Method Details

getInstance

public static DataChunkFactory getInstance()

Gets the singleton instance of this class.

create

public DataChunk create(Object data,
 boolean isUnsigned,
 Object missingValue,
 PackingScheme packing)

Creates a new initialized data chunk.

Parameters:

data - the primitive array of data values to be used in the chunk.

isUnsigned - the flag to indicate if the integer primitive values are actually unsigned values packed into a signed primitive (eg: byte value in the range [0..255] packaged as a signed byte in the range [-128..127]).

missingValue - the missing value used as a marker for invalid data, or null for none.

packing - the packing scheme for floating point data values packed as integer values in the chunk, or null for none.

Returns:

the data chunk wrapping the primitive array.

create

public <T extends Number> DataChunk create(Class<T> primitiveType,
 int values,
 boolean isUnsigned,
 Object missingValue,
 PackingScheme packing,
 ScalingScheme scaling)

Creates a new uninitialized data chunk.

Parameters:

primitiveType - the primitive data type for the chunk.

values - the number of values in the data chunk.

isUnsigned - the flag to indicate if the integer primitive values are actually unsigned values packed into a signed primitive (eg: byte value in the range [0..255] packaged as a signed byte in the range [-128..127]).

missingValue - the missing value used as a marker for invalid data, or null for none.

packing - the packing scheme for floating point data values packed as integer values in the chunk, or null for none.

scaling - the scaling scheme for floating point data values or null for none. Either packing or scaling may be specified but not both.

Returns:

the data chunk wrapping the primitive array.

3.6.1
