Method Detail

getVariable

VariableAccess_ifc getVariable(java.lang.String dataPath)

Searches the variable in the container and returns the access to it.

• path[index]: The dataPath can have array access designations "[index]". Than usual an instance of VariableAccessWithIdx is returned, which contains the index and the reference to the variable in the container. If the variable is an array variable and the dataPath does not contains an "[index]", the array variable is returned which implements the VariableAccessArray_ifc usual.
• path.9..5: The dataPath can contain a bit designation as last part. "9..5" means the bits 9 to 5, it is the mask 0x03e, shiftet >>3. That value are presented then. If a bit designation is given, the return instance is an VariableAccessWithBitmask instance.

Parameters:

dataPath - Path.

Returns:

Instance of access control to the variable. The instance may instanceof VariableAccessArray_ifc. Then a cast should be recommended to access the array elements. That is a special case.

setCallbackOnReceivedData

void setCallbackOnReceivedData(java.lang.Runnable callback)

Ensures that the variables will get the actual values, maybe forces communication with any device.
