Class ImmutableCharArraySource

java.lang.Object

com.illumon.iris.db.v2.sources.AbstractColumnSource<Character>

com.illumon.iris.db.v2.sources.immutable.ImmutableCharArraySource

All Implemented Interfaces:

ChunkSource<Attributes.Values>, ChunkSource.WithPrev<Attributes.Values>, DefaultChunkSource<Attributes.Values>, DefaultChunkSource.WithPrev<Attributes.Values>, FillContextMaker, GetContextMaker, ColumnSource<Character>, ColumnSourceGetDefaults.ForChar, ElementSource<Character>, ImmutableColumnSource<Character>, ImmutableColumnSourceGetDefaults.ForChar, Releasable, TupleExporter<Character>, TupleSource<Character>, Serializable

public class ImmutableCharArraySource
extends AbstractColumnSource<Character>
implements ImmutableColumnSourceGetDefaults.ForChar

Simple array source for Immutable Char.

The ImmutableC-harArraySource is replicated to all other types with com.illumon.iris.db.v2.sources.Replicate. (C-har is deliberately spelled that way in order to prevent Replicate from altering this very comment).

Constructor Details

ImmutableCharArraySource

public ImmutableCharArraySource(char[] source)

Method Details

getChar

public char getChar(long index)

Description copied from interface: ElementSource

Get the value at the index as a char.

Specified by:

getChar in interface ElementSource<Character>

Parameters:

index - the location in index space to get the value from.

Returns:

the char at the index, null values are represented by QueryConstants.NULL_CHAR

get

public Character get(long index)

Description copied from interface: ElementSource

Get the value from the source. This may return boxed values for basic types.

Specified by:

get in interface ColumnSourceGetDefaults.ForChar

Specified by:

get in interface ElementSource<Character>

Parameters:

index - the location in index space to get the value from.

Returns:

the value at the index, potentially null.

isImmutable

public boolean isImmutable()

Description copied from interface: ColumnSource

Determine if this column source is immutable, meaning that the values at a given index key never change.

Specified by:

isImmutable in interface ColumnSource<Character>

Specified by:

isImmutable in interface ImmutableColumnSource<Character>

Returns:

true if the values at a given index of the column source never change, false otherwise
