Trait containing all DataInputStream methods.

Implementors

DataInputStream

Required methods

Gets the byte order for the data input stream.

Returns

the self’s current DataStreamByteOrder.

Gets the current newline type for the self.

Returns

DataStreamNewlineType for the given self.

Reads an unsigned 8-bit/1-byte value from self.

cancellable

optional Cancellable object, None to ignore.

Returns

an unsigned 8-bit/1-byte value read from the self or 0 if an error occurred.

Reads a 16-bit/2-byte value from self.

In order to get the correct byte order for this read operation, see byte_order() and set_byte_order().

cancellable

optional Cancellable object, None to ignore.

Returns

a signed 16-bit/2-byte value read from self or 0 if an error occurred.

Reads a signed 32-bit/4-byte value from self.

In order to get the correct byte order for this read operation, see byte_order() and set_byte_order().

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore.

Returns

a signed 32-bit/4-byte value read from the self or 0 if an error occurred.

Reads a 64-bit/8-byte value from self.

In order to get the correct byte order for this read operation, see byte_order() and set_byte_order().

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore.

Returns

a signed 64-bit/8-byte value read from self or 0 if an error occurred.

Reads an unsigned 16-bit/2-byte value from self.

In order to get the correct byte order for this read operation, see byte_order() and set_byte_order().

cancellable

optional Cancellable object, None to ignore.

Returns

an unsigned 16-bit/2-byte value read from the self or 0 if an error occurred.

Reads an unsigned 32-bit/4-byte value from self.

In order to get the correct byte order for this read operation, see byte_order() and set_byte_order().

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore.

Returns

an unsigned 32-bit/4-byte value read from the self or 0 if an error occurred.

Reads an unsigned 64-bit/8-byte value from self.

In order to get the correct byte order for this read operation, see byte_order().

If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional Cancellable object, None to ignore.

Returns

an unsigned 64-bit/8-byte read from self or 0 if an error occurred.

This function sets the byte order for the given self. All subsequent reads from the self will be read in the given order.

order

a DataStreamByteOrder to set.

Sets the newline type for the self.

Note that using G_DATA_STREAM_NEWLINE_TYPE_ANY is slightly unsafe. If a read chunk ends in “CR” we must read an additional byte to know if this is “CR” or “CR LF”, and this might block if there is no more data available.

type_

the type of new line return as DataStreamNewlineType.
