Class ShortTypeHandling

java.lang.Object
org.codehaus.groovy.runtime.typehandling.ShortTypeHandling
public class ShortTypeHandling extends Object
High-performance type casting and conversion utilities.

Provides fast-path type conversions for common cases. These methods are designed to avoid dependency on the Groovy runtime and should be used directly only when the type constraints documented in each method are met.

For general-purpose type coercion, use DefaultTypeTransformation instead.

    • castToClass

      public static Class castToClass(Object object)
      Casts an object to a Class object.

      Accepts Class objects directly, or a string representation of a class name which is loaded via Class.forName.

      Parameters:
      object - a Class object or string class name
      Returns:
      the Class object, or null if input is null
      Throws:
      GroovyCastException - if the object is not a Class or valid class name

    • castToString

      public static String castToString(Object object)
      Casts an object to a String representation.

      Arrays are converted using Arrays.toString format. Primitive arrays receive special handling to show element values. Other objects use their standard toString() method.

      Parameters:
      object - any object (may be null)
      Returns:
      string representation, or null if input is null

    • castToEnum

      public static Enum castToEnum(Object object, Class<? extends Enum> type)
      Casts an object to an Enum value of the specified type.

      Note: This method requires that the supplied enum is not fitting a Collection case for casting.

      Accepts Enum objects already of the correct type, or a String/GString representation of the enum constant name.

      Parameters:
      object - an enum value, or a string enum constant name
      type - the target enum class
      Returns:
      the Enum value, or null if input is null
      Throws:
      GroovyCastException - if the object cannot be converted to the enum type

    • castToChar

      public static Character castToChar(Object object)
      Casts an object to a char value (Character wrapper).

      Accepts Character objects, Numbers (converted via intValue), or Strings of length 1.

      Parameters:
      object - a Character, Number, or single-character String
      Returns:
      a Character with the coerced value, or null if input is null
      Throws:
      GroovyCastException - if the object cannot be converted to char
