Detailed Description

abstract base class for text editors

Member Function Documentation

◆ call_void()

bool cgv::base::base::call_void ( const std::string &  method,
const std::vector< std::string > &  param_value_types,
const std::vector< const void * > &  param_value_ptrs,
const std::string &  result_type = "",
void *  result_value_ptr = 0 
)
virtualinherited

abstract interface to call an action

overload to implement the execution of a method based on the method name and the given parameters

, i.e. a class method based on the action name and the given parameters. The default implementation uses the self_reflect() method to dispatch this call. If not found, the get_void method returns false.

◆ find_member_ptr()

void * cgv::base::base::find_member_ptr ( const std::string &  property_name,
std::string *  type_name = 0 
)
inherited

find a member pointer by name.

If not found the null pointer is returned. If the type name string pointer is provided, the type of the property is copied to the referenced string.

◆ get()

template<typename T >
T cgv::base::base::get ( const std::string &  property)
inlineinherited

query a property of the element and perform standard conversions if necessary.

This templated version simply extracts the type of the value from the reference and calls the set_void() method. Note that this only works if the template cgv::type::info::type_name<T> is overloaded for the value type.

◆ get_property_declarations()

std::string cgv::base::base::get_property_declarations ( )
virtualinherited

return a semicolon separated list of property declarations

return a semicolon separated list of property declarations of the form "name:type", by default an empty list is returned

of the form "name1:type1;name2:type2;...", by default an empty list is returned. The types should by consistent with the names returned by cgv::type::info::type_name::get_name. The default implementation extracts names and types from the self_reflect() method and the meta type information provided by the get_type() method.

Reimplemented in cgv::base::factory, cgv::base::base_generator, cgv::media::image::image_reader, cgv::media::video::video_writer, cgv::media::image::image_writer, cgv::media::video::video_reader, and cgv::base::console.

◆ get_user_data()

void * cgv::base::base::get_user_data ( ) const
virtualinherited

this virtual method allows to pass application specific data for internal purposes

this virtual method allows derived classes to pass application specific data

◆ get_void()

bool cgv::base::base::get_void ( const std::string &  property,
const std::string &  value_type,
void *  value_ptr 
)
virtualinherited

abstract interface for the getter of a dynamic property.

abstract interface for the getter, by default it simply returns false

The default implementation uses the self_reflect() method to find a member with the given property as name. If not found, the get_void method returns false.

Reimplemented in cgv::base::factory, cgv::base::base_generator, cgv::base::console, cgv::media::image::image_reader, cgv::media::image::image_writer, cgv::media::video::video_reader, and cgv::media::video::video_writer.

◆ is_property()

bool cgv::base::base::is_property ( const std::string &  property_name,
std::string *  type_name = 0 
)
inherited

check if the given name specifies a property.

If the type name string pointer is provided, the type of the property is copied to the referenced string.

◆ multi_set()

void cgv::base::base::multi_set ( const std::string &  property_assignments,
bool  report_error = true 
)
inherited

set several properties

set several properties, which are defined as colon separated assignments, where the types are derived automatically

, which are defined as colon separated assignments, where the types are derived automatically to bool, int, double or std::string.

◆ on_register()

void cgv::base::base::on_register ( )
virtualinherited

overload to handle register events that is sent after the instance has been registered

overload to return a type info structure. By default an empty pointer is returned.

◆ self_reflect()

bool cgv::base::base::self_reflect ( cgv::reflect::reflection_handler )
virtualinherited

used for simple self reflection

is used by default implementation of set_void, get_void and get_property_declarations

The overloaded implementation is used by the default implementations of set_void, get_void and get_property_declarations with corresponding reflection handlers. The default implementation of self_reflect is empty.

Reimplemented in cgv::render::render_config, and cgv::render::shader_config.

◆ set()

template<typename T >
void cgv::base::base::set ( const std::string &  property,
const T &  value 
)
inlineinherited

set a property of the element to the given value and perform standard conversions if necessary.

This templated version simply extracts the type of the value from the reference and calls the set_void() method. Note that this only works if the template cgv::type::info::type_name<T> is overloaded for the value type.

◆ set_void()

bool cgv::base::base::set_void ( const std::string &  property,
const std::string &  value_type,
const void *  value_ptr 
)
virtualinherited

abstract interface for the setter of a dynamic property.

abstract interface for the setter, by default it simply returns false

The default implementation uses the self_reflect() method to find a member with the given property as name. If not found, the set_void method returns false.

Reimplemented in cgv::base::factory, cgv::base::base_generator, cgv::base::console, cgv::media::image::image_reader, cgv::media::image::image_writer, cgv::media::video::video_reader, and cgv::media::video::video_writer.
