public abstract class IntegerType
extends Number
implements NativeMapped

Represents a native integer value, which may have a platform-specific size (e.g. long on unix-based platforms). May optionally indicate an unsigned attribute, such that when a value is extracted into a larger-sized container (e.g. int retrieved via Number.longValue(), the value will be unsigned. Default behavior is signed.

Methodendetails

setValue

public void setValue(long value)

Change the value for this data.

Parameter:

value - value to set

toNative

public Object toNative()

Beschreibung aus Schnittstelle kopiert: NativeMapped

Convert this object into a supported native type.

Angegeben von:

toNative in Schnittstelle NativeMapped

Gibt zurück:

Java representation of the original Java object converted to a native type.

fromNative

public Object fromNative(Object nativeValue,
 FromNativeContext context)

Beschreibung aus Schnittstelle kopiert: NativeMapped

Convert the given native object into its Java representation using the given context.

Angegeben von:

fromNative in Schnittstelle NativeMapped

Parameter:

nativeValue - Java representation of the native type to be converted.

context - Context in which the conversion is taking place.

Gibt zurück:

Converted object.

compare

public static <T extends IntegerType> int compare(T v1,
 T v2)

Compares 2 derived IntegerType values - Note: a null value is considered greater than any non-null one (i.e., null values are "pushed" to the end of a sorted array / list of values)

Typparameter:

T - the derived integer type

Parameter:

v1 - The 1st value

v2 - The 2nd value

Gibt zurück:

0 if values are equal - including if both are null, negative if 1st value less than 2nd one, positive otherwise. Note: the comparison uses the longValue().

compare

public static int compare(IntegerType v1,
 long v2)

Compares a IntegerType value with a long one. Note: if the IntegerType value is null then it is consider greater than any long value.

Parameter:

v1 - The IntegerType value

v2 - The long value

Gibt zurück:

0 if values are equal, negative if 1st value less than 2nd one, positive otherwise. Note: the comparison uses the longValue().
