class AttributeManager ​

This class manages all its associated Attributes. Each Attribute is registered and can be retrieved by a given name.

Functions ​

AttributeManager ​

cpp
public void AttributeManager(const AttributeManager & )
public void AttributeManager(const AttributeManager & )

operator= ​

cpp
public AttributeManager & operator=(const AttributeManager & )
public AttributeManager & operator=(const AttributeManager & )

public void ~AttributeManager()
public void ~AttributeManager()

find_generic_attribute ​

cpp
public shared_ptr find_generic_attribute(basic_string_view name)
public shared_ptr find_generic_attribute(basic_string_view name)

Recover the non-typed/generic Attribute from the attribute name. This can be used when attribute type is not known in a context.

name [in] The associated attribute name to look for.

return nullptr if no attribute matches the given name.

find_attribute ​

cpp
public std::shared_ptr<ReadOnlyAttribute<T> > find_attribute(basic_string_view name)
public std::shared_ptr<ReadOnlyAttribute<T> > find_attribute(basic_string_view name)

Recover the typed Attribute from the attribute name

name [in] The associated attribute name to look for

T The type to of the ReadOnlyAttribute element

exceptionif no Attribute found

find_or_create_attribute ​

cpp
public std::shared_ptr<Attribute<T> > find_or_create_attribute(basic_string_view name, T default_value, AttributeProperties properties)
public std::shared_ptr<Attribute<T> > find_or_create_attribute(basic_string_view name, T default_value, AttributeProperties properties)

Recover or create the attribute from the manager and the attribute name. If the recovered Attribute is not a of the same type than the attribute, it replaces it by the Attribute corresponding to the attribute.

name [in] The associated attribute name to look for

default_value [in] The default value to use when new attribute element are created

properties [in] The AttributeProperties to set the attribute flags for future modifications

Attribute The attribute type to look for, such as ConstantAttribute

T The type of the Attribute element

exceptionif the Attribute replacement failed

find_or_create_attribute ​

cpp
public std::shared_ptr<Attribute<T> > find_or_create_attribute(basic_string_view name, T default_value)
