Constructor Detail

PowerPCDisassembleCommand

public PowerPCDisassembleCommand(AddressSetView startSet,
                                 AddressSetView restrictedSet,
                                 boolean vleMode)

Constructor for PowerPCDisassembleCommand.

Parameters:

startSet - set of addresses to be the start of a disassembly. The Command object will attempt to start a disassembly at each address in this set.

restrictedSet - addresses that can be disassembled. a null set implies no restrictions

vleMode - pass true if the disassembling in PowerISA VLE Mode, otherwise normal disassembly will be performed.

PowerPCDisassembleCommand

public PowerPCDisassembleCommand(Address start,
                                 AddressSetView restrictedSet,
                                 boolean vleMode)

Constructor for PowerPCDisassembleCommand.

Parameters:

start - address to be the start of a disassembly.

restrictedSet - addresses that can be disassembled. a null set implies no restrictions

vleMode - pass true if the disassembling in PowerISA VLE Mode, otherwise normal disassembly will be performed.

Method Detail

getName

public java.lang.String getName()

Description copied from interface: Command

Returns the name of this command.

Specified by:

getName in interface Command

Overrides:

getName in class BackgroundCommand

Returns:

the name of this command

setSeedContext

public void setSeedContext(DisassemblerContextImpl seedContext)

Description copied from class: DisassembleCommand

Allows the disassembler context to be seeded for the various disassembly start points which may be encountered using the future flow state of the specified seedContext. Any initial context set via the DisassembleCommand.setInitialContext(RegisterValue) method will take precedence when combined with any seed values. The seedContext should remain unchanged while disassembler command is actively running.

Overrides:

setSeedContext in class DisassembleCommand

Parameters:

seedContext - seed context or null

setInitialContext

public void setInitialContext(RegisterValue initialContextValue)

Description copied from class: DisassembleCommand

Allows a specified initial context to be used at all start points. This value will take precedence when combined with any individual seed context values specified by the DisassembleCommand.setSeedContext(DisassemblerContextImpl) method. The defaultSeedContext should remain unchanged while disassembler command is actively running.

Overrides:

setInitialContext in class DisassembleCommand

Parameters:

initialContextValue - the initial context value to set or null to clear it

applyTo

public boolean applyTo(DomainObject obj,
                       TaskMonitor monitor)

Description copied from class: BackgroundCommand

Method called when this command is to apply changes to the given domain object. A monitor is provided to display status information about the command as it executes in the background.

Overrides:

applyTo in class DisassembleCommand

Parameters:

obj - domain object that will be affected by the command

monitor - monitor to show progress of the command

Returns:

true if the command applied successfully
