Use the Parse-Byte-Pos method in the Steps tab of a Parse Structured rule (Rule-Parse-Structured rule type) to extract a fixed number of bytes from the input Java byte stream into a clipboard property value.
You cannot use this method in an activity. You cannot use this method if the associated input is a character stream rather than a byte stream.
This method has three parameters:
Parameter |
Description |
| Offset | Enter a non-negative number of bytes to move the selection point from current byte position before copying data. |
| Length | Enter a number of bytes to select. |
| TargetProperty | Optional. Identify a Single Value target property to hold the resulting value. |
The system reads the specified number of bytes from the input byte stream. It converts these bytes into a string using the character encoding specified in the associated ParseState object. (This is ordinarily the default character encoding for the UNIX or Windows platform hosting PRPC.)
If the TargetProperty field is not blank, it sets the result as the value of the property identified. If the target property is not present on the clipboard, it is added.
This method updates the pxMethodStatus property. See How to test method results using a transition.
