Class LongValue

java.lang.Object
  org.apache.wicket.util.value.LongValue

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<LongValue>

Direct Known Subclasses:

Bytes, Duration, Time, TimeOfDay

public class LongValue
extends java.lang.Object
implements java.lang.Comparable<LongValue>, java.io.Serializable

A base class based on the Java long primitive for value classes that want to implement standard operations on that value without the pain of aggregating a Long object.

Method Detail

compareTo

public final int compareTo(LongValue that)

Compares this Object to a given Object.

Specified by:

compareTo in interface java.lang.Comparable<LongValue>

Parameters:

that - the Object to compare with

Returns:

0 if equal, -1 if less than the given Object's value, or 1 if greater than given Object's value

equals

public final boolean equals(java.lang.Object that)

Tests for equality.

Overrides:

equals in class java.lang.Object

Parameters:

that - the Object to compare with

Returns:

true if this Object's value is equal to the given Object's value

greaterThan

public final boolean greaterThan(long value)

Compares this LongValue with a primitive long value.

Parameters:

value - the long value to compare with

Returns:

true if this LongValue is greater than the given long value

greaterThanOrEqual

public final boolean greaterThanOrEqual(long value)

Compares this LongValue with a primitive long value.

Parameters:

value - the long value to compare with

Returns:

true if this LongValue is greater than or equal to the given long value

greaterThan

public final boolean greaterThan(LongValue that)

Compares this LongValue with another LongValue.

Parameters:

that - the LongValue to compare with

Returns:

true if this LongValue is greater than the given LongValue

greaterThanOrEqual

public final boolean greaterThanOrEqual(LongValue that)

true if this LongValue is greater than or equal to the given LongValue

hashCode

public final int hashCode()

Returns the hash code for this Object.

Overrides:

hashCode in class java.lang.Object

Returns:

hash code for this Object

lessThan

public final boolean lessThan(long that)

Compares this LongValue with a primitive long value.

Parameters:

that - the long value to compare with

Returns:

true if this LongValue is less than the given long value

lessThanOrEqual

public final boolean lessThanOrEqual(long that)

Compares this LongValue with a primitive long value.

Parameters:

that - the long value to compare with

Converts this LongValue to a String.

Overrides:

toString in class java.lang.Object

Returns:

a String representation of this LongValue

max

public static <T extends LongValue> T max(T lhs,
                                          T rhs)

Returns the max of the two long values.

Type Parameters:

T -

Parameters:

lhs -

rhs -

Returns:

max value

Throws:

java.lang.IllegalArgumentException - if either argument is null

maxNullSafe

public static <T extends LongValue> T maxNullSafe(T lhs,
