Method Summary

Modifier and Type	Method and Description
boolean	equals(GpioFlags flags) Are those two flags equal ?
boolean	equals(Object o)
boolean	isActiveLow() Are those flags describing active low line(s) ?
boolean	isInput() Are those flags describing digital input(s) ?
boolean	isOpenDrain() Are those flags describing open drain line(s) ?
boolean	isOpenSource() Are those flags describing open source line(s) ?
boolean	isOutput() Are those flags describing a digital output(s) ?
GpioFlags	setActiveLow(boolean isActiveLow) Sets or not to active low, meaning the kernel will inverse values.
GpioFlags	setInput() Sets as a digital input.
GpioFlags	setOpenDrain(boolean isOpenDrain) Sets or not to open drain.
GpioFlags	setOpenSource(boolean isOpenSource) Sets or not to open source.

Constructor Detail

GpioFlags

public GpioFlags()

Basic constructor.

Method Detail

setInput

public GpioFlags setInput()

Sets as a digital input.

Returns:

This GpioFlags instance.

setOutput

public GpioFlags setOutput()

Sets as a digital output.

Returns:

This GpioFlags instance.

setActiveLow

public GpioFlags setActiveLow(boolean isActiveLow)

Sets or not to active low, meaning the kernel will inverse values.

A low signal will be logical high and vice-versa.

Parameters:

isActiveLow - Should be active low ?

Returns:

This GpioFlags instance.

setOpenDrain

public GpioFlags setOpenDrain(boolean isOpenDrain)

Sets or not to open drain.

For outputs, lines can be driven low but not high. When driven high, the lines will actually be undefined and acting as inputs.

Parameters:

isOpenDrain - Should be open drain ?

Returns:

This GpioFlags instance.

setOpenSource

public GpioFlags setOpenSource(boolean isOpenSource)

Sets or not to open source.

For outputs, lines can be driven high but no low. When driven low, the lines will actually be undefined and acting as inputs.

Parameters:

isOpenSource - Should be open source ?

Returns:

This GpioFlags instance.

isInput

public boolean isInput()

Are those flags describing digital input(s) ?

Returns:

A boolean.

isOutput

public boolean isOutput()

Are those flags describing a digital output(s) ?

Returns:

A boolean.

isActiveLow

public boolean isActiveLow()

Are those flags describing active low line(s) ?

Returns:

A boolean.

isOpenDrain

public boolean isOpenDrain()

Are those flags describing open drain line(s) ?

Returns:

A boolean.

isOpenSource

public boolean isOpenSource()

Are those flags describing open source line(s) ?

Returns:

A boolean.

equals

public boolean equals(GpioFlags flags)

Are those two flags equal ?

Parameters:

flags - Flags for comparison.

Returns:

A boolean.

equals

public boolean equals(Object o)

Overrides:
