Class Extend

java.lang.Object
ru.objectsfill.object_param.Extend
public class Extend extends Object
Per-field parameter override for customizing how individual fields are populated. Allows setting custom collection sizes, value lengths, and mutation functions that target specific fields by name, by class type, or apply globally.

Example: 


 Extend.field("name").addMutationFunction(n -> "Custom").gen()
 Extend.clazz(String.class).valueLength(20).gen()
 Extend.wrapByFunction(obj -> transform(obj)).gen()

      Returns:
      the mutation function, or null if none is set

    • getFieldName

      public String getFieldName()
      Returns the field name used for matching.
      Returns:
      the field name, or null if matching by class type

    • getCollectionSize

      public Integer getCollectionSize()
      Returns the custom collection size for this field.
      Returns:
      the collection size override, or null to use the default

    • getValueLength

      public Integer getValueLength()
      Returns the custom value length for this field.
      Returns:
      the value length override, or null to use the default

    • field

      public static Extend.FillFieldParametersBuilder field(String fieldName)
      Starts building an Extend that targets a specific field by name.
      Parameters:
      fieldName - the name of the field to customize
      Returns:
      a new builder

    • clazz

      public static Extend.FillFieldParametersBuilder clazz(Class<?> clazz)
      Starts building an Extend that targets all fields of a specific class type.
      Parameters:
      clazz - the class type to match fields against
      Returns:
      a new builder

    • wrapByFunction

      public static Extend.FillFieldParametersBuilder wrapByFunction(UnaryOperator<Object> singleChangeFunction)
      Starts building an Extend with a global mutation function applied to every generated value (when no field name or class is specified).
      Parameters:
      singleChangeFunction - the mutation function
      Returns:
      a new builder
