Method Summary

<T> T	evaluateSimpleExpression(String simpleExpression, org.camunda.bpm.engine.variable.context.VariableContext variableContext) Evaluate a FEEL simple expression
boolean	evaluateSimpleUnaryTests(String simpleUnaryTests, String inputName, org.camunda.bpm.engine.variable.context.VariableContext variableContext) Evaluate a FEEL simple unary tests expression

Method Detail

evaluateSimpleExpression

<T> T evaluateSimpleExpression(String simpleExpression,
                               org.camunda.bpm.engine.variable.context.VariableContext variableContext)

Evaluate a FEEL simple expression

Type Parameters:

T - the expected return type

Parameters:

simpleExpression - the simple expression to evaluate

variableContext - the variable context which are available

Returns:

the result of the simple expression

Throws:

FeelException - if the expression cannot be evaluated

evaluateSimpleUnaryTests

boolean evaluateSimpleUnaryTests(String simpleUnaryTests,
                                 String inputName,
                                 org.camunda.bpm.engine.variable.context.VariableContext variableContext)

Evaluate a FEEL simple unary tests expression

Parameters:

simpleUnaryTests - the simple unary tests expression to evaluate

inputName - the name of the variable which is tested

variableContext - the variable context are available

Returns:

the result of the simple unary tests expression

Throws:

FeelException - if the expression cannot be evaluated
