Detailed Documentation¶

If operation.

Construction¶

If(const Output<Node>& execution_condition)

Constructs If with condition.

Parameters:

execution_condition

condition node.

Methods¶

const std::shared_ptr<Model>& get_then_body() const

gets then_body as ov::Model.

Returns:

then_body as ov::Model.

const std::shared_ptr<Model>& get_else_body() const

gets else_body as ov::Model.

Returns:

else_body as ov::Model.

void set_then_body(const std::shared_ptr<Model>& body)

sets new ov::Model as new then_body.

Parameters:

body	new body for ‘then’ branch.

void set_else_body(const std::shared_ptr<Model>& body)

sets new ov::Model as new else_body.

Parameters:

body	new body for ‘else’ branch.

void set_input(
    const Output<Node>& value,
    const std::shared_ptr<v0::Parameter>& then_parameter,
    const std::shared_ptr<v0::Parameter>& else_parameter
    )

sets new input to the operation associated with parameters of each sub-graphs

Parameters:

value	input to operation
then_parameter	parameter for then_body or nullptr
else_parameter	parameter for else_body or nullpt

Output<Node> set_output(
    const std::shared_ptr<v0::Result>& then_result,
    const std::shared_ptr<v0::Result>& else_result
    )

sets new output from the operation associated with results of each sub-graphs

Parameters:

then_result	result from then_body
else_parameter	result from else_body

Returns:

output from operation

virtual void validate_and_infer_types()

Verifies that attributes and inputs are consistent and computes output shapes and element types. Must be implemented by concrete child classes so that it can be run any number of times.

Throws if the node is invalid.
