	int firstIndex,
	int numberOfBits,
	int value
)

public void SetGroupValue(
	int firstIndex,
	int numberOfBits,
	int value
)

Public Sub SetGroupValue ( 
	firstIndex As Integer,
	numberOfBits As Integer,
	value As Integer
)

Public Sub SetGroupValue (

public:
void SetGroupValue(
	int firstIndex, 
	int numberOfBits, 
	int value
)

public:
void SetGroupValue(
	int firstIndex, 
	int numberOfBits, 
	int value
)

Parameters

firstIndex: Type: System Int32
The first output line.

numberOfBits: Type: System Int32
The number of lines to write.

value: Type: System Int32

Exceptions

Exception	Condition
CogCollectionInvalidIndexException	firstIndex is < 0 or >= Count.
ArgumentException	numberOfBits is < 1 or > 32.

Remarks

Reads or writes a group of up to 32 output line values as a binary number.

The first output line, specified by firstIndex has a binary value of 1. The last output line, specified by firstIndex+numberOfBits-1, has a binary value of 2^(numberOfBits-1).
