read(type, offset = binary.tell()): Read value of specified type. If offset given, read it from custom position, otherwise read it from current position and move pointer forward (streaming mode).var firstInt = binary.read('uint32'); // uint32 value at offset 0
var secondInt = binary.read('uint32'); // following uint32 value at offset 4
var byteAtOffset100 = binary.read('uint8', 100); // uint8 value at custom position
var thirdInt = binary.read('uint32'); // third uint32 value at offset 8 (since read operation with custom position didn't move internal pointer)
readAll(): Read entire data as value of type specified by 'jBinary.all' key in typeset.
write(type, data, offset = binary.tell()): Write value of specified type. Same offset behavior.
binary.write('uint32', 1); // writing uint32 value of 1 at offset 0
binary.write('uint32', 2); // writing uint32 value of 2 at offset 4
binary.write('uint8', 0xff, 100); // writing uint8 value of 255 at offset 100
binary.write('uint32', 3); // writing uint32 value of 3 at offset 8
writeAll(data): Write entire data as value of type specified by 'jBinary.all' key in typeset.tell(): Return the current position.var currentPos = binary.tell();
seek(position[, callback]): Go to position; if callback is given, execute it and return to the previous position.binary.seek(100); // just went to offset 100
var intAt200 = binary.seek(200, function () { return this.binary.read('int32') }); // go to offset 200, get int32 value there and return back to offset 100
skip(count[, callback]): Advance in the binary by count bytes; same callback behavior.binary.skip(1); // just skip one byte we are not interested in
var intAfter8 = binary.skip(8, function () { return this.binary.read('int32') }); // go 8 bytes forward, get int32 value there and return back
slice(start, end, forceCopy = false): Returns sliced version of current binary with same type set. If forceCopy set to true, underlying jDataView will be created on copy of original data not linked to it.var pointerSlice = binary.slice(10, 20); // now you can manipulate on this jBinary instance and all the changes will be mirrored to original binary's data, but with new bound check rules var copySlice = binary.slice(10, 20, true); // now you can manipulate on this jBinary instance as on absolutely new one and any data changes will stay isolated from original binary
as(typeSet, modifyOriginal = false): Casts jBinary instance to given typeSet while pointing to the same data, pointers and methods as original instance; if modifyOriginal set to true, original instance will be modified instead of being inherited.var binary = someExternalBinary.as(TAR); // casting external jBinary instance with no or with irrelevant typeset to TAR typeSet object (any operations including both data and pointer manipulations will affect both instances).
