Method Details

encodeAndGet

public ByteBuffer encodeAndGet(int[] input)

Encode the input array into the internal buffer and return it.

Parameters:

input - the array to encode

Returns:

a reference to the internal byte buffer

maybeGetResizedBuffer

@NotNull
public static @NotNull ByteBuffer maybeGetResizedBuffer(@Nullable
 @org.jetbrains.annotations.Nullable int[] input,
 @Nullable
 @Nullable ByteBuffer origBuffer)

Inspect the input buffer. If it is large enough to encode input, clear and return it, otherwise allocate a new buffer with an appropriate capacity and return that.

Parameters:

input - the input to encode

origBuffer - the original buffer to maybe resize.

Returns:

a properly sized byte buffer to encode input.

encodeInto

public static void encodeInto(@Nullable
 @org.jetbrains.annotations.Nullable int[] input,
 @NotNull
 @NotNull ByteBuffer byteBuffer)

Encode the input values to the specified buffer.

Parameters:

input - the input, may be null.

byteBuffer - the buffer to encode into

decode

@Nullable
public @org.jetbrains.annotations.Nullable int[] decode(@NotNull
 @NotNull ByteBuffer byteBuffer)

Decode a int array from the input ByteBuffer

Specified by:

decode in interface io.deephaven.util.codec.ObjectDecoder<int[]>

Parameters:

byteBuffer - the buffer containing the encoded int array

Returns:

the decoded int array

decodeStatic

@Nullable
public static @org.jetbrains.annotations.Nullable int[] decodeStatic(@Nullable
 @Nullable ByteBuffer byteBuffer)

encode

@NotNull
public @org.jetbrains.annotations.NotNull byte[] encode(@Nullable
 @org.jetbrains.annotations.Nullable int[] input)

Specified by:

encode in interface io.deephaven.util.codec.ObjectCodec<int[]>

isNullable

public boolean isNullable()

Specified by:

isNullable in interface io.deephaven.util.codec.ObjectCodec<int[]>

getPrecision

public int getPrecision()

Specified by:

getPrecision in interface io.deephaven.util.codec.ObjectCodec<int[]>

getScale

public int getScale()

Specified by:

getScale in interface io.deephaven.util.codec.ObjectCodec<int[]>

decode

@Nullable
public @org.jetbrains.annotations.Nullable int[] decode(@NotNull
 @org.jetbrains.annotations.NotNull byte[] input,
 int offset,
 int length)

Specified by:

decode in interface io.deephaven.util.codec.ObjectDecoder<int[]>

expectedObjectWidth

public int expectedObjectWidth()

Specified by:

expectedObjectWidth in interface io.deephaven.util.codec.ObjectDecoder<int[]>
