Method Detail

isIntegral

public boolean isIntegral()

Description copied from interface: JsonNumber

Returns true if this JSON number is a integral number. This method semantics are defined using bigDecimalValue().scale(). If the scale is zero, then it is considered integral type. This integral type information can be used to invoke an appropriate accessor method to obtain a numeric value as in the following example:

 
 JsonNumber num = ...
 if (num.isIntegral()) {
     num.longValue();     // or other methods to get integral value
 } else {
     num.doubleValue();   // or other methods to get decimal number value
 }
 
 

Specified by:

isIntegral in interface JsonNumber

Overrides:

isIntegral in class JsonNumberImpl

Returns:

true if this number is a integral number, otherwise false

longValue

public long longValue()

Description copied from interface: JsonNumber

Returns this JSON number as a long. Note that this conversion can lose information about the overall magnitude and precision of the number value as well as return a result with the opposite sign.

Specified by:

longValue in interface JsonNumber

Overrides:

longValue in class JsonNumberImpl

Returns:

a long representation of the JSON number.

See Also:

BigDecimal.longValue()

longValueExact

public long longValueExact()

Description copied from interface: JsonNumber

Returns this JSON number as a long.

Specified by:

longValueExact in interface JsonNumber

Overrides:

longValueExact in class JsonNumberImpl

Returns:

a long representation of the JSON number

See Also:

BigDecimal.longValueExact()

doubleValue

public double doubleValue()

Description copied from interface: JsonNumber

Returns this JSON number as a double. This is a a convenience method for bigDecimalValue().doubleValue(). Note that this conversion can lose information about the overall magnitude and precision of the number value as well as return a result with the opposite sign.

Specified by:

doubleValue in interface JsonNumber

Overrides:

doubleValue in class JsonNumberImpl

Returns:

a double representation of the JSON number

See Also:

BigDecimal.doubleValue()

bigDecimalValue

public java.math.BigDecimal bigDecimalValue()

Description copied from interface: JsonNumber

Returns this JSON number as a BigDecimal object.

Returns:

a BigDecimal representation of the JSON number

toString

public java.lang.String toString()

Description copied from interface: JsonNumber

Returns a JSON text representation of the JSON number. The representation is equivalent to BigDecimal.toString().

Specified by:

toString in interface JsonNumber

Specified by:

toString in interface JsonValue

Overrides:

toString in class JsonNumberImpl

Returns:

JSON text representation of the number
