readFromSync method

num readFromSync(
  1. ReaderSync r
)

Reads data from r until EOF (null) and appends it to the buffer, growing the buffer as needed. It returns the number of bytes read. If the buffer becomes too large, .readFromSync() will throw an error.

Based on Go Lang's Buffer.ReadFrom.

Implementation

_i2.num readFromSync(_i4.ReaderSync r) => _i3.callMethod(
      this,
      'readFromSync',
      [r],
    );
