org.codehaus.groovy.reflection.stdclasses.DoubleCachedClass

Direct Known Subclasses:

BigDecimalCachedClass

public class DoubleCachedClass
extends NumberCachedClass

Provides optimized reflection caching for double and Double. Coerces numeric arguments to double values, with validation to prevent overflow to infinity. Optionally allows null values for the boxed Double class variant.

Constructor Details

DoubleCachedClass

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

Constructs a cached class representation for the given double class.

Parameters:

klazz - the double class to cache (either double.class or Double.class)

classInfo - the class information associated with this cached class

allowNull - true to allow null values (for Double.class), false for primitive double

Method Details

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 a Double instance, or null is allowed, false otherwise

coerceArgument

public Object coerceArgument(Object argument)

Coerces the given numeric argument to a double value. Validates that BigDecimal conversions do not overflow to infinity.

Overrides:

coerceArgument in class NumberCachedClass

Parameters:

argument - the argument to coerce

Returns:

the argument as a double, or the original argument if not a number

Throws:

IllegalArgumentException - if a BigDecimal conversion results in infinity

isAssignableFrom

public boolean isAssignableFrom(Class classToTransformFrom)

Determines if the given class can be transformed to double/Double. Accepts all numeric types, including integral and big numeric types.

Overrides:

isAssignableFrom in class NumberCachedClass

Parameters:

classToTransformFrom - the source class to check

Returns:

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