Invocation expressions (PEL)

The following topics describe PerformancePoint Expression Language (PEL) expressions that invoke other PEL elements.

Non-Dotted Function Calls

A non-dotted function call is composed of an identifier that is followed by an expression list in parentheses. The parentheses can be omitted if the expression list is empty.

non-dotted-function-call:
  identifier ( expression-list )
  identifier

Expression Lists

An expression list is a sequence of expressions that is separated by commas. The list can have zero expressions.

expression-list:
  /* empty */
  expression
  expression-list , expression

Dotted Function Calls

A dotted function call is composed of an expression followed by a dot, an identifier, and an expression-list in parentheses. The parentheses can be omitted if the expression-list is empty.

dotted-function-call:
  expression . identifier ( expression-list )
  expression . identifier
  name-list . identifier ( expression-list )
  name-list . identifier

The dotted function call syntax is shorthand for a non-dotted function call: the dotted expression is made the first expression in the expression list. For example, e1.identifier(e2, e3, …, eN) is equivalent to identifier(e1, e2, e3, …, eN).
