Member Typedef Documentation

typedef MetaScope mirror::MetaContainer::scope

MetaScope reflecting the class or namespace this container belongs to.

The resulting MetaScope is a MetaClass for most containers, but it is for example the MetaGlobalScope for array containers.

Reimplemented from mirror::MetaScopedObject.

Member Function Documentation

static size_t mirror::MetaContainer::size_hint

(

Container &

container

)

[static]

Returns the number of elements in the container if possible.

This member function returns the number of elements in the container if this information is available for this Container type. If the info is not available this function returns zero.

friend struct default_traversal< MetaContainer > [friend]

The default element traversal method for the reflected container.

Meta-function returning a MetaTraversal which is providing meta-data about the default element traversal method for the container reflected by this MetaContainer

See also:

traversals

Returns:

MetaTraversal

friend struct erasers< MetaContainer > [friend]

The element removal methods available for the reflected container.

Meta-function returning a range of MetaErasers which are providing meta-data about all element removal methods for the container reflected by this MetaContainer

See also:

default_inserter

mp::range

Returns:

Range<MetaEraser>

friend struct inserters< MetaContainer > [friend]

The element insertion methods available for the reflected container.

Meta-function returning a range of MetaInserters which are providing meta-data about all element insertion methods for the container reflected by this MetaContainer

See also:

default_inserter

mp::range

Returns:

Range<MetaInserter>

friend struct is_a< MetaObject, ConceptTag > [friend, inherited]

Meta-function for checking if the MetaObject conforms to a concept.

This meta-function returns std::true_type if a MetaObject conforms to the concept identified by the ConceptTag. Returns std::false_type otherwise.

Returns:

BooleanConstantType

friend struct locators< MetaContainer > [friend]

The element location methods available for the reflected container.

Meta-function returning a range of MetaLocators which are providing meta-data about all element location methods for the container reflected by this MetaContainer

See also:

mp::range

Returns:

Range<MetaLocator>

friend struct scope< MetaScopedObject > [friend, inherited]

Meta-function returning the scope of the scoped object.

This meta-function "returns" the same MetaScope as the scope member typedef, but is better suited for algorithms using lambda placeholder expressions.

Returns:

MetaScope

friend struct traversals< MetaContainer > [friend]

The element traversal methods available for the reflected container.

Meta-function returning a range of MetaTraversals which are providing meta-data about all element traversal methods for the container reflected by this MetaContainer

See also:

default_traversal

mp::range

Returns:

Range<MetaTraversal>
