## Enumeration Type Documentation

enum gta::result

GTA result.

This is equivalent to gta_result_t from the C interface.

Enumerator
ok | Success / no error.
overflow | Size overflow.
unsupported_data | Unsupported data. The input seems to require features that are not available in this version of the library.
unexpected_eof | Unexpected end of file. The GTA library intended to read more data, but the input did not provide it.
invalid_data | Invalid data. Some data was invalid. For example, an input file is not in GTA format, or decompression of the data failed.
system_error | System error. A system error occured. More information is available in errno. Examples: memory allocation failure (errno == ENOMEM), input/output errors (errno == EIO), no space left on device (errno == ENOSPC).

enum gta::type

GTA data types.

This is equivalent to gta_type_t from the C interface.

All integer types contain the exact number of bits indicated by their name and use the common two's complement representation.
All floating point types contain the exact number of bits indicated by their name and conform to the binary representation defined by IEEE 754.
The complex types (gta::cfloat*) consist of two floating point values with the number of bits indicated by the name, as defined above. The first value is the real part, the second value is the imaginary part. For example, gta::cfloat32 consists of two gta::float32 values.
The name gta::blob can be used for data types that are not defined in this list. In this case, the size of the data type must be given, and the data type must be independent of endianness.

Enumerator
int8 | int8_t
uint8 | uint8_t
int16 | int16_t
uint16 | uint16_t
int32 | int32_t
uint32 | uint32_t
int64 | int64_t
uint64 | uint64_t
int128 | int128_t (unavailable on many platforms)
uint128 | uint128_t (unavailable on many platforms)
float32 | IEEE 754 single precision floating point (on many platforms: float)
float64 | IEEE 754 double precision floating point (on many platforms: double)
float128 | IEEE 754 quadrupel precision floating point (unavailable on many platforms, even if long double exists)
cfloat32 | complex (re,im) based on two gta::float32
cfloat64 | complex (re,im) based on two gta::float64
cfloat128 | complex (re,im) based on two gta::float128
blob | Data blob; must be endianness-independent; user must specify the size.

enum gta::compression

GTA compression methods.

This is equivalent to gta_compression_t from the C interface.

Compression algorithms used to compress the array.
Only uncompressed files are suitable for out-of-core data access; compressed files must be decompressed first.
gta::zlib compression is fast and achieves a moderate compression ratio. gta::bzip2 compression is moderately fast and achieves a good compression ratio. gta::xz compression is slow for compression, moderately fast for decompression, and achieves good or very good compression rates.

Enumerator
none | No compression.
zlib | ZLIB compression (fast, moderate compression rate)
zlib1 | ZLIB compression with level 1.
zlib2 | ZLIB compression with level 2.
zlib3 | ZLIB compression with level 3.
zlib4 | ZLIB compression with level 4.
zlib5 | ZLIB compression with level 5.
zlib6 | ZLIB compression with level 6.
zlib7 | ZLIB compression with level 7.
zlib8 | ZLIB compression with level 8.
zlib9 | ZLIB compression with level 9.
bzip2 | BZIP2 compression (moderate speed, good compression rates)
xz | XZ compression (low/moderate speed, good/very good compression rates)
