public interface DataSearchValidator

Interface to specify a FieldExpression Validator.

Add the DataSearchValidator implementation to a SearchDescriptor:

fun personSearchDescriptor(): SearchDescriptor<Person> = SearchDescriptorBuilder.builder<Person>()
         .validators(MyValidator())
         .build()

Method Summary

Modifier and Type	Method	Description
`Boolean`	`supports(FieldExpression fieldExpression)`	Checks if the given FieldExpression is supported by the validator.
`Unit`	`validateSingle(Object value, FieldExpression fieldExpression, DataSearchErrors errors)`	Override this method to validate the given single value related to the FieldExpression.
`Unit`	`validateCollection(Collection<Object> values, FieldExpression fieldExpression, DataSearchErrors errors)`	Override this method to validate the given collection of values related to the FieldExpression.
`Unit`	`validate(Collection<FieldExpression> fieldExpressions, DataSearchErrors errors)`	Validates the given FieldExpressions.

```
 Boolean supports(FieldExpression fieldExpression)
```
    Checks if the given FieldExpression is supported by the validator.
    
    Parameters:
    
    fieldExpression - FieldExpression to check
  - validateSingle
```
 Unit validateSingle(Object value, FieldExpression fieldExpression, DataSearchErrors errors)
```
    Override this method to validate the given single value related to the FieldExpression.
    The given DataSearchErrors instance can be used to report any resulting validation errors.
    
    Parameters:
    
    value - single value to be validated.
    
    fieldExpression - FieldExpression related to the value
    
    errors - DataSearchErrors instance used to report any resulting validation errors
  - validateCollection
```
 Unit validateCollection(Collection<Object> values, FieldExpression fieldExpression, DataSearchErrors errors)
```
    Override this method to validate the given collection of values related to the FieldExpression.
    The default behavior is to iterate over values and call validateSingle for each value.
    The given DataSearchErrors instance can be used to report any resulting validation errors.
    
    Parameters:
    
    values - collection of values to be validated.
    
    fieldExpression - FieldExpression related to the values
    
    errors - DataSearchErrors instance used to report any resulting validation errors
  - validate
```
 Unit validate(Collection<FieldExpression> fieldExpressions, DataSearchErrors errors)
```
    Validates the given FieldExpressions.
    The default behavior:
    Iterate over FieldExpressions,
    Filter the FieldExpressions according to the supports method
    Calls validateCollection if the FieldExpression.value is an instance of Collection, otherwise calls validateSingle.
    This method can be overridden to change the default behavior.
