dataWritten

public boolean dataWritten(PcodeTraceDataAccess acc,
 AddressSet written,
 PcodeThread<?> thread,
 PcodeExecutorStatePiece<byte[],byte[]> piece,
 Address address,
 int length,
 byte[] value)

Description copied from interface: TraceEmulationIntegration.PieceHandler

Data was written (concrete addressing).

Parameters:

acc - the trace access shim for the relevant state (shared or local)

written - the TraceEmulationIntegration.Writer's current log of written addresses (mutable). Typically, this is not accessed but rather passed to delegate methods.

thread - the thread, if applicable. This is null if either the state being accessed is the emulator's shared state, or if the state is bound to a plain PcodeExecutor.

piece - the state piece being handled

address - the start address of the write

length - the size in bytes of the write

value - the value written

Returns:

true to prevent the TraceEmulationIntegration.Writer from updating its log.
