Member Function Documentation

int DD::Image::Authoring::getIndex

(

Mode

mode

)

const

Gets the choice index of the mode (as in a dropdown)

Parameters

mode	to get the choice index for

Returns

index of the mode or -1 if there isn't one

Authoring::Mode DD::Image::Authoring::getMode

(

int

index

)

const

Gets the mode from the choice index (as in a dropdown)

Parameters

index

the choice number to get the mode for

Returns

the mode it corresponds to for this knob

std::vector< Authoring::Mode > DD::Image::Authoring::getModes

(

)

const

Returns the available authoring mode types if authoring is supported, otherwise an empty list.

void DD::Image::Authoring::setModes

(

const std::vector< Mode > &

modes

)

Sets the available authoring modes. Without setting this, authoring is disabled. This will update the set mode and the default mode if the currently set mode isn't in the list of modes.

References getModeName().

void DD::Image::Authoring::setDefaultMode

(

Mode

defaultMode

)

Sets the mode that will be selected by default - won't set values if the default doesn't exist in the modes

std::vector< std::string > DD::Image::Authoring::getModeNames

(

)

const

Returns the available authoring mode names if authoring is supported, otherwise an empty list.

bool DD::Image::Authoring::setMode

(

Mode

mode

)

Sets the authoring mode from the type. Returns true if successfully set, otherwise false, e.g. if the mode is not a supported authoring mode by the Node (Op).

bool DD::Image::Authoring::setMode

(

int

mode

)

Sets the authoring mode from the integer. Returns true if successfully set, otherwise false, e.g. if the integer cannot be converted to a valid authoring mode.

References getMode(), and setMode().

bool DD::Image::Authoring::setMode

(

const std::string &

name

)

Sets the authoring mode from the name. Returns true if successfully set, otherwise false, e.g. if the string is not a valid authoring mode name.
