• All Implemented Interfaces:
Bean, ImmutableBean

public final class CalculationTasks
extends Object
implements ImmutableBean
The tasks that will be used to perform the calculations.

This captures the targets, columns and tasks that define the result grid. Each task can be executed to produce the result. Applications will typically use CalculationRunner or CalculationTaskRunner to execute the tasks.

public static CalculationTasks of(CalculationRules rules,
List<? extends CalculationTarget> targets,
List<Column> columns)
Obtains an instance from a set of targets, columns and rules.

The targets will typically be trades. The columns represent the measures to calculate.

Parameters:
rules - the rules defining how the calculation is performed
targets - the targets for which values of the measures will be calculated
columns - the columns that will be calculated
Returns:
• of

public static CalculationTasks of(List<CalculationTask> tasks,
List<Column> columns)
Obtains an instance from a set of tasks and columns.
Parameters:
tasks - the tasks that perform the calculations
columns - the columns that define the calculations
Returns:
• requirements

public MarketDataRequirements requirements(ReferenceData refData)
Gets the market data that is required to perform the calculations.

This can be used to pass into the market data system to obtain and calibrate data.

Parameters:
refData - the reference data
Returns:
the market data required for all calculations
Throws:
RuntimeException - if unable to obtain the requirements
• toString

public String toString()
Overrides:
toString in class Object
• meta

public static MetaBean meta()
The meta-bean for CalculationTasks.
Returns:
the meta-bean, not null
• metaBean

public MetaBean metaBean()
Specified by:
metaBean in interface Bean
• property

public <R> Property<R> property(String propertyName)
Specified by:
property in interface Bean
• propertyNames

public Set<String> propertyNames()
Specified by:
propertyNames in interface Bean
• getTargets

public List<CalculationTarget> getTargets()
Gets the targets that calculations will be performed on.

The result of the calculations will be a grid where each row is taken from this list.

Returns:
the value of the property, not empty
• getColumns

public List<Column> getColumns()
Gets the columns that will be calculated.

The result of the calculations will be a grid where each column is taken from this list.

Returns:
the value of the property, not empty

public List<CalculationTask> getTasks()
Gets the tasks that perform the individual calculations.

The results can be visualized as a grid, with a row for each target and a column for each measure. Each task can calculate the result for one or more cells in the grid.

Returns:
the value of the property, not empty
• equals

public boolean equals(Object obj)
Overrides:
equals in class Object
• hashCode

public int hashCode()
Overrides:
hashCode in class Object
