Interface JexlEngine.Options

Enclosing class:: JexlEngine

public static interface JexlEngine.Options

Script evaluation options.

The JexlContext used for evaluation can implement this interface to alter behavior.

Method Summary
`MathContext`	`getArithmeticMathContext()` The MathContext instance used for +,-,/,*,% operations on big decimals.
`int`	`getArithmeticMathScale()` The BigDecimal scale used for comparison and coercion operations.
`Charset`	`getCharset()` The charset used for parsing.
`Boolean`	`isCancellable()` Whether evaluation will throw JexlException.Cancel (true) or return null (false) when interrupted.
`Boolean`	`isSilent()` Sets whether the engine will throw a `JexlException` when an error is encountered during evaluation.
`Boolean`	`isStrict()` Checks whether the engine considers unknown variables, methods, functions and constructors as errors or evaluates them as null.
`Boolean`	`isStrictArithmetic()` Checks whether the arithmetic triggers errors during evaluation when null is used as an operand.

Method Detail

getCharset

Charset getCharset()

The charset used for parsing.

Returns:: the charset

isSilent

Boolean isSilent()

Sets whether the engine will throw a JexlException when an error is encountered during evaluation.

Returns:: true if silent, false otherwise

isStrict

Boolean isStrict()

Checks whether the engine considers unknown variables, methods, functions and constructors as errors or evaluates them as null.

Returns:: true if strict, false otherwise

isStrictArithmetic

Boolean isStrictArithmetic()

Checks whether the arithmetic triggers errors during evaluation when null is used as an operand.

Returns:: true if strict, false otherwise

isCancellable

Boolean isCancellable()

Whether evaluation will throw JexlException.Cancel (true) or return null (false) when interrupted.

Returns:: true when cancellable, false otherwise
Since:: 3.1

getArithmeticMathContext

MathContext getArithmeticMathContext()

The MathContext instance used for +,-,/,*,% operations on big decimals.

Returns:: the math context

getArithmeticMathScale

int getArithmeticMathScale()

The BigDecimal scale used for comparison and coercion operations.

Returns:: the scale
