Member Function Documentation

uint8_t * serialize ( M2MObjectInstanceList  object_instance_list,
uint32_t &  size 
)

Serialises given objects instances that contain resources or multiple resources.

Object instance IDs are also encoded. This method must be used when an operation targets an object with (potential) multiple instances like "GET /1". In that case the generated TLV will contain the following data:

  • ./0
  • ./0/0
  • ./0/1
  • ...
  • ./1
  • ./1/0
  • ./1/1
  • ...
Parameters:
objectsList of object instances.
Returns:
Object instances encoded binary as OMA-TLV
See also:
serializeObjectInstances(List)

uint8_t * serialize ( M2MResourceList  resource_list,
uint32_t &  size 
)

Serialises given resources with no information about the parent object instance.

This method must be used when an operation targets an object instance like "GET /1/0" or a single-instance object like "GET /3//". Resources may have single or multiple instances. The generated TLV will contain the following data as response to "GET /3//":

  • ./0
  • ./1
  • ./2
  • ./6/0 (1st instance of a multiple resource)
  • ./6/1 (2nd instance of a multiple resource)
  • ...
Parameters:
resourcesArray of resources and resource instances.
Returns:
Resources encoded binary as OMA-TLV
See also:
serializeResources(List)
