LineRangeActivationState activationState ( ) [inherited]

Definition at line 119 of file muSED.cxx.

Here is the caller graph for this function:

bool active	(	ScriptRuntimeContext *	context,
		Statement *	statement
	)			`[inherited]`

return true if the patternBuffer, line number, and isLast_ flag in the specified context match the requirements of the filters.

Parameters:

`[in]`	context	The runtime context in which to determine if the current statement, as defined both by the statement pointer and by line number information in the context, is active.
`[in]`	statement	The statement about to be executed on the current line of input as defined by the line number and is last flag in the context.

Note that the runtime context keeps track of the activation status of statements, by the statement pointer, based on the filters in a filterable statement. Whenever you have a range filter, the activate function manages the activation state.
