For store/restore custom data blocks this is PIMemoryBlock class. Stream operators of this class simply store/restore data block to/from stream:

float a_read[10], a_write[10];
for (int i = 0; i < 10; ++i) {
    a_read [i] = 0.f;
    a_write[i] = i / 10.f;
}
 
PIByteArray data;
data << PIMemoryBlock(a_write, 10 * sizeof(float));
 
piCout << data.toHex();
 
data >> PIMemoryBlock(a_read, 10 * sizeof(float));
for (int i = 0; i < 10; ++i)
    piCout << a_read[i];

Result:
