OpenGL.arrays.formathandler

Base class for the various Python data-format storage type APIs
Data-type handlers are specified using OpenGL.plugins module

Classes

class FormatHandler( object ):
Abstract class describing the handler interface
Each data-type handler is responsible for providing a number of methods which allow it to manipulate (and create) instances of the data-type it represents.
arraySize( self , value , typeCode = None )
Given a data-value, calculate dimensions for the array
arrayToGLType( self , value )
Given a value, guess OpenGL type of the corresponding pointer
asArray( self , value , typeCode = None )
Given a value, convert to array representation
dataPointer( self , value )
return long for pointer value
dimensions( self , value , typeCode = None )
Determine dimensions of the passed array value (if possible)
from_param( self , value , typeCode = None )
Convert to a ctypes pointer value
loadAll( cls )
Load all OpenGL.plugins-registered FormatHandler classes
loadPlugin( cls , entrypoint )
Load a single entry-point via plugins module
register( self , types = None )
Register this class as handler for given set of types
registerReturn( self )
Register this handler as the default return-type handler
typeLookup( cls , type )
Lookup handler by data-type
unitSize( self , value , typeCode = None )
Determine unit size of an array (if possible)
