Class BooleanValueSegment

java.lang.Object

org.yamcs.parameterarchive.BaseSegment

org.yamcs.parameterarchive.BooleanValueSegment

All Implemented Interfaces:

ValueSegment

public class BooleanValueSegment
extends BaseSegment
implements ValueSegment

Boolean value segment uses a boolean array backed by a long[] to represent the boolean values as a set of bits

Method Summary

Modifier and Type	Method	Description
void	add(Value value)	Add data at the end of the segment.
int	getMaxSerializedSize()
ValueArray	getRange(int posStart, int posStop, boolean ascending)	returns an array containing the values in the range [posStart, posStop) if ascending or [posStop, posStart) if descending
Value	getValue(int index)	returns Value at position index
void	insert(int pos, Value value)	Insert data at position pos.
static BooleanValueSegment	parseFrom(ByteBuffer bb)
int	size()	returns the size of the BitSet storing the values - this will round up to the size of long

BooleanValueSegment

public BooleanValueSegment()

Method Details

insert

public void insert(int pos,
 Value value)

Description copied from interface: ValueSegment

Insert data at position pos. The data at the subsequent positions is shifted to the right.

Specified by:

insert in interface ValueSegment

add

public void add(Value value)

Description copied from interface: ValueSegment

Add data at the end of the segment.

Specified by:

add in interface ValueSegment

writeTo

public void writeTo(ByteBuffer bb)

write the segment to buffer

Specified by:

writeTo in class BaseSegment

Parameters:

bb -

parseFrom

public static BooleanValueSegment parseFrom(ByteBuffer bb)
                                     throws DecodingException

Throws:

DecodingException

getMaxSerializedSize

public int getMaxSerializedSize()

Specified by:

getMaxSerializedSize in class BaseSegment

Returns:

a high approximation for the serialized size in order to allocate a ByteBuffer big enough

getValue

public Value getValue(int index)

Description copied from interface: ValueSegment

returns Value at position index

Specified by:

getValue in interface ValueSegment

Returns:

the value at the index

getRange

public ValueArray getRange(int posStart,
 int posStop,
 boolean ascending)

Description copied from interface: ValueSegment

returns an array containing the values in the range [posStart, posStop) if ascending or [posStop, posStart) if descending

Specified by:

getRange in interface ValueSegment

Returns:

an array containing the values in the specified range

size

public int size()

returns the size of the BitSet storing the values - this will round up to the size of long

Specified by:

size in interface ValueSegment

Specified by:

size in class BaseSegment

toString

public String toString()

Overrides:

toString in class Object
