All Implemented Interfaces:

Serializable, Comparable<YangXPathMathMode>

@Beta
public enum YangXPathMathMode
extends Enum<YangXPathMathMode>

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 Summary

Enum Constants

Enum Constant	Description
EXACT	All number expressions are treated as infinite-precision numbers.
IEEE754	All number expressions are treated as double.

Method Summary

Modifier and Type	Method	Description
YangXPathMathSupport	getSupport()	Return YangXPathMathSupport which provides support for the this mode.
static YangXPathMathMode	valueOf(String name)	Returns the enum constant of this type with the specified name.

Enum Constant Detail

IEEE754

public static final YangXPathMathMode 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 YangXPathMathMode 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 YangXPathMathMode[] 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 (YangXPathMathMode c : YangXPathMathMode.values())
    System.out.println(c);

Returns:

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

valueOf

public static YangXPathMathMode 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

getSupport

public YangXPathMathSupport getSupport()

Return YangXPathMathSupport which provides support for the this mode.

Returns:

YangXPathMathSupport supporting this mode.
