Class DataInput

source code

I provide a set of methods for reading binary data with ActionScript 3.0.

This class is the I/O counterpart to the DataOutput class, which writes binary data.

init(self, decoder=None)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Parameters:

decoder (amf3.Decoder) - AMF3 decoder containing the stream.

Overrides: object.__init__

readBoolean(self)

source code

Read Boolean.

Returns: bool

A Boolean value, True if the byte is nonzero, False otherwise.

Raises:

ValueError - Error reading Boolean.

readByte(self)

source code

Reads a signed byte.

Returns: int: The returned value is in the range -128 to 127.

readDouble(self)

source code

Reads an IEEE 754 double-precision floating point number from the data stream.

Returns: number: An IEEE 754 double-precision floating point number.

readFloat(self)

source code

Reads an IEEE 754 single-precision floating point number from the data stream.

Returns: number: An IEEE 754 single-precision floating point number.

readInt(self)

source code

Reads a signed 32-bit integer from the data stream.

Returns: int: The returned value is in the range -2147483648 to 2147483647.

readMultiByte(self, length, charset)

source code

Reads a multibyte string of specified length from the data stream using the specified character set.

Parameters:

length (int) - The number of bytes from the data stream to read.
charset (str) - The string denoting the character set to use.

Returns: str

UTF-8 encoded string.

readObject(self)

source code

Reads an object from the data stream.

Returns:: The deserialized object.

readShort(self)

source code

Reads a signed 16-bit integer from the data stream.

Returns: uint: The returned value is in the range -32768 to 32767.

readUnsignedByte(self)

source code

Reads an unsigned byte from the data stream.

Returns: uint: The returned value is in the range 0 to 255.

readUnsignedInt(self)

source code

Reads an unsigned 32-bit integer from the data stream.

Returns: uint: The returned value is in the range 0 to 4294967295.

readUnsignedShort(self)

source code

Reads an unsigned 16-bit integer from the data stream.

Returns: uint: The returned value is in the range 0 to 65535.

readUTF(self)

source code

Reads a UTF-8 string from the data stream.

The string is assumed to be prefixed with an unsigned short indicating the length in bytes.

Returns: str: A UTF-8 string produced by the byte representation of characters.

readUTFBytes(self, length)

source code

Reads a sequence of length UTF-8 bytes from the data stream and returns a string.

Parameters:

length (int) - The number of bytes from the data stream to read.

Returns: str

A UTF-8 string produced by the byte representation of characters of specified length.
