Detailed Description
template<typename value_t>
class CShaderParams< value_t >
Represents a mapping of name strings to value, for use with CShaderDefines (values are strings) and CShaderUniforms (values are vec4s).
Stored as interned vectors of name-value pairs, to support high performance comparison operators.
Not thread-safe - must only be used from the main thread.

◆ GetHash()
| size_t CShaderParams< value_t >::GetHash | ( | ) | const |
Return a hash of the current mapping.
◆ GetInterned()
|
staticprivate |
Returns a pointer to an SItems equal to items.
The pointer will be valid forever, and the same pointer will be returned for any subsequent requests for an equal items list.
◆ GetMap()
| std::map< CStrIntern, value_t > CShaderParams< value_t >::GetMap | ( | ) | const |
Return a copy of the current name/value mapping.
◆ operator!=()
|
inline |
Fast inequality comparison.
◆ operator<()
|
inline |
Compare with some arbitrary total order.
The order may be different each time the application is run (it is based on interned memory addresses).
◆ operator==()
|
inline |
Fast equality comparison.
◆ Set()
| void CShaderParams< value_t >::Set | ( | CStrIntern | name, |
| const value_t & | value | ||
| ) |
Add a name and associated value to the map of parameters.
If the name is already defined, its value will be replaced.
◆ SetMany()
| void CShaderParams< value_t >::SetMany | ( | const CShaderParams< value_t > & | params | ) |
Add all the names and values from another set of parameters.
If any name is already defined in this object, its value will be replaced.
