  • Constructor Details

    • AbstractPrimitiveGenerator

      protected AbstractPrimitiveGenerator()
      Crates a new instance.

      Infers generated values type from the generic type arguments of this instance class. The class must extend AbstractPrimitiveGenerator specifying the generic types.

      Example: 

       class MyLongGenerator
 extends AbstractPrimitiveGenerator<Long> {
     ...
 }

    • AbstractPrimitiveGenerator

      protected AbstractPrimitiveGenerator(@NotNull @NotNull Class<T> valueType)
      Crates a new instance.
      Parameters:
      valueType - The type of generated values

  • Method Details

    • supports

      public boolean supports(@NotNull @NotNull Class<?> type)
      Checks if values of the specified type can be generated by this instance.
      Specified by:
      supports in interface Generator
      Overrides:
      supports in class AbstractTypedGenerator<T>
      Parameters:
      type - The type to check.
      Returns:
      If values of the specified type can be generated.

    • nullableDefaultValue

      public <R> R nullableDefaultValue(@NotNull @NotNull Class<R> type)
      Returns the default value for the specified type allowing null values.

      This method should return null except for native types.

      Specified by:
      nullableDefaultValue in interface Generator
      Overrides:
      nullableDefaultValue in class AbstractGenerator
      Type Parameters:
      R - The requested value type.
      Parameters:
      type - The requested value type.
      Returns:
      The nullable default value for the specified type.

    • randomNull

      public boolean randomNull(@NotNull @NotNull Class<?> type)
      Determines if the value must be null based on the probability of null values.

      Overriding classes can use the type parameter to detect non nullable types (like primitives).

      Overrides:
      randomNull in class AbstractGenerator
      Parameters:
      type - The requested value type
      Returns:
      If the value must be null
