Functions

void java_bytecode_instrument_symbol (symbol_table_baset &symbol_table, symbolt &symbol, const bool throw_runtime_exceptions, message_handlert &message_handler)

Instruments the code attached to symbol with runtime exceptions or corresponding assertions.

void java_bytecode_instrument_uncaught_exceptions (code_blockt &init_code, const symbolt &exc_symbol, const source_locationt &source_location)

Instruments the start function with an assertion that checks whether an exception has escaped the entry point.

Function Documentation

◆ java_bytecode_instrument()

void java_bytecode_instrument ( symbol_table_baset & symbol_table,

const bool throw_runtime_exceptions,

message_handlert & message_handler

)

Instruments all the code in the symbol_table with runtime exceptions or corresponding assertions.

Exceptions are thrown when the throw_runtime_exceptions flag is set. Otherwise, assertions are emitted.

Parameters: symbol_table global symbol table, all of whose code members will be annotated (may gain exception type stubs and similar)

throw_runtime_exceptions flag determining whether we instrument the code with runtime exceptions or with assertions. The former applies if this flag is set to true.

message_handler stream to report status and warnings

Definition at line 594 of file java_bytecode_instrument.cpp.

◆ java_bytecode_instrument_symbol()

void java_bytecode_instrument_symbol ( symbol_table_baset & symbol_table,

symbolt & symbol,

const bool throw_runtime_exceptions,

message_handlert & message_handler

)

Instruments the code attached to symbol with runtime exceptions or corresponding assertions.

Exceptions are thrown when the throw_runtime_exceptions flag is set. Otherwise, assertions are emitted.

Parameters: symbol_table global symbol table (may gain exception type stubs and similar)

symbol the symbol to instrument

throw_runtime_exceptions flag determining whether we instrument the code with runtime exceptions or with assertions. The former applies if this flag is set to true.

message_handler stream to report status and warnings

◆ java_bytecode_instrument_uncaught_exceptions()

void java_bytecode_instrument_uncaught_exceptions ( code_blockt & init_code,

const symbolt & exc_symbol,

const source_locationt & source_location

)

Instruments the start function with an assertion that checks whether an exception has escaped the entry point.

Parameters: init_code the code block to which the assertion is appended

exc_symbol the top-level exception symbol

source_location the source location to attach to the assertion
