Buffer class

This provides methods to read and write strings, lists and various sized integers on a buffer (implemented as an integer list).

The ints in the backing list must all be 8-bit values. If larger values are entered, behaviour is undefined.

As per mysql spec, numbers here are all unsigned. Which makes things much easier.

Constructors

Buffer(int size): Creates a Buffer of the given size
Buffer.fromList(List<int> list): Creates a Buffer with the given list as backing storage

Properties

hashCode → int: The hash code for this object.
no setterinherited
hasMore → bool: no setter
length → int: Returns the size of the buffer
no setter
list → Uint8List: no setter
log → Logger: final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

Methods

canReadMore() → bool: Returns true if more data can be read from the buffer, false otherwise.
fill(int numberOfBytes, int value) → void: Fills the next numberOfBytes with the given value
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
readByte() → int: Returns a single byte, read from the buffer.
readDouble() → double
readFloat() → double
readFromSocket(RawSocket socket, int count) → int: Reads up to count bytes from the socket into the buffer. Returns the number of bytes read.
readInt16() → int: Returns a 16-bit integer, read from the buffer
readInt32() → int: Returns a 32-bit integer, read from the buffer.
readInt64() → int: Returns a 64-bit integer, read from the buffer.
readLengthCodedBinary() → int?: Reads a length coded binary from the buffer. This is specified in the mysql docs. It will read up to nine bytes from the stream, depending on the first byte. Returns an unsigned integer.
readLengthCodedString() → String?: Returns a length coded string, read from the buffer.
readList(int numberOfBytes) → List<int>: Returns a list of the given numberOfBytes, read from the buffer.
readNullTerminatedList() → List<int>: Reads a null terminated list of ints from the buffer. Returns the list of ints from the buffer, without the terminating zero
readNullTerminatedString() → String: Reads a null terminated string from the buffer. Returns the string, without a terminating null.
readString(int length) → String: Reads a string of the given length from the buffer.
readStringToEnd() → String: Reads a string from the buffer, terminating when the end of the buffer is reached.
readUint16() → int: Returns a 16-bit integer, read from the buffer
readUint24() → int: Returns a 24-bit integer, read from the buffer.
readUint32() → int: Returns a 32-bit integer, read from the buffer.
readUint64() → int: Returns a 64-bit integer, read from the buffer.
reset() → void: Resets the read and write positions markers to the start of the buffer */
seek(int position) → void: Moves the read marker to the given position
seekWrite(int position) → void: Moves the write marker to the given position
skip(int numberOfBytes) → void: Moves the read marker forwards by the given numberOfBytes
skipWrite(int numberOfBytes) → void: Moves the write marker forwards by the given numberOfBytes
toString() → String: A string representation of this object.
inherited
writeByte(int byte) → void: Writes a single byte to the buffer.
writeDouble(double value) → void
writeFloat(double value) → void
writeInt16(int integer) → void: Writes a 16 bit integer to the buffer.
writeInt32(int integer) → void: Writes a 32 bit integer to the buffer.
writeInt64(int integer) → void: Writes a 64 bit integer to the buffer.
writeLengthCodedBinary(int value) → void: Will write a length coded binary value, once implemented!
writeList(List<int> list) → void: Writes the give list of bytes to the buffer.
writeNullTerminatedList(List<int> list) → void: Writes a null terminated list of ints from the buffer. The given list should not contain the terminating zero.
writeToSocket(RawSocket socket, int start, int count) → int: Writes up to count bytes to the socket from the buffer. Returns the number of bytes written.
writeUint16(int integer) → void: Writes a 16 bit integer to the buffer.
writeUint24(int integer) → void: Writes a 24 bit integer to the buffer.
writeUint32(int integer) → void: Writes a 32 bit integer to the buffer.
writeUint64(int integer) → void: Writes a 64 bit integer to the buffer.

Operators

operator ==(Object other) → bool: The equality operator.
inherited
operator [](int index) → int: Returns the int at the specified index
operator []=(int index, int value) → void: Sets the int at the specified index to the given value

Static Methods

debugChars(Uint8List list) → String
listChars(Uint8List list) → String
measureLengthCodedBinary(int value) → int
