InputBuffer class - image library

Constructors

InputBuffer(List<int> buffer, {bool bigEndian = false, int offset = 0, int? length}): Create a InputStream for reading from a List
InputBuffer.from(InputBuffer other, {int offset = 0, int? length}): Create a copy of other.

Properties

bigEndian ↔ bool: getter/setter pair
buffer ↔ List<int>: getter/setter pair
end → int: final
hashCode → int: The hash code for this object.
no setterinherited
isEOS → bool: Is the current position at the end of the stream?
no setter
length → int: How many bytes are left in the stream.
no setter
offset ↔ int: getter/setter pair
position → int: The current read position relative to the start of the buffer.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
start → int: final

Methods

indexOf(int value, [int offset = 0]) → int: Returns the position of the given value within the buffer, starting from the current read position with the given offset. The position returned is relative to the start of the buffer, or -1 if the value was not found.
memcpy(int start, int length, dynamic other, [int offset = 0]) → void: Copy data from other to this buffer, at start offset from the current read position, and length number of bytes. offset is the offset in other to start reading.
memset(int start, int length, int value) → void: Set a range of bytes in this buffer to value, at start offset from the current read position, and length number of bytes.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
peekBytes(int count, [int offset = 0]) → InputBuffer: Read count bytes from an offset of the current read position, without moving the read position.
readByte() → int: Read a single byte.
readBytes(int count) → InputBuffer: Read count bytes from the stream.
readFloat32() → double: Read a 32-bit float.
readFloat64() → double: Read a 64-bit float.
readInt16() → int: Read a 16-bit word from the stream.
readInt32() → int: Read a signed 32-bit integer from the stream.
readInt8() → int
readString([int? len]) → String: Read a null-terminated string, or if len is provided, that number of bytes returned as a string.
readStringUtf8() → String: Read a null-terminated UTF-8 string.
readUint16() → int: Read a 16-bit word from the stream.
readUint24() → int: Read a 24-bit word from the stream.
readUint32() → int: Read a 32-bit word from the stream.
readUint64() → int: Read a 64-bit word form the stream.
rewind() → void: Reset to the beginning of the stream.
skip(int count) → void: Move the read position by count bytes.
subset(int count, {int? position, int offset = 0}) → InputBuffer: Return a InputStream to read a subset of this stream. It does not move the read position of this stream. position is specified relative to the start of the buffer. If position is not specified, the current read position is used. If length is not specified, the remainder of this stream is used.
toList([int offset = 0, int length = 0]) → List<int>
toString() → String: A string representation of this object.
inherited
toUint32List([int offset = 0]) → Uint32List
toUint8List([int offset = 0, int? length]) → Uint8List

Operators

operator ==(Object other) → bool: The equality operator.
inherited
operator [](int index) → int: Access the buffer relative from the current position.
operator []=(int index, int value) → void: Set a buffer element relative to the current position.
