#include "memory/allocation.inline.hpp"
#include "utilities/globalDefinitions.hpp"
// Image files are an alternate file format for storing classes and resources. The
// goal is to supply file access which is faster and smaller that the jar format.
// It should be noted that unlike jars information stored in an image is in native
// endian format. This allows the image to be memory mapped into memory without
// endian translation. This also means that images are platform dependent.
//
// Image files are structured as three sections;
//
// +-----------+
// | Header |
// +-----------+
// | |
// | Directory |
// | |
// +-----------+
// | |
// | |
// | Resources |
// | |
// | |
// +-----------+
//
// The header contains information related to identification and description of
// contents.
//
// +-------------------------+
// | Magic (0xCAFEDADA) |
// +------------+------------+
// | Major Vers | Minor Vers |
// +------------+------------+
// | Location Count |
// +-------------------------+
// | Attributes Size |
// +-------------------------+
// | Strings Size |
// +-------------------------+
//
// Magic - means of identifying validity of the file. This avoids requiring a
// special file extension.
// Major vers, minor vers - differences in version numbers indicate structural
// changes in the image.
// Location count - number of locations/resources in the file. This count is also
// the length of lookup tables used in the directory.
// Attributes size - number of bytes in the region used to store location attribute
// streams.
// Strings size - the size of the region used to store strings used by the
// directory and meta data.
//
// The directory contains information related to resource lookup. The algorithm
// used for lookup is "A Practical Minimal Perfect Hashing Method"
// (http://homepages.dcc.ufmg.br/~nivio/papers/wea05.pdf). Given a path string
// in the form <package>/<base>.<extension> return the resource location
// information;
//
// redirectIndex = hash(path, DEFAULT_SEED) % count;
// redirect = redirectTable[redirectIndex];
// if (redirect == 0) return not found;
// locationIndex = redirect < 0 ? -1 - redirect : hash(path, redirect) % count;
// location = locationTable[locationIndex];
// if (!verify(location, path)) return not found;
// return location;
//
// Note: The hash function takes an initial seed value. A different seed value
// usually returns a different result for strings that would otherwise collide with
// other seeds. The verify function guarantees the found resource location is
// indeed the resource we are looking for.
//
// The following is the format of the directory;
//
// +-------------------+
// | Redirect Table |
// +-------------------+
// | Attribute Offsets |
// +-------------------+
// | Attribute Data |
// +-------------------+
// | Strings |
// +-------------------+
//
// Redirect Table - Array of 32-bit signed values representing actions that
// should take place for hashed strings that map to that
// value. Negative values indicate no hash collision and can be
// quickly converted to indices into attribute offsets. Positive
// values represent a new seed for hashing an index into attribute
// offsets. Zero indicates not found.
// Attribute Offsets - Array of 32-bit unsigned values representing offsets into
// attribute data. Attribute offsets can be iterated to do a
// full survey of resources in the image.
// Attribute Data - Bytes representing compact attribute data for locations. (See
// comments in ImageLocation.)
// Strings - Collection of zero terminated UTF-8 strings used by the directory and
// image meta data. Each string is accessed by offset. Each string is
// unique. Offset zero is reserved for the empty string.
//
// Note that the memory mapped directory assumes 32 bit alignment of the image
// header, the redirect table and the attribute offsets.
//
// Manage image file string table.

// copying.

};
// Manage image file location attribute streams. Within an image, a location's
// attributes are compressed into a stream of bytes. An attribute stream is
// composed of individual attribute sequences. Each attribute sequence begins with
// a header byte containing the attribute 'kind' (upper 5 bits of header) and the
// 'length' less 1 (lower 3 bits of header) of bytes that follow containing the
// attribute value. Attribute values present as most significant byte first.
//
// Ex. Container offset (ATTRIBUTE_OFFSET) 0x33562 would be represented as 0x22
// (kind = 4, length = 3), 0x03, 0x35, 0x62.
//
// An attribute stream is terminated with a header kind of ATTRIBUTE_END (header
// byte of zero.)
//
// ImageLocation inflates the stream into individual values stored in the long
// array _attributes. This allows an attribute value can be quickly accessed by
// direct indexing. Unspecified values default to zero.
//
// Notes:
// - Even though ATTRIBUTE_END is used to mark the end of the attribute stream,
// streams will contain zero byte values to represent lesser significant bits.
// Thus, detecting a zero byte is not sufficient to detect the end of an attribute
// stream.
// - ATTRIBUTE_OFFSET represents the number of bytes from the beginning of the region
// storing the resources. Thus, in an image this represents the number of bytes
// after the directory.
// - Currently, compressed resources are represented by having a non-zero
// ATTRIBUTE_COMPRESSED value. This represents the number of bytes stored in the
// image, and the value of ATTRIBUTE_UNCOMPRESSED represents number of bytes of the
// inflated resource in memory. If the ATTRIBUTE_COMPRESSED is zero then the value
// of ATTRIBUTE_UNCOMPRESSED represents both the number of bytes in the image and
// in memory. In the future, additional compression techniques will be used and
// represented differently.
// - Package strings include trailing slash and extensions include prefix period.
