braket.default_simulator.openqasm.parser.braket_pragmas module

class braket.default_simulator.openqasm.parser.braket_pragmas.BraketPragmaNodeVisitor(qubit_table: QubitTable)[source]

Bases: BraketPragmasParserVisitor

This is a visitor for the BraketPragmas grammar. Consumes a braketPragmas AST and converts to relevant python objects for use by the Interpreter

braket.default_simulator.openqasm.parser.braket_pragmas.parse_braket_pragma(pragma_body: str, qubit_table: QubitTable)[source]

Parse braket pragma and return relevant information.

Pragma types include:

  • result types

  • custom unitary operations
