public class IntegerCachedClass
extends NumberCachedClass

Provides optimized reflection caching for int and Integer. Coerces numeric arguments to int values for type-safe method invocation. Optionally allows null values for the boxed Integer class variant.

Constructor Details

IntegerCachedClass

public IntegerCachedClass(Class klazz,
 ClassInfo classInfo,
 boolean allowNull)

Constructs a cached class representation for the given integer class.

Parameters:

klazz - the integer class to cache (either int.class or Integer.class)

classInfo - the class information associated with this cached class

allowNull - true to allow null values (for Integer.class), false for primitive int

Method Details

coerceArgument

public Object coerceArgument(Object argument)

Coerces the given numeric argument to an int value.

Overrides:

coerceArgument in class NumberCachedClass

Parameters:

argument - the argument to coerce

Returns:

the argument as an int, or the original argument if not a number

isDirectlyAssignable

public boolean isDirectlyAssignable(Object argument)

Checks if the given argument is directly assignable without type conversion.

Overrides:

isDirectlyAssignable in class CachedClass

Parameters:

argument - the argument to check

Returns:

true if the argument is an Integer instance, or null is allowed, false otherwise

isAssignableFrom

public boolean isAssignableFrom(Class classToTransformFrom)

Determines if the given class can be transformed to int/Integer. Accepts integral types, boxed integral types, and BigInteger.

Overrides:

isAssignableFrom in class NumberCachedClass

Parameters:

classToTransformFrom - the source class to check

Returns:

true if the class can be transformed to int, false otherwise
