Class JsonNumber

java.lang.Object

io.helidon.json.JsonValue

io.helidon.json.JsonNumber

public final class JsonNumber
extends JsonValue

Represents a JSON number value. Equality follows BigDecimal.equals(Object), including its scale-sensitive semantics.

Method Details

create

public static JsonNumber create(BigDecimal bigDecimalValue)

Create a JsonNumber from a BigDecimal value.

Parameters:

bigDecimalValue - the BigDecimal value

Returns:

a new JsonNumber

create

public static JsonNumber create(double doubleValue)

Create a JsonNumber from a double value.

Parameters:

doubleValue - the double value

Returns:

a new JsonNumber

create

public static JsonNumber create(long longValue)

Create a JsonNumber from a long value.

Parameters:

longValue - the long value

Returns:

a new JsonNumber

doubleValue

public double doubleValue()

Return the double value of this JsonNumber. This conversion may lose precision or return an infinity if the magnitude is too large.

Returns:

the double value

See Also:

• BigDecimal.doubleValue()

byteValue

public byte byteValue()

Return the byte value of this JsonNumber. Any fractional part is discarded. If the resulting integer does not fit, only the low-order 8 bits are returned, so the result may have the opposite sign.

Returns:

the byte value

See Also:

• Number.byteValue()

shortValue

public short shortValue()

Return the short value of this JsonNumber. Any fractional part is discarded. If the resulting integer does not fit, only the low-order 16 bits are returned, so the result may have the opposite sign.

Returns:

the short value

See Also:

• Number.shortValue()

intValue

public int intValue()

Return the int value of this JsonNumber. Any fractional part is discarded. If the resulting integer does not fit, only the low-order 32 bits are returned, so the result may have the opposite sign.

Returns:

the int value

See Also:

• BigDecimal.intValue()

longValue

public long longValue()

Return the long value of this JsonNumber. Any fractional part is discarded. If the resulting integer does not fit, only the low-order 64 bits are returned, so the result may have the opposite sign.

Returns:

the long value

See Also:

• BigDecimal.longValue()

floatValue

public float floatValue()

Return the float value of this JsonNumber. This conversion may lose precision or return an infinity if the magnitude is too large.

Returns:

the float value

See Also:

• BigDecimal.floatValue()

bigIntegerValue

public BigInteger bigIntegerValue()

Return the BigInteger value of this JsonNumber. Any fractional part is discarded.

For a nonzero value with a negative scale, a conversion may introduce at most 4,096 trailing decimal digits. Numbers originating from the same parsed JSON document also share a cumulative budget of 65,536 such digits; every invocation consumes that document budget. Programmatically created numbers have only the per-conversion limit.

Returns:

the BigInteger value

Throws:

JsonException - if the conversion exceeds the per-value or parsed-document expansion budget

See Also:

• BigDecimal.toBigInteger()

bigDecimalValue

public BigDecimal bigDecimalValue()

Return the BigDecimal value of this JsonNumber.

Returns:

the BigDecimal value

type

public JsonValueType type()

Description copied from class: JsonValue

Return the type of this JSON value.

Specified by:

type in class JsonValue

Returns:

the JsonValueType of this value

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toJson

public void toJson(JsonGenerator generator)

Description copied from class: JsonValue

Write this JSON value to the provided generator.

Specified by:

toJson in class JsonValue

Parameters:

generator - the generator to write to
