| ShVariable (const ShVariableNodePtr &node, const ShSwizzle &swizzle, bool neg) | |
| ShVariable & | operator= (const ShProgram &prg) |
| bool | null () const |
| true iff node is a null pointer. | |

| const ShVariableNodePtr & | node () const |
| Obtain the actual node this variable refers to. | |
| bool | neg () const |
| Return true if this variable is negated. | |
| bool & | neg () |
| ShVariantPtr | getVariant () const |
| Returns a copy of the variant (with swizzling & proper negation). | |
| ShVariantPtr | getVariant (int index) const |
| bool | loadVariant (ShVariant *&result) const |
| Sets result to this' variant if possible. | |
| void | updateVariant () |
| void | setVariant (const ShVariant *other, bool neg, const ShSwizzle &writemask) |
| Sets the elements of this variant from other accounting for this' writemask and negations. | |
| void | setVariant (ShVariantCPtr other, bool neg, const ShSwizzle &writemask) |
| void | setVariant (const ShVariant *other, int index) |
| Sets the indicated element of this' variant from other. | |
| void | setVariant (ShVariantCPtr other, int index) |
| void | setVariant (const ShVariant *other) |
| Sets this' variant from the contents of other. | |
| void | setVariant (ShVariantCPtr other) |
| ShVariable | operator() () const |
| Identity swizzle. | |
| ShVariable | operator() (int) const |
| ShVariable | operator() (int, int) const |
| ShVariable | operator() (int, int, int) const |
| ShVariable | operator() (int, int, int, int) const |
| ShVariable | operator() (int size, int indices[]) const |
| ShVariable | operator- () const |
| bool | operator== (const ShVariable &other) const |
| bool | operator!= (const ShVariable &other) const |
| void | clone (const ShVariable &other) |
Metadata | |
| void | rangeVariant (const ShVariant *low, const ShVariant *high) |
| Set a range of values for this variable. | |
Metadata | |
This data is useful for various things, including asset management. | |
| ShVariantPtr | lowBoundVariant () const |
| ShVariantPtr | highBoundVariant () const |
| Obtain an upper bounds on this variable (tuple of same size as this). | |
Protected Attributes | |
| ShVariableNodePtr | m_node |
| The actual variable node we refer to. | |
| ShSwizzle | m_swizzle |
| Swizzling applied to this variable. | |
| bool | m_neg |
| True iff this variable is negated. | |
Friends | |
| SH_DLLEXPORT std::ostream & | operator<< (std::ostream &out, const ShVariable &shVariableToPrint) |
Note: subclasses should not keep any additional data. All data relevant to the node should be stored in m_node. This is due to instances of subclasses of ShVariable being sliced when they get placed in ShStatements.

Sets result to this' variant if possible. Otherwise, if swizzling or negation are required, then makes a copy into result.
