# A function info object specifies the type and other special data for the

# parsing the "cmd_buffer_functions.txt", one for each function in the
# file. These function info objects can be augmented and their values can be
# overridden by adding an object to the table below.
#
# Must match function names specified in "cmd_buffer_functions.txt".
#
# cmd_comment: A comment added to the cmd format.
# type: defines which handler will be used to generate code.
# decoder_func: defines which function to call in the decoder to execute the
# corresponding GL command. If not specified the GL command will
# be called directly.
# gl_test_func: GL function that is expected to be called when testing.
# cmd_args: The arguments to use for the command. This overrides generating
# them based on the GL function arguments.
# gen_cmd: Whether or not this function geneates a command. Default = True.
# data_transfer_methods: Array of methods that are used for transfering the
# pointer data. Possible values: 'immediate', 'shm', 'bucket'.
# The default is 'immediate' if the command has one pointer
# argument, otherwise 'shm'. One command is generated for each
# transfer method. Affects only commands which are not of type
# 'HandWritten', 'GETn' or 'GLcharN'.
# Note: the command arguments that affect this are the final args,
# taking cmd_args override into consideration.
# impl_func: Whether or not to generate the GLES2Implementation part of this
# command.
# impl_decl: Whether or not to generate the GLES2Implementation declaration
# for this command.
# needs_size: If True a data_size field is added to the command.
# count: The number of units per element. For PUTn or PUT types.
# use_count_func: If True the actual data count needs to be computed; the count
# argument specifies the maximum count.
# unit_test: If False no service side unit test will be generated.
# client_test: If False no client side unit test will be generated.
# expectation: If False the unit test will have no expected calls.
# gen_func: Name of function that generates GL resource for corresponding
# bind function.
# states: array of states that get set by this function corresponding to
# the given arguments
# state_flag: name of flag that is set to true when function is called.
# no_gl: no GL function is called.
# valid_args: A dictionary of argument indices to args to use in unit tests
# when they can not be automatically determined.
# pepper_interface: The pepper interface that is used for this extension
# pepper_name: The name of the function as exposed to pepper.
# pepper_args: A string representing the argument list (what would appear in
# C/C++ between the parentheses for the function declaration)
# that the Pepper API expects for this function. Use this only if
# the stable Pepper API differs from the GLES2 argument list.
# invalid_test: False if no invalid test needed.
# shadowed: True = the value is shadowed so no glGetXXX call will be made.
# first_element_only: For PUT types, True if only the first element of an
# array is used and we end up calling the single value
# corresponding function. eg. TexParameteriv -> TexParameteri
# extension: Function is an extension to GL and should not be exposed to
# pepper unless pepper_interface is defined.
# extension_flag: Function is an extension and should be enabled only when
# the corresponding feature info flag is enabled. Implies
# 'extension': True.
