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

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

146 * Method invoked for each leaf of the variable
148 * \param type Type of the field.

151 * \param record_type Type of the record containing the field.
152 * \param last_field Set if \c name is the last field of the structure
153 * containing it. This will always be false for items
154 * not contained in a structure or interface block.
