 *
 * #GArrowArrayStatistics is a class for statistics of an array.
 *
 * #GArrowArray is a base class for all array classes such as
 * #GArrowBooleanArray.
 *
 * All array classes are immutable. You need to use binary data or
 * array builder to create a new array except #GArrowNullArray. If you
 * have binary data that uses Arrow format data, you can create a new
 * array with the binary data as #GArrowBuffer object. If you don't
 * have binary data, you can use array builder class such as
 * #GArrowBooleanArrayBuilder that creates Arrow format data
 * internally and a new array from the data.
 *
 * #GArrowNullArray is a class for null array. It can store zero or
 * more null values. You need to specify an array length to create a
 * new array.
 *
 * #GArrowBooleanArray is a class for boolean array. It can store zero
 * or more boolean data. If you don't have Arrow format data, you need
 * to use #GArrowBooleanArrayBuilder to create a new array.
 *
 * #GArrowInt8Array is a class for 8-bit integer array. It can store
 * zero or more 8-bit integer data. If you don't have Arrow format
 * data, you need to use #GArrowInt8ArrayBuilder to create a new
 * array.
 *
 * #GArrowUInt8Array is a class for 8-bit unsigned integer array. It
 * can store zero or more 8-bit unsigned integer data. If you don't
 * have Arrow format data, you need to use #GArrowUInt8ArrayBuilder to
 * create a new array.
 *
 * #GArrowInt16Array is a class for 16-bit integer array. It can store
 * zero or more 16-bit integer data. If you don't have Arrow format
 * data, you need to use #GArrowInt16ArrayBuilder to create a new
 * array.
 *
 * #GArrowUInt16Array is a class for 16-bit unsigned integer array. It
 * can store zero or more 16-bit unsigned integer data. If you don't
 * have Arrow format data, you need to use #GArrowUInt16ArrayBuilder
 * to create a new array.
 *
 * #GArrowInt32Array is a class for 32-bit integer array. It can store
 * zero or more 32-bit integer data. If you don't have Arrow format
 * data, you need to use #GArrowInt32ArrayBuilder to create a new
 * array.

 * to create a new array.
 *

 * zero or more 64-bit integer data. If you don't have Arrow format
 * data, you need to use #GArrowInt64ArrayBuilder to create a new
 * array.

 * to create a new array.
 *
 * #GArrowFloatArray is a class for 32-bit floating point array. It
 * can store zero or more 32-bit floating data. If you don't have
 * Arrow format data, you need to use #GArrowFloatArrayBuilder to
 * create a new array.
 *
 * #GArrowDoubleArray is a class for 64-bit floating point array. It
 * can store zero or more 64-bit floating data. If you don't have
 * Arrow format data, you need to use #GArrowDoubleArrayBuilder to
 * create a new array.
 *
 * #GArrowBinaryArray is a class for binary array. It can store zero
 * or more binary data. If you don't have Arrow format data, you need
 * to use #GArrowBinaryArrayBuilder to create a new array.
 *
 * #GArrowLargeBinaryArray is a class for 64-bit offsets binary array.
 * It can store zero or more binary data. If you don't have Arrow

 * a new array.
 *
 * #GArrayStringViewArray is a class for variable-size string view array.
 * It can store zero or more string view data. If you don't have Arrow
 * format data, you need to use #GArrowStringViewArrayBuilder to create

 * epoch in 32-bit signed integer array. It can store zero or more
 * date data. If you don't have Arrow format data, you need to use
 * #GArrowDate32ArrayBuilder to create a new array.
 *
 * #GArrowDate64Array is a class for the number of milliseconds since
 * UNIX epoch in 64-bit signed integer array. It can store zero or
 * more date data. If you don't have Arrow format data, you need to
