Ens.BPL.Assign

class Ens.BPL.Assign extends Ens.BPL.Activity

The syntax specifies a target property and an expression that will be assigned to it:- Assignments ALWAYS have accessible to them certain intrinsic objects which are part of the execution environment. These are the context, process, request,response, status, synctimedout, synchronizedresponses etc. as well as other objects which refer to the corresponding properties in the business process object. When an assignment is performed in the context of a call (defined by the tag in BPL), the callrequest and callresponse object refer to the CURRENT request or response. Note: when in a tag, the callresponse object is undefined, when in a tag, the callrequest object is undefined Assignments can also specify the 'action' attribute which determines how the assignment is performed. Legal values for the 'action' attribute are:- Append,Clear, Insert,Remove and Set. If this attribute is not specified, the default value is 'Set'. Append,Clear, Insert and Remove are only applicable when the property being accessed is a collection of type 'list' or 'array'. Depending upon the type of assignment, an additional attribute 'key' may be required. Here is a table which determines which attributes are required to effect a particular type of assignment. Property Type Assignment Action Key Required Result ------------- --------------- ------------ ------ Non-collection Set No Property is set to new value Array Clear No Array is cleared Array Remove Yes Element at Key is removed Array Set Yes Element at Key is set to new value List Append No Element is added to the end of the list List Clear No List is cleared List Insert Yes Element is inserted at position determined by Key List Remove Yes Element at Key is removed List Set Yes Element at Key is replaced
