Public Member Functions | |
| ShVariableNode (ShBindingType kind, int size, ShValueType valueType, ShSemanticType type=SH_ATTRIB) | |
| Constructs a VariableNode that holds a tuple of data of type. | |
| bool | uniform () const |
| Is this a uniform (non-shader specific) variable? | |
| bool | hasValues () const |
| Does this variable have values in the host, e.g. | |
| int | size () const |
| Get the number of elements in this variable. | |
| void | size (int size) |
| void | lock () |
| Do not update bound shaders in subsequent setValue calls. | |
| void | unlock () |
| Update bound shader values, and turn off locking. | |
| ShValueType | valueType () const |
| Returns index of the data type held in this node. | |
| std::string | name () const |
| Get this variable's name. | |
| void | name (const std::string &n) |
| Set this variable's name. | |
| bool | hasRange () |

Ensure this node has space to store host-side values. Normally this is not necessary, but when uniforms are given dependent programs and evaluated all the temporaries will need to store values during an evaluation. Definition at line 423 of file ShVariableNode.cpp. References SH::ShVariantFactory::generate(), m_size, m_valueType, m_variant, and SH::shVariantFactory(). Referenced by ShVariableNode(). |

Does this variable have values in the host, e.g. for constants and uniforms. Definition at line 127 of file ShVariableNode.cpp. References m_variant. |

Adds this to the declared temps set. If current parsing program has cfg node (i.e. this is a transformation, not a new program specification), then adds to programs entry node. Else adds an SH_OP_DECL as a dummy statement into current parsing block.

Ref-counted pointer to the variant. ShVariableNode is always the sole owner of this pointer once the node exists. Definition at line 227 of file ShVariableNode.hpp. Referenced by addVariant(), getVariant(), hasValues(), name(), setVariant(), and size(). |
