close
public void close() throws IOException
- Specified by:
close
in interfaceAutoCloseable
- Specified by:
close
in interfaceCloseable
- Throws:
IOException
-
size
public int size()
Description copied from interface:Indexed
Number of elements in the value set- Specified by:
size
in interfaceIndexed<IndexedInts>
-
get
public IndexedInts get(int index)
Description copied from interface:ColumnarMultiInts
Returns the values at a given row index. The IndexedInts object may potentially be reused, so callers should not keep references to it.- Specified by:
get
in interfaceColumnarMultiInts
- Specified by:
get
in interfaceIndexed<IndexedInts>
-
getUnshared
public IndexedInts getUnshared(int index)
Description copied from interface:ColumnarMultiInts
Returns the values at a given row index. The IndexedInts object will not be reused. This method may be less efficient than plain "get".- Specified by:
getUnshared
in interfaceColumnarMultiInts
-
indexOf
public int indexOf(IndexedInts value)
Description copied from interface:Indexed
Returns the index of "value" in this Indexed object, or a negative number if the value is not present. The negative number is not guaranteed to be any particular number unlessIndexed.isSorted()
returns true, in which case it will be a negative number equal to (-(insertion point) - 1), in the manner of Arrays.binarySearch.- Specified by:
indexOf
in interfaceIndexed<IndexedInts>
- Parameters:
value
- value to search for- Returns:
- index of value, or a negative number (equal to (-(insertion point) - 1) if
Indexed.isSorted()
)
-
iterator
public Iterator<IndexedInts> iterator()
- Specified by:
iterator
in interfaceIterable<IndexedInts>
-
inspectRuntimeShape
public void inspectRuntimeShape(RuntimeShapeInspector inspector)
Description copied from interface:HotLoopCallee
Implementations of this method should callinspector.visit()
with all fields of this class, which meet two conditions: 1. They are used in methods of this class, annotated withCalledFromHotLoop
2. They are either: a. Nullable objects b. Instances of HotLoopCallee c. Objects, which don't always have a specific class in runtime. For example, a field of typeSet
could beHashSet
orTreeSet
in runtime, depending on how this instance (the instance on which inspectRuntimeShape() is called) is configured. d. ByteBuffer or similar objects, where byte order matters e. boolean flags, affecting branch taking f. Arrays of objects, meeting any of conditions a-e.- Specified by:
inspectRuntimeShape
in interfaceHotLoopCallee
