Class Internal.Cell

java.lang.Object

net.opentsdb.core.Internal.Cell

All Implemented Interfaces:

Comparable<Internal.Cell>

Enclosing class:

Internal

public static final class Internal.Cell
extends Object
implements Comparable<Internal.Cell>

Represents a single data point in a row. Compacted columns may not be stored in a cell.

This is simply a glorified pair of (qualifier, value) that's comparable. Only the qualifier is used to make comparisons.

Since:

2.0

             byte[] value)

Constructor that sets the cell

Parameters:

qualifier - Qualifier to store

value - Value to store

Method Detail

compareTo

public int compareTo(Internal.Cell other)

Compares the qualifiers of two cells

Specified by:

compareTo in interface Comparable<Internal.Cell>

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

Returns:

a hash code based on the qualifier bytes

toString

public String toString()

Prints the raw data of the qualifier and value

Overrides:

toString in class Object

qualifier

the qualifier byte array

value

public byte[] value()

Returns:

the value byte array

parseValue

public Number parseValue()

Returns the value of the cell as a Number for passing to a StringBuffer

Returns:

The numeric value of the cell

Throws:

IllegalDataException - if the value is invalid

timestamp

public long timestamp(long base_time)

Returns the Unix epoch timestamp in milliseconds

Parameters:

base_time - Row key base time to add the offset to

Returns:

Unix epoch timestamp in milliseconds

absoluteTimestamp

public long absoluteTimestamp(long base_time)

Returns the timestamp as stored in HBase for the cell, i.e. in seconds or milliseconds

Parameters:

base_time - Row key base time to add the offset to

Returns:

Unix epoch timestamp

isInteger

public boolean isInteger()

Returns:

Whether or not the value is an integer
