public class PrimitiveUtils

extends java.lang.Object

Provides utilities for working with primitives. The getDefaultPrimitiveValue() method generates default return values for primitives. The getPrimitiveTypeForWrapperClass method converts a primitive wrapper class (such as Integer.class) into a primitive class (such as int.class).

Method Detail

isAssignableToPrimitiveWrapper

public boolean isAssignableToPrimitiveWrapper(java.lang.Class type)

Returns true if the specified type is assignable to any primitive type.

Parameters:

type - the type to check for assignability to a primitive type

Returns:

Returns true if the specified type is assignable to any primitive type

getDefaultPrimitiveValue

public java.lang.Object getDefaultPrimitiveValue(java.lang.Class type)

Generate default return values for specified primitive type.

Parameters:

type - a Class object representing a primitive

Returns:

the default value for the primitive

Throws:

java.lang.IllegalArgumentException - if the type is not a primitive

getPrimitiveTypeForWrapperClass

public java.lang.Class getPrimitiveTypeForWrapperClass(java.lang.Class primitiveWrapperType)

When passed a primitive wrapper type (such as Integer.class), returns the corresponding primitive type (such as int.class).

Parameters:

primitiveWrapperType - The primitive wrapper class to convert to a primitive class

Returns:

the primitive class corresponding to the primitive wrapper class

Throws:

java.lang.IllegalArgumentException - if the specified type is not one of the eight primitive wrapper types
