72 * Class for processing all of the leaf fields of a variable that corresponds
73 * to a program resource.
75 * The leaf fields are all the parts of the variable that the application
76 * could query using \c glGetProgramResourceIndex (or that could be returned
77 * by \c glGetProgramResourceName).
79 * Classes my derive from this class to implement specific functionality.
80 * This class only provides the mechanism to iterate over the leaves. Derived
81 * classes must implement \c ::visit_field and may override \c ::process.
83 class program_resource_visitor {
86 * Begin processing a variable
88 * Classes that overload this function should call \c ::process from the
89 * base class to start the recursive processing of the variable.
91 * \param var The variable that is to be processed
93 * Calls \c ::visit_field for each leaf of the variable.
96 * When processing a uniform block, this entry should only be used in cases
97 * where the row / column ordering of matrices in the block does not
98 * matter. For example, enumerating the names of members of the block, but
99 * not for determining the offsets of members.
101 void process(ir_variable *var);
104 * Begin processing a variable of a structured type.
106 * This flavor of \c process should be used to handle structured types
107 * (i.e., structures, interfaces, or arrays there of) that need special
108 * name handling. A common usage is to handle cases where the block name
109 * (instead of the instance name) is used for an interface block.
111 * \param type Type that is to be processed, associated with \c name
112 * \param name Base name of the structured variable being processed
115 * \c type must be \c GLSL_TYPE_RECORD, \c GLSL_TYPE_INTERFACE, or an array
118 void process(const glsl_type *type, const char *name);
122 * Method invoked for each leaf of the variable
124 * \param type Type of the field.
125 * \param name Fully qualified name of the field.
126 * \param row_major For a matrix type, is it stored row-major.
