Member Function Documentation

setParams()

def tiovx.node.Node.setParams (   self,   num_in,   num_out,   param_type_args  )

inherited

Specify number of input/output parameters and data object type for each.

Assumes input parameters are followed by output parameters. It is recommended user kernels follow this convention.

Parameters

num_in	[in] Number of inputs
num_out	[in] Number of outputs
param_type_args	[in] Variable number of args list of type tiovx.enums.Type to specify data object types. Number of arguments MUST match num_in+num_out

setTarget()

def tiovx.node.Node.setTarget (   self,   target  )

inherited

Specify target on which to run this node.

Parameters

target

[in] Object of type tiovx.enums.Target

Definition at line 339 of file node.py.

setKernelEnumName()

def tiovx.node.Node.setKernelEnumName (   self,   kernel_enum_name  )

inherited

Specify kernel enum name to use.

Use "VX_USER_KERNEL" as 'kernel_enum_name' for custom/user kernels

Parameters

kernel_enum_name

[in] Type string.
