public class NumberCachedClass
extends CachedClass

Base class for optimized reflection caching of numeric types. Provides common type coercion logic for primitive and boxed numeric types, as well as BigInteger and BigDecimal.

Constructor Details

NumberCachedClass

public NumberCachedClass(Class klazz,
 ClassInfo classInfo)

Constructs a cached class representation for a numeric class.

Parameters:

klazz - the numeric class to cache

classInfo - the class information associated with this cached class

Method Details

coerceArgument

public Object coerceArgument(Object argument)

Coerces the given argument if it is a Number. Delegates to coerceNumber(java.lang.Object) for specialized conversion logic.

Overrides:

coerceArgument in class CachedClass

Parameters:

argument - the argument to coerce

Returns:

the coerced number or the original argument if not a Number

isAssignableFrom

public boolean isAssignableFrom(Class classToTransformFrom)

Determines if the given class can be transformed to this numeric type. Accepts null, Number subclasses, and primitive numeric types.

Overrides:

isAssignableFrom in class CachedClass

Parameters:

classToTransformFrom - the source class to check

Returns:

true if the class can be transformed to this numeric type, false otherwise
