing to traverse over DeveloperExtensionsHandle collection.

Member Function Documentation

◆ DeveloperExtensionsIterator_GetKey()

error_type DeveloperExtensionsIterator_GetKey ( DeveloperExtensionsIteratorHandle *  handle,
NameObjectHandle **  result 
)

Get key at iterator position.

Ensure the iterator is valid.

DeveloperExtensionsIterator_IsValid

Friends And Related Function Documentation

◆ DeveloperExtensionsIterator_GetValue()

error_type DeveloperExtensionsIterator_GetValue ( DeveloperExtensionsIteratorHandle *  handle,
DeveloperExtensionHandle **  result 
)
related

Get value at iterator position.

Ensure the iterator is valid.

See also
DeveloperExtensionsIterator_IsValid

◆ DeveloperExtensionsIterator_IsValid()

error_type DeveloperExtensionsIterator_IsValid ( DeveloperExtensionsIteratorHandle *  handle,
DeveloperExtensionsHandle *  parent,
boolean_type *  result 
)
related

Determine if current position is valid.

Invalid position may mean that iterator moved past the end of the collection, as well as the collection was modified.

Any other operation except THIS will fail on invalid iterator.

◆ DeveloperExtensionsIterator_Next()

error_type DeveloperExtensionsIterator_Next ( DeveloperExtensionsIteratorHandle *  handle)
related

Advances iterator to the next position.

Ensure the iterator is valid.

See also
DeveloperExtensionsIterator_IsValid

◆ DeveloperExtensionsIterator_Release()

error_type DeveloperExtensionsIterator_Release ( DeveloperExtensionsIteratorHandle *  handle)
related

Decrement the internal reference counter.

When the internal counter reaches zero the object is deleted. Releasing already disposed object causes undefined behavior.
