Reads chunks of a file from the disc. Supports reading multiple chunks concurrently (underlying RandomAccessFile forbids this).

Methods
-
dispose(
) → void -
closes the underlying file
override
-
freeRessources(
) → void -
frees the underlying files. This is meant to be used when sending to an isolate
override
-
getPosition(
) → int -
Returns the current position in the readbuffer source
override
-
length(
) → Future< int> -
returns the length of the file. If needed this method may be removed but the length check must be done in the individual read-methods then.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
readFromFile(
int length) → Future< Readbuffer> -
Reads the given amount of bytes from the file into the read buffer and resets the internal buffer position. If
the capacity of the read buffer is too small, a larger one is created automatically.
override
-
readFromFileAt(
int position, int length) → Future< Readbuffer> -
override
-
setPosition(
int position) → Future< void> -
override
-
toString(
) → String -
A string representation of this object.
override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
