Method Detail

evaluateExpressions

HashMap<String,Serializable> evaluateExpressions(HashMap<String,String> expressions,
                                                 Serializable inputData)
                                          throws EXPException

Evaluates a set of expressions in a batch. The API accepts a collection of expressions and input data required to evaluate these expressions and returns a collection of expression results. The input expressions are provided as a map where each expression is mapped against a unique key. The result of API returns a map containing result of the expression mapped to the key of corresponding expression.

Parameters:

expressions - Map of expression keys and expressions.

inputData - input data based on which expressions will be evaluated.

Returns:

map of expression keys and the computed values.

Throws:

EXPException

validateExpression

void validateExpression(String expression)
                 throws EXPException

Validates an expression. Throws exception if syntax of expression is incorrect.

Parameters:

expression - expression required to be validated.

Throws:

EXPException

evaluateExpression

Serializable evaluateExpression(String expression,
                                Serializable inputData)
                         throws EXPException

Evaluates a single expression. The API expects an expression and the input data required to evaluate this expression and returns the computed value of expression.

Parameters:

expression - expression required to be evaluated.

inputData - input data based on which expression will be evaluated.

Returns:

evaluated value of the expression.

Throws:

EXPException

evaluateExpression

Serializable evaluateExpression(String expression,
                                Serializable inputData,
                                String outputVariable)
                         throws EXPException

Evaluates a single expression. The API expects an expression and the input data required to evaluate this expression and returns the computed value of expression.

Parameters:

expression - expression required to be evaluated.

inputData - input data based on which expression will be evaluated.

outputVariable - determine whether splitting is required or not based on outputVariable type

Returns:

evaluated value of the expression.

Throws:

EXPException

getExpressionVariables

List<String> getExpressionVariables(String expression)
                             throws EXPException

Parses the expression and returns the input variables used inside this expression.

Parameters:

expression - expression required to be parsed.

Returns:

variables used inside the expression.

Throws:

EXPException
