@Beta
public static enum YangXPathParserFactory.MathMode
extends Enum<YangXPathParserFactory.MathMode>

YangXPathParser number compliance knobs. This enumeration defines what assumptions the parser can make -- affecting its optimization properties around constant folding when number expressions are involved.

Enum Constant Detail

IEEE754

public static final YangXPathParserFactory.MathMode IEEE754

All number expressions are treated as double. This in spirit of XPath 1.0 -- any number expression starts its life as a double, making all operations subject to IEEE754 rounding and range rules.

EXACT

public static final YangXPathParserFactory.MathMode EXACT

All number expressions are treated as infinite-precision numbers. This follows the spirit of YANG 1.1 -- where mostly have integral types and decimal64 mapped to BigDecimal. Non-decimal numbers are mapped either to int, long or BigInteger.

Method Detail

values

public static YangXPathParserFactory.MathMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (YangXPathParserFactory.MathMode c : YangXPathParserFactory.MathMode.values())
    System.out.println(c);

Returns:

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

valueOf

public static YangXPathParserFactory.MathMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name

NullPointerException - if the argument is null
