+// Image files are an alternate file format for storing classes and resources. The
+// goal is to supply file access which is faster and smaller than 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 mapped into memory without endian
+// translation. This also means that images are platform dependent.
+//
+// Image files are structured as three sections;
+//
+// +-----------+
+// | Header |
+// +-----------+
+// | |
+// | Index |
+// | |
+// +-----------+
+// | |
+// | |
+// | Resources |
+// | |
+// | |
+// +-----------+
+//
+// The header contains information related to identification and description of
+// contents.
+//
+// +-------------------------+
+// | Magic (0xCAFEDADA) |
+// +------------+------------+
+// | Major Vers | Minor Vers |
+// +------------+------------+
+// | Flags |
+// +-------------------------+
+// | Resource Count |
+// +-------------------------+
+// | Table Length |
+// +-------------------------+
+// | 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.
+// Flags - various image wide flags (future).
+// Resource count - number of resources in the file.
+// Table length - the length of lookup tables used in the index.
+// 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
+// index and meta data.
+//
+// The index 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 ///. return the resource location
+// information;
+//
+// redirectIndex = hash(path, DEFAULT_SEED) % table_length;
+// redirect = redirectTable[redirectIndex];
+// if (redirect == 0) return not found;
+// locationIndex = redirect < 0 ? -1 - redirect : hash(path, redirect) % table_length;
+// 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 index;
+//
+// +-------------------+
+// | 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. Offset of zero
+// indicates no attributes.
+// Attribute Data - Bytes representing compact attribute data for locations. (See
+// comments in ImageLocation.)
+// Strings - Collection of zero terminated UTF-8 strings used by the index 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 index assumes 32 bit alignment of each component
+// in the index.
+//
+// Endianness of an image.
+// An image booted by hotspot is always in native endian. However, it is possible

+// Manage image file location attribute data. Within an image, a location's

+// 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 index.
+// - 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.
