Data is an in-built struct that allows to allocate a certain amount of memory to be used and accessed as an array.
It is possible to loop around the entry of a Data with either a for loop or the loop construct.
params:
numOfPhasors {1, 1, 100}
struct Phasor:
phase
init:
data = Data(10) # 10 float elements: Data() defaults to Data[float]()
data2 = Data[float](10) # 10 float elements
data3 = Data[int](10) # 10 int elements
data4 = Data[Data[float]](10) # 10 Data[float] elements
loop data4: # loop around all elements and initialize Datas
_ = Data(10)
data5 = Data[Phasor](numOfPhasors) # dynamic count according to value of param 'numOfPhasors'
for phasor in data5: # loop around all elements and initialize Phasors
phasor = Phasor()
data6 = Data(10, 2) # 20 total elements: 10 float elements per channel
print data[0] # single channel access
print data6[0, 0] # multichannel access: [chan, index]
Data can store any user defined struct. If the entries are not explicitly initialized, Omni will do it for you at the end of the init block using the default constructor of the specific struct. Furthermore, if you try to access a non-initialized field, Omni will initialize it at the moment of access:
struct Something:
data Data
init:
a = Data[Something](10)
#Will initialize a[1] to Something()
print a[1].data[0]
#Will initialize a[9] to Something(). a[1000] is out of bounds, so it returns the last entry, which is a[9]
#data[1000] is also out bounds, so it will return 0
print a[1000].data[1000]
#a[1] is already initialized, will not re-initialize it and print warning
a[1] = Something()
#All the remaining entries [0, 2, 3, 4, 5, 6, 7, 8] will be initialized here
