RealBufferedSource(Source source)

Properties

buffer → Buffer

This source's internal buffer.

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

close() → Future<void>

Closes this source and releases the resources held by this source. It is an error to read a closed source. It is safe to close a source more than once.

override

exhausted() → Future<bool>

Returns true if there are no more bytes in this source.

override

indexOf(int element, [int start = 0, int? end]) → Future<int>

Returns the index of element if it is found in the range of start inclusive to end exclusive. If element isn't found, or if start == end, then -1 is returned.

override

indexOfBytes(Uint8List bytes, [int start = 0, int? end]) → Future<int>

Returns the index of the first match for bytes in the range of start inclusive to end exclusive. This expands the buffer as necessary until bytes is found. This reads an unbounded number of bytes into the buffer. Returns -1 if the stream is exhausted before the requested bytes are found.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

peek() → FutureOr<BufferedSource>

Returns a new BufferedSource that can read data from this BufferedSource without consuming it. The returned source becomes invalid once this source is next read or closed.

override

rangeEquals(int offset, List<int> bytes, [int start = 0, int? end]) → Future<bool>

Returns true if end - start bytes at offset in this source equal bytes at start. This expands the buffer as necessary until a byte does not match, all bytes are matched, or if the stream is exhausted before enough bytes could determine a match.

override

read(Buffer sink, int count) → Future<int>

Removes at least 1, and up to count bytes from this and appends them to sink. Returns the number of bytes read, or 0 if this source is exhausted.

override

readBytes([int? count]) → Future<Uint8List>

Removes bytes (all bytes if count is null) from this and returns them as a list of bytes.

override

readFloat32([Endian endian = Endian.big]) → Future<double>

Removes four bytes from this source.

override

readFloat64([Endian endian = Endian.big]) → Future<double>

Removes eight bytes from this source.

override

readInt16([Endian endian = Endian.big]) → Future<int>

Removes two bytes from this source.

override

readInt32([Endian endian = Endian.big]) → Future<int>

Removes four bytes from this source.

override

readInt64([Endian endian = Endian.big]) → Future<int>

Removes eight bytes from this source.

override

readInt8() → Future<int>

Removes a byte from this source.

override

readIntoBytes(List<int> sink, [int start = 0, int? end]) → Future<int>

Removes exactly end - start bytes from this and copies them into sink.

override

readIntoSink(Sink sink) → Future<int>

Removes all bytes from this and appends them to sink. Returns the total number of bytes written to sink which will be 0 if this is exhausted.

override

readLine({Encoding encoding = utf8}) → Future<String?>

Removes and returns characters up to but not including the next line break. A line break is either "\n" or "\r\n"; these characters are not included in the result.

override

readLineStrict({Encoding encoding = utf8, int? end}) → Future<String>

Removes and returns characters up to but not including the next line break. A line break is either "\n" or "\r\n"; these characters are not included in the result.

override

readString({Encoding encoding = utf8, int? count}) → Future<String>

Removes bytes (all bytes if count is null) from this and returns the string. Returns the empty string if this source is empty.

override

readUint16([Endian endian = Endian.big]) → Future<int>

Removes two bytes from this source.

override

readUint32([Endian endian = Endian.big]) → Future<int>

Removes four bytes from this source.

override

readUint64([Endian endian = Endian.big]) → Future<int>

Removes eight bytes from this source.

override

readUint8() → Future<int>

Removes a byte from this source.

override

request(int count) → Future<bool>

Returns true when the buffer contains at least count bytes, expanding it as necessary. Returns false if the source is exhausted before the requested bytes can be read.

override

require(int count) → Future<void>

Returns when the buffer contains at least count bytes. Throws an EOFException if the source is exhausted before the required bytes can be read.

override

skip(int count) → Future<void>

Reads and discards count bytes from this source. Throws an EOFException if the source is exhausted before the requested bytes can be skipped.

override

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.
