References contains(), and openmsx::MSXDevice::getName().

◆ getDevices()

inline

Definition at line 19 of file MSXMultiIODevice.hh.

◆ getName()

std::string openmsx::MSXMultiIODevice::getName ( ) const
overridevirtual

Returns a human-readable name for this device.

Default implementation is normally ok.

Reimplemented from openmsx::MSXDevice.

Definition at line 34 of file MSXMultiIODevice.cc.

References getNameList(), and openmsx::TclObject::getString().

◆ getNameList()

void openmsx::MSXMultiIODevice::getNameList ( TclObject result) const
overridevirtual

Returns list of name(s) of this device.

This is normally the same as getName() (but formatted as a Tcl list) except for multi-{mem,io}-devices.

Reimplemented from openmsx::MSXDevice.

Definition at line 40 of file MSXMultiIODevice.cc.

References openmsx::TclObject::addListElement().

Referenced by getName().

◆ peekIO()

byte openmsx::MSXMultiIODevice::peekIO ( word  port,
EmuTime::param  time 
) const
overridevirtual

Read a byte from a given IO port.

Reading via this method has no side effects (doesn't change the device status). If safe reading is not possible this method returns 0xFF. This method is not used by the emulation. It can however be used by a debugger. The default implementation just returns 0xFF.

Reimplemented from openmsx::MSXDevice.

Definition at line 62 of file MSXMultiIODevice.cc.

◆ readIO()

byte openmsx::MSXMultiIODevice::readIO ( word  port,
EmuTime::param  time 
)
overridevirtual

Read a byte from an IO port at a certain time from this device.

The default implementation returns 255.

Reimplemented from openmsx::MSXDevice.

Definition at line 50 of file MSXMultiIODevice.cc.

◆ removeDevice()

void openmsx::MSXMultiIODevice::removeDevice ( MSXDevice device)

Definition at line 29 of file MSXMultiIODevice.cc.

References rfind_unguarded().

◆ writeIO()

void openmsx::MSXMultiIODevice::writeIO ( word  port,
byte  value,
EmuTime::param  time 
)
overridevirtual

Write a byte to a given IO port at a certain time to this device.

The default implementation ignores the write (does nothing)

Reimplemented from openmsx::MSXDevice.
