Public Constructors
public PerfByteArrayMonitor (String name, Units u, Variability v, boolean supported, ByteBuffer bb, int vectorLength)
Constructor to create a ByteArrayMonitor for the byte array instrument represented by the data in the given buffer.
Parameters
| name | the name of the instrumentation object |
|---|---|
| u | the units of measure attribute |
| v | the variability attribute |
| supported | support level indicator |
| bb | the buffer containing the byte array instrument data |
| vectorLength | the length of the vector. |
Public Methods
public byte[] byteArrayValue ()
Get a copy of the elements of the byte array instrument.
Returns
- byte[] - a copy of the current value of the elements of the byte array instrument.
public byte byteAt (int index)
Get the current value of an element of the byte array instrument.
Returns
- byte - a copy of the current value of the element at index index of the byte array instrument.
public int getMaximumLength ()
Get the maximum length of the byte array for this byte array instrument.
Returns
- int - the maximum length of the byte array.
public Object getValue ()
Return an Object that encapsulates this instrumentation object's current data value. The object returned contains a byte[] with a copy of the current elements of the ByteArrayInstrument.
Returns
- Object - a copy of the current value of the elements of the byte array instrument. The return type is guaranteed to be of type byte[].
