95 * Class for processing all of the leaf fields of a variable that corresponds
96 * to a program resource.
98 * The leaf fields are all the parts of the variable that the application
99 * could query using \c glGetProgramResourceIndex (or that could be returned
100 * by \c glGetProgramResourceName).
102 * Classes my derive from this class to implement specific functionality.
103 * This class only provides the mechanism to iterate over the leaves. Derived
104 * classes must implement \c ::visit_field and may override \c ::process.
106 class program_resource_visitor

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

129 * This flavor of \c process should be used to handle structured types
130 * (i.e., structures, interfaces, or arrays there of) that need special
131 * name handling. A common usage is to handle cases where the block name
132 * (instead of the instance name) is used for an interface block.
134 * \param type Type that is to be processed, associated with \c name
135 * \param name Base name of the structured variable being processed
138 * \c type must be \c GLSL_TYPE_RECORD, \c GLSL_TYPE_INTERFACE, or an array

151 * \param last_field Set if \c name is the last field of the structure
152 * containing it. This will always be false for items
153 * not contained in a structure or interface block.
155 * The default implementation just calls the other \c visit_field method.
