This module provides the following classes:
id -> string
Returns true if the id string represents a valid UUID.
Returns an invalid UUID in string form.
Using an internal UUID object this function creates a randomly generated UUID string. Returns the UUID string.
Note: This function should not be called from runtime code because it will generate a different result each time. If using this UUID for a class declaration it's important that the string remain the same over the life of the class.
t -> table
Returns a table meant to replace the supplied table which disallows further modifications, resulting in read-only access.
key -> string
global -> boolean
Removes the value with the given key from persistent storage.
"global" should match what was used in storing the value.
key -> string
global -> boolean
Gets the value string from persistent storage using the given key.
"global" should match what was used in storing the value.
key -> string
value -> string
global -> boolean
Puts the given value string into persistent storage under the given key.
If "global" is true then the value is stored for all users on this machine,
otherwise the value is stored locally for this user only.
This class provides a dynamically allocated block of memory.
This class has the following construction methods:
Memory (numBytes)
numBytes -> integer
Constructs a new block of memory holding uninitialized data of the given size.
Returns the new object.
Memory (block)
block -> Memory
Constructs a new block of memory sharing the same storage with the given block.
Returns the new object.
Every instance of this class has the following member methods:
Please note that the in-memory layout of anything larger than a byte is processor dependent.
Memory:Clone ()
Returns a newly allocated copy of this block of memory.
Memory:GetSize ()
Returns the size in bytes of this block of memory.
Memory:IsValid ()
Returns true if this object holds a valid block of memory.
Memory:Peek (offset)
offset -> integer
Returns the byte at the given offset within this block of memory.
Memory:Peek16 (offset)
Returns the word at the given offset within this block of memory.
offset -> integer
Memory:Peek32 (offset)
offset -> integer
Returns the long word at the given offset within this block of memory.
Memory:Peek64 (offset)
offset -> integer
Returns the long long word at the given offset within this block of memory.
Memory:PeekFloat32 (offset)
offset -> integer
Returns the float at the given offset within this block of memory.
Memory:PeekFloat64 (offset)
Returns the double at the given offset within this block of memory.
offset -> integer
Memory:Poke (offset, value)
offset -> integer
value -> integer
Stores the given byte value at the given offset within this block of memory.
Memory:Poke16 (offset, value)
offset -> integer
value -> integer
Stores the given word value at the given offset within this block of memory.
Memory:Poke32 (offset, value)
offset -> integer
value -> integer
Stores the given long word value at the given offset within this block of memory.
Memory:Poke64 (offset, value)
offset -> integer
value -> integer
Stores the given long long word value at the given offset within this block of memory.
Memory:PokeFloat32 (offset, value)
offset -> integer
value -> double
Stores the given float value at the given offset within this block of memory.
Memory:PokeFloat64 (offset, value)
offset -> integer
value -> double
Stores the given double value at the given offset within this block of memory.
This class provides for generating and comparing Universal Unique Identifiers.
This class has the following construction methods:
UUID ()
Constructs a new UUID object for the invalid ID.
Returns the new object.
UUID (uuid)
uuid -> UUID
Constructs a new UUID object by copying the existing object.
Returns the new object.
UUID (id)
id -> string
Constructs a new UUID object using a UUID string with the format:
"tttttttt-tttt-cccc-cccc-nnnnnnnnnnnn"
Returns the new object.
Every instance of this class has the following member methods:
UUID:Compare (uuid)
uuid -> UUID
Compare two UUIDs "lexically" and return:
-1) this UUID is lexically before the given UUID
0) this UUID is equal to the given UUID
+1) this UUID is lexically after the given UUID
UUID:Get ()
Returns the UUID in string form.
UUID:Hash ()
Returns a 16-bit unsigned integer hash code for this object.
Memory:Invalidate ()
Reverts this UUID to its invalid form.
Memory:IsValid ()
Returns true if this object is a valid UUID.
UUID:Set (id)
id -> string
Sets the UUID in string form.
