Constructor Detail

WfInstruction

public WfInstruction(String an_instruction)

Creates a new WfInstruction with the String passed in as an argument. The passed in String is trimmed to 4000 characters (single byte), so it will fit in the Instructions attribute of the WfProcess or WfActivity objects.

Supported API: false

Parameters:

an_instruction -

WfInstruction

public WfInstruction(StringBuffer an_instruction)

Creates a new WfInstruction with using the StringBuffer passed in as the argument.. The passed in String is trimmed to 4000 characters (single byte), so it will fit in the Instructions attribute of the WfProcess or WfActivity objects.

Supported API: false

Parameters:

an_instruction -

WfInstruction

public WfInstruction()

Creates a new WfInstruction - no arg constructor.
