Unflatten from Byte Array (G Dataflow)

Version:
    Last Modified: March 15, 2017

    Converts a flattened byte array to a data type you specify.

    type

    The data type to which you want to convert the data.

    Wire any constant or control to this input to set the data type to which you want to convert the data. This node ignores any data in the constant or control you wire to this input.

    datatype_icon

    data bytes

    A flattened byte array of the input data that this node can unflatten.

    If data includes array or string size? is True, data bytes contains header information describing its size.

    data bytes must contain flattened data of the original data type that you wired to type.

    datatype_icon

    data includes array or string size?

    A Boolean that indicates whether the node reads data size information from the beginning of an incoming array or string.

    data includes array or string size only accesses the top-level data size information. Arrays and strings in hierarchical data types such as clusters always include size information.

    True Reads the size information from the beginning of data bytes.
    False Detects the size information from the memory size of data bytes.

    Default: True

    datatype_icon

    byte order

    The endian format of the data in the resulting output. Byte order, or endian form, indicates whether integers are represented in memory from most-significant byte to least-significant byte or vice versa. When reading a binary file, you must interpret the data in the same byte order in which the data was written.

    Name Description
    big-endian, network order

    The most-significant byte occupies the lowest memory address. Use this endian format when reading data written on a different platform.

    native, host-order

    Uses the byte-ordering format of the host computer. This endian format increases read and write speed.

    little-endian

    The least-significant byte occupies the lowest memory address.

    Default: big-endian, network order

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    remainder of the data bytes

    Bytes that this node did not convert.

    This node does not convert all the bytes if the size of data bytes is not a multiple of the size of type.

    datatype_icon

    value

    Data unflattened by this node from data bytes to the same data type and structure as type.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
