## natural_vector_size() [1/2]

int Halide::Internal::GeneratorBase::natural_vector_size | ( | Halide::Type | t | ) | const

inline

Given a data type, return an estimate of the "natural" vector size for that data type when compiling for the current target.

## natural_vector_size() [2/2]

template<typename data_t>

int Halide::Internal::GeneratorBase::natural_vector_size | ( |  | ) | const

inline

## set_inputs()

template<typename... Args>

void Halide::Internal::GeneratorBase::set_inputs | ( | const Args &... | args | ) |

inline

set_inputs is a variadic wrapper around set_inputs_vector, which makes usage much simpler in many cases, as it constructs the relevant entries for the vector for you, which is often a bit unintuitive at present.

The arguments are passed in Input<>-declaration-order, and the types must be compatible. Array inputs are passed as std::vector<> of the relevant type.

Note: at present, scalar input types must match exactly, i.e., for Input<uint8_t>, you must pass an argument that is actually uint8_t; an argument that is int-that-will-fit-in-uint8 will assert-fail at Halide compile time.

## context()

GeneratorContext Halide::Internal::GeneratorBase::context | ( |  | ) | const

override virtual

Return the Target and autoscheduler info that this Generator was created with.

Always legal to call on any AbstractGenerator instance, regardless of what other methods have been called. (All AbstractGenerator instances are expected to be created with immutable values for these, which can't be changed for a given instance after creation. Note that Generator<> based subclasses can customize Target somewhat via init_from_context(); see Generator.h for more info.)

## arginfos()

std::vector< ArgInfo > Halide::Internal::GeneratorBase::arginfos | ( |  | ) |

override virtual

Return a list of all the ArgInfos for this generator.

The list will be in the order that the input and outputs are declared (possibly interleaved). Any inputs or outputs added by a configure() method will be in the list, at the end, in the order added. All input and output names will be unique within a given Generator instance.

CALL-AFTER: configure() CALL-BEFORE: any

Implements Halide::Internal::AbstractGenerator.

## allow_out_of_order_inputs_and_outputs()

bool Halide::Internal::GeneratorBase::allow_out_of_order_inputs_and_outputs | ( |  | ) | const

override virtual

By default, a Generator must declare all Inputs before all Outputs.

In some unusual situations (e.g. metaprogramming situations), it's desirable to allow them to be declared out-of-order and put the onus of a non-obvious call order on the coder; a Generator may override this to return 'true' to allow this behavior.

Implements Halide::Internal::AbstractGenerator.

## set_generatorparam_value() [1/2]

void Halide::Internal::GeneratorBase::set_generatorparam_value | ( | const std::string & | name,
|  | const std::string & | value )

override virtual

Set the value for a specific GeneratorParam for an AbstractGenerator instance.

Names that aren't known generator names should assert-fail.

Values that can't be parsed for the specific GeneratorParam (e.g. passing "foo" where an integer is expected) should assert-fail at some point (either immediately, or when build_pipeline() is called)

This can be called multiple times, but only prior to build_pipeline().

## set_generatorparam_value() [2/2]

## input_parameter()

std::vector< Parameter > Halide::Internal::GeneratorBase::input_parameter | ( | const std::string & | name | ) |

References name().

## output_func()

std::vector< Func > Halide::Internal::GeneratorBase::output_func | ( | const std::string & | name | ) |

override virtual

Given the name of an output, return the Func(s) for that output.

Most outputs will have exactly one, but outputs that are declared as arrays will have multiple.

Note that outputs with Tuple values are still just a single Func, though they do get realized as multiple Buffers.

Must be called after build_pipeline(), since the output Funcs will be undefined prior to that.

## bind_input() [1/3]

void Halide::Internal::GeneratorBase::bind_input | ( | const std::string & | name,
|  | const std::vector< Parameter > & | v )

override virtual

Rebind a specified Input to refer to the given piece of IR, replacing the default ImageParam / Param in place for that Input.

Basic type-checking is done to ensure that inputs are still sane (e.g. types, dimensions, etc must match expectations).

CALL-AFTER: set_generatorparam_value CALL-BEFORE: build_pipeline

Implements Halide::Internal::AbstractGenerator.

## emit_cpp_stub()

bool Halide::Internal::GeneratorBase::emit_cpp_stub | ( | const std::string & | stub_file_path | ) |

override virtual

Emit a Generator Stub (.stub.h) file to the given path.

Not all Generators support this.

If you call this method, you should not call any other AbstractGenerator methods on this instance, before or after this call.

If the Generator is capable of emitting a Stub, do so and return true. (Errors during stub emission should assert-fail rather than returning false.)

If the Generator is not capable of emitting a Stub, do nothing and return false.

CALL-AFTER: none CALL-BEFORE: none

Implements Halide::Internal::AbstractGenerator.

## emit_hlpipe()

bool Halide::Internal::GeneratorBase::emit_hlpipe | ( | const std::string & | hlpipe_file_path | ) |

override virtual

Emit a Serialized Halide Pipeline (.hlpipe) file to the given path.

Not all Generators support this.

If you call this method, you should not call any other AbstractGenerator methods on this instance, before or after this call.

If the Generator is capable of emitting an hlpipe, do so and return true. (Errors during hlpipe emission should assert-fail rather than returning false.)

If the Generator is not capable of emitting an hlpipe, do nothing and return false.

CALL-AFTER: none CALL-BEFORE: none
