89 * Class for processing all of the leaf fields of a variable that corresponds
90 * to a program resource.
92 * The leaf fields are all the parts of the variable that the application
93 * could query using \c glGetProgramResourceIndex (or that could be returned
94 * by \c glGetProgramResourceName).
96 * Classes my derive from this class to implement specific functionality.
97 * This class only provides the mechanism to iterate over the leaves. Derived
98 * classes must implement \c ::visit_field and may override \c ::process.
100 class program_resource_visitor
{
103 * Begin processing a variable
105 * Classes that overload this function should call \c ::process from the
106 * base class to start the recursive processing of the variable.
108 * \param var The variable that is to be processed
110 * Calls \c ::visit_field for each leaf of the variable.
113 * When processing a uniform block, this entry should only be used in cases
114 * where the row / column ordering of matrices in the block does not
115 * matter. For example, enumerating the names of members of the block, but
116 * not for determining the offsets of members.

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

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