Class ValueAdjustment

java.lang.Object

com.opengamma.strata.basics.value.ValueAdjustment

All Implemented Interfaces:

Serializable, org.joda.beans.Bean, org.joda.beans.ImmutableBean

public final class ValueAdjustment
extends Object
implements org.joda.beans.ImmutableBean, Serializable

An adjustment to a value, describing how to change one value into another.

A base value, represented as a double, can be transformed into another value by specifying the result (absolute) or the calculation (relative).

Type	baseValue	modifyingValue	Calculation
Replace	200	220	result = modifyingValue = 220
DeltaAmount	200	20	result = baseValue + modifyingValue = (200 + 20) = 220
DeltaMultiplier	200	0.1	result = baseValue + baseValue * modifyingValue = (200 + 200 * 0.1) = 220
Multiplier	200	1.1	result = baseValue * modifyingValue = (200 * 1.1) = 220

Field Detail

NONE

public static final ValueAdjustment NONE

An instance that makes no adjustment to the value.

Method Detail

ofReplace

public static ValueAdjustment ofReplace(double replacementValue)

Obtains an instance that replaces the base value.

The base value is ignored when calculating the result.

Parameters:

replacementValue - the replacement value to use as the result of the adjustment

Returns:

the adjustment, capturing the replacement value

ofDeltaAmount

public static ValueAdjustment ofDeltaAmount(double deltaAmount)

Obtains an instance specifying an amount to add to the base value.

The result will be (baseValue + deltaAmount).

Parameters:

deltaAmount - the amount to be added to the base value

Returns:

the adjustment, capturing the delta amount

ofDeltaMultiplier

public static ValueAdjustment ofDeltaMultiplier(double deltaMultiplier)

Obtains an instance specifying a multiplication factor, adding it to the base value.

The result will be (baseValue + baseValue * modifyingValue).

Parameters:

deltaMultiplier - the multiplication factor to apply to the base amount with the result added to the base amount

Returns:

the adjustment, capturing the delta multiplier

ofMultiplier

public static ValueAdjustment ofMultiplier(double multiplier)

Obtains an instance specifying a multiplication factor to apply to the base value.

The result will be (baseValue * modifyingValue).

Parameters:

multiplier - the multiplication factor to apply to the base amount

Returns:

the adjustment

toString

public String toString()

Overrides:

toString in class Object

adjust

public double adjust(double baseValue)

Adjusts the base value based on the criteria of this adjustment.

For example, if this adjustment represents a 10% decrease, then the result will be the base value minus 10%.

Parameters:

baseValue - the base, or previous, value to be adjusted

Returns:

the calculated result

meta

public static ValueAdjustment.Meta meta()

The meta-bean for ValueAdjustment.

Returns:

the meta-bean, not null

metaBean

public ValueAdjustment.Meta metaBean()

Specified by:

metaBean in interface org.joda.beans.Bean

getModifyingValue

public double getModifyingValue()

Gets the value used to modify the base value. This value is given meaning by the associated type.

Returns:

the value of the property

getType

public ValueAdjustmentType getType()

Gets the type of adjustment to make.

Returns:

the value of the property, not null

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
