Member Function Documentation

cast()

void* meta::base::cast ( void *  instance ) const

inlinenoexcept

Casts an instance from a parent type to a base type.

Parameters

instance

The instance to cast.

Returns

An opaque pointer to the base type.

Definition at line 857 of file meta.hpp.

operator bool()

meta::base::operator bool ( ) const

inlineexplicitnoexcept

Returns true if a meta object is valid, false otherwise.

Returns

True if the meta object is valid, false otherwise.

Definition at line 865 of file meta.hpp.

operator==()

bool meta::base::operator== ( const base &  other ) const

inlinenoexcept

Checks if two meta objects refer to the same node.

Parameters

other

The meta object with which to compare.

Returns

True if the two meta objects refer to the same node, false otherwise.

Definition at line 875 of file meta.hpp.

parent()

meta::type meta::base::parent ( ) const

inlinenoexcept

Returns the meta type to which a meta base belongs.

Returns

The meta type to which the meta base belongs.

Definition at line 1960 of file meta.hpp.

type()

meta::type meta::base::type ( ) const

inlinenoexcept

Returns the meta type of a given meta base.

Returns

The meta type of the meta base.
