Method Details

getData

public int[] getData()

Description copied from interface: EncodedData

Access to the underlying array of information.

Specified by:

getData in interface EncodedData<int[]>

Specified by:

getData in interface IntArray

Returns:

an int[], double[], byte[], or String[]

length

public int length()

Description copied from interface: EncodedData

The number of elements in the wrapped array.

Specified by:

length in interface EncodedData<int[]>

Specified by:

length in interface IntArray

Returns:

results of array.length

toByteArray

public byte[] toByteArray()

Description copied from interface: NumberArray

Converts this number array to its binary representation.

Specified by:

toByteArray in interface NumberArray<int[]>

Returns:

a byte[]

getNumberOfBytes

public int getNumberOfBytes()

Description copied from interface: NumberArray

The number of bytes used in this representation to describe a single value (e.g. 1 for Int8Array and up to 8 for Float64Array).

Specified by:

getNumberOfBytes in interface NumberArray<int[]>

Returns:

a number between 1 and 4

getType

public int getType()

Description copied from interface: NumberArray

Report the type of this number array.

• 1 for Int8Array
• 2 for Int16Array
• 3 for Int32Array
• 4 for Uint8Array
• 5 for Uint16Array
• 6 for Uint32Array
• 32 for Float32Array
• 33 for Float64Array

Specified by:

getType in interface NumberArray<int[]>

Returns:

1, 2, 3, 4, 5, 6, 32, 33

toString

public String toString()

Overrides:

toString in class Object

encode

public IntArray encode(IntegerPackingEncoding encoding)

encode

public Int32Array encode(DeltaEncoding<Int32Array> encoding)

Specified by:

encode in interface SignedIntArray<Int32Array>

encode

public ByteArray encode()

Description copied from interface: NumberArray

Encode this array of numbers directly as binary data (useful for single values that won't benefit from more elaborate encoding chains).

Specified by:

encode in interface NumberArray<int[]>

Returns:

a ByteArray with a single encoding step

decode

public Int32Array decode(DeltaEncoding<Int32Array> encoding)

Specified by:

decode in interface SignedIntArray<Int32Array>

decode

public FloatArray decode(FixedPointEncoding encoding)

decode

public IntArray decode(RunLengthEncoding encoding)

getEncoding

public Deque<Encoding<?,?>> getEncoding()

Description copied from interface: EncodedData

All encodings registered for this piece of EncodedData. May be empty. May contain only partial data: e.g. adding a ByteArrayEncoding to the list will request encoding by ByteArrayCodec, this method call will subsequently fill all fields of the requested Encoding to allow for decoding.

Specified by:

getEncoding in interface EncodedData<D>

Returns:

all associated Encoding instances

setEncoding

public void setEncoding(Deque<Encoding<?,?>> encoding)

Description copied from interface: EncodedData

Replace this encoding chain with a different one.

Specified by:

setEncoding in interface EncodedData<D>

Parameters:

encoding - the new encoding chain for this instance

hasNextDecodingStep

public boolean hasNextDecodingStep()

Description copied from interface: EncodedData

Convenience method to state whether the List returned by EncodedData.getEncoding() is not empty.

Specified by:

hasNextDecodingStep in interface EncodedData<D>

Returns:

true if encoding steps are registered and need to be resolved to access decoded data
