Data.ObjectName
Description
Object names are explicitly handled identifiers for API objects, e.g. a
texture object name in OpenGL or a buffer object name in OpenAL. They come in
two flavors: If a name can exist on its own without an associated object, we
have a GeneratableObjectName, otherwise we have an ObjectName.
- class ObjectName a where
- class ObjectName a => GeneratableObjectName a where
Documentation
class ObjectName a where Source #
An ObjectName is an explicitly handled identifier for API objects, e.g. a
texture object name in OpenGL or a buffer object name in OpenAL.
Minimal complete definition
Methods
isObjectName :: MonadIO m => a -> m Bool Source #
Test if the given object name is currently in use, i.e. test if it has been generated, but not been deleted so far.
deleteObjectName :: MonadIO m => a -> m () Source #
Make the given object name available again, declaring it as unused.
deleteObjectNames :: MonadIO m => [a] -> m () Source #
Bulk version of deleteObjectName.
class ObjectName a => GeneratableObjectName a where Source #
A GeneratableObjectName is an ObjectName which can be generated without
creating an associated object at the same time, e.g. an OpenGL buffer object
name. Note that e.g. OpenGL program object names do not fall into this
category, because you can only create such a name together with a program
object itself.
Minimal complete definition
Methods
genObjectName :: MonadIO m => m a Source #
Generate a new unused object name. By generating the name, it becomes used.
genObjectNames :: MonadIO m => Int -> m [a] Source #
Bulk version of genObjectName.
