Methods

dispose() → void
Releases all interal native resoures.
getErrno() int
Returns the libc errno of the last failure that occurred.
getMMIOinfo() String
Returns a string representation of the MMIO handle.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
read(int offset, int len) List<int>
Reads an byte array from mapped physical memory, starting at the specified byte offset, relative to the base address the MMIO handle was opened with.
read8(int offset) int
Reads 8-bits from mapped physical memory, starting at the specified byte offset, relative to the base address the MMIO handle was opened with.
read16(int offset) int
Reads 16-bits from mapped physical memory, starting at the specified byte offset, relative to the base address the MMIO handle was opened with.
read32(int offset) int
Reads 32-bits from mapped physical memory, starting at the specified byte offset, relative to the base address the MMIO handle was opened with.
toString() String
A string representation of this object. [...]
inherited
write(int offset, List<int> data) → void
Writes an byte array from mapped physical memory, starting at the specified byte offset, relative to the base address the MMIO handle was opened with.
write8(int offset, int value) → void
Writes 8-bits from mapped physical memory, starting at the specified byte offset, relative to the base address the MMIO handle was opened with.
write16(int offset, int value) → void
