buildProgram

public static void buildProgram(Program program,
                                ByteProvider provider,
                                FileBytes fileBytes,
                                MessageLog log,
                                TaskMonitor monitor)
                         throws java.lang.Exception

Builds up a Mach-O Program.

Parameters:

program - The Program to build up.

provider - The ByteProvider that contains the Mach-O's bytes.

fileBytes - Where the Mach-O's bytes came from.

log - The log.

monitor - A cancelable task monitor.
