Enum Constant Details

LEGACY

public static final ExpressionParserFactory.ParserStyle LEGACY

The pure legacy parser, using only JEP style syntax and evaluation. Evaluation is done using JEP which has performance limitations and is not thread-safe.

LEGACY_EMULATED

public static final ExpressionParserFactory.ParserStyle LEGACY_EMULATED

The emulated legacy parser, using JEP syntax translated into Java syntax with high speed Java bytecode evaluation.

JAVA

public static final ExpressionParserFactory.ParserStyle JAVA

The Java syntax parser, using ony Java language syntax and high speed bytecode evaluation.

Method Details

values

public static ExpressionParserFactory.ParserStyle[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static ExpressionParserFactory.ParserStyle valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
