LlExprParse Method

In This Topic

Tests the expression for correctness and constructs a function tree for this expression.

You should avoid using this function directly - the ExpressionEvaluator Class offers you a much more powerful way to work with expressions.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Function LlExprParse( _
   ByVal expression As String, _
   ByVal includeFields As Boolean _
) As IntPtr

public IntPtr LlExprParse( 
   string expression,
   bool includeFields
)

public:
IntPtr LlExprParse( 
   String^ expression,
   bool includeFields
)

Parameters

expression

expression

includeFields

Value	Meaning
true	reference to fields
false	reference to variables

Remarks

If an error is signaled (Address = null) then you can query the error text with LlExprError().

The variables defined with LlDefineVariable() can be integrated into the expression if bTablefields is false, otherwise the fields defined with LlDefineField() are included in the expression. If the expression is used for calculation several times it is recommended to translate it once with LlExprParse() and then carry out the calculations, releasing the tree at the end.
