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

*var

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

142 * The default implementation just calls the other \c visit_field method.
