Class StaticExpressionValueComputer

java.lang.Object
com._1c.g5.v8.dt.internal.bsl.resource.StaticExpressionValueComputer
All Implemented Interfaces:
IStaticExpressionValueComputer
public class StaticExpressionValueComputer extends Object implements IStaticExpressionValueComputer
The computer allow to get various types of string static content from code. This computer supports only simple binary operations and variable assignments, so it returns only single and statically computed string content. In case of cycles or some variable computing logic of string concatenation this computer should brake and return null.
