All Implemented Interfaces:

CalculationParameter, Serializable, org.joda.beans.Bean, org.joda.beans.ImmutableBean
```
public final class TargetTypeCalculationParameter
extends Object
implements CalculationParameter, org.joda.beans.ImmutableBean, Serializable
```
A calculation parameter that selects the parameter based on the type of the target.
This can be used where a CalculationParameter is required, and will select an underlying parameter based on the target type.

public static TargetTypeCalculationParameter of(Map<Class<?>,CalculationParameter> parameters,
                                                CalculationParameter defaultParameter)
```
    Obtains an instance from the specified parameters.
    The map provides a lookup from the CalculationTarget implementation type to the appropriate parameter to use for that target. If a target is requested that is not in the map, the default parameter is used.
    
    Parameters:
    
    parameters - the parameters, keyed by target type
    
    defaultParameter - the default parameter
    
    Returns:
    
    the target aware parameter
  - queryType
```
public Class<? extends CalculationParameter> queryType()
```
    Description copied from interface: CalculationParameter
    
    Gets the type that the parameter will be queried by.
    Parameters can be queried using CalculationParameters.findParameter(Class). This type is the key that callers must use in that method.
    By default, this is just Object.getClass(). It will only differ if the query type is an interface rather than the concrete class.
    
    Specified by:
    
    queryType in interface CalculationParameter
    
    Returns:
    
    the type of the parameter implementation
  - filter
```
public Optional<CalculationParameter> filter(CalculationTarget target,
                                             Measure measure)
```
    Description copied from interface: CalculationParameter
    
    Filters this parameter to the specified target and measure.
    Parameters may apply to all targets and measures or just a subset. The CalculationParameters.filter(CalculationTarget, Measure) method uses this method to filter a complete set of parameters.
    By default, this returns Optional.of(this). If the parameter does not apply to either the target or measure, then optional empty must be returned. If desired, the result can be a different parameter, allowing one parameter to delegate to another when filtered.
    
    Specified by:
    
    filter in interface CalculationParameter
    
    Parameters:
    
    target - the calculation target, such as a trade
    
    measure - the measure to be calculated
    
    Returns:
    
    the parameter appropriate to the target and measure, empty if this parameter does not apply
  - meta
```
public static org.joda.beans.TypedMetaBean<TargetTypeCalculationParameter> meta()
```
    The meta-bean for TargetTypeCalculationParameter.
    
    Returns:
    
    the meta-bean, not null
  - metaBean
```
public org.joda.beans.TypedMetaBean<TargetTypeCalculationParameter> metaBean()
```
    Specified by:
    
    metaBean in interface org.joda.beans.Bean
  - getQueryType
```
public Class<? extends CalculationParameter> getQueryType()
```
    Gets the parameter query type.
    
    Returns:
    
    the value of the property, not null
  - getParameters
```
public ImmutableMap<Class<?>,CalculationParameter> getParameters()
```
    Gets the underlying parameters, keyed by target type.
    
    Returns:
    
    the value of the property, not null
  - getDefaultParameter
```
public CalculationParameter getDefaultParameter()
```
    Gets the default underlying parameter.
    
    Returns:
    
    the value of the property, not null
  - equals

public boolean equals(Object obj)
```
    Overrides:
