105 * to a program resource.
107 * The leaf fields are all the parts of the variable that the application
108 * could query using \c glGetProgramResourceIndex (or that could be returned
109 * by \c glGetProgramResourceName).
111 * Classes my derive from this class to implement specific functionality.
112 * This class only provides the mechanism to iterate over the leaves. Derived
113 * classes must implement \c ::visit_field and may override \c ::process.

118 * Begin processing a variable
120 * Classes that overload this function should call \c ::process from the
121 * base class to start the recursive processing of the variable.
123 * \param var The variable that is to be processed
125 * Calls \c ::visit_field for each leaf of the variable.
128 * When processing a uniform block, this entry should only be used in cases
129 * where the row / column ordering of matrices in the block does not
130 * matter. For example, enumerating the names of members of the block, but
131 * not for determining the offsets of members.

139 * (i.e., structures, interfaces, or arrays there of) that need special
140 * name handling. A common usage is to handle cases where the block name
141 * (instead of the instance name) is used for an interface block.
143 * \param type Type that is to be processed, associated with \c name
144 * \param name Base name of the structured variable being processed
147 * \c type must be \c GLSL_TYPE_RECORD, \c GLSL_TYPE_INTERFACE, or an array

161 * \param last_field Set if \c name is the last field of the structure
162 * containing it. This will always be false for items
163 * not contained in a structure or interface block.
