Detailed Description

Class encoding a data type.

This is a basic Open Inventor type that is used for representing a data type, for example unsigned int32, and some information about that type, for example is it signed or not. It is used by classes handling user buffers such as SoMemoryObject, SoSFArray2D, SoSFArray3D, SoSFImage and also SoDataSet.

(

void

)

const [inline]

Returns size in bytes of the type.

SbString SbDataType::getString

(

)

const

Returns the type as a string, e.g.

"FLOAT". See also getType().
