getEnclosingType
Description copied from interface:IType
Returns the type immediately enclosing this type. If this type is not enclosed, returns null.- Specified by:
getEnclosingType
in interfaceIType
-
getGenericType
Description copied from interface:IType
If this is a parameterized type, returns the generic type this type parameterizes. Otherwise, returns null.- Specified by:
getGenericType
in interfaceIType
-
isFinal
public boolean isFinal()Description copied from interface:IType
True if this type cannot be extended. -
isInterface
public boolean isInterface()Description copied from interface:IType
Returns true if this type is an interface.- Specified by:
isInterface
in interfaceIType
-
isEnum
public boolean isEnum()Description copied from interface:IType
Returns true if this type is an enumeration. -
isParameterizedType
public boolean isParameterizedType()Description copied from interface:IType
Returns true if this ia a Parameterized Type. Note a Parameterzied Type is not the same as a Generic Type. The difference is that a Parameterized Type is a concrete version of a Generic Type. For instance, the class ArrayListis a Generic Type, while the class ArrayList is a Parameterized Type of the the Generic Type ArrayList . - Specified by:
isParameterizedType
in interfaceIType
-
isGenericType
public boolean isGenericType()Description copied from interface:IType
Returns true if this ia a Generic Type.- Specified by:
isGenericType
in interfaceIType
- See Also:
-
getGenericTypeVariables
Description copied from interface:IType
Returns an array of GenericTypeVariables declared with this Generic Type. Otherwise, returns null if this is not a Generic Type.- Specified by:
getGenericTypeVariables
in interfaceIType
-
getParameterizedType
Description copied from interface:IType
Assuming this intrinsic type is a Generic type, return the parameterized type associated with the given list of type parameters. If the type has not been created yet, creates the parameterized type. Successive calls to this method having identical parameter types must return the identical parameterized type.- Specified by:
getParameterizedType
in interfaceIType
- Parameters:
ofType
- The type parameters.- Returns:
- The concrete type associated with the type parameters.
-
getTypeParameters
Description copied from interface:IType
If this is a parameterized type, returns the specific types used to create this type, null otherwies.- Specified by:
getTypeParameters
in interfaceIType
-
isArray
public boolean isArray()Description copied from interface:IType
True if this is an array. -
isPrimitive
public boolean isPrimitive()Description copied from interface:IType
True if this type represents a primitive type e.g., Java int, char, etc.- Specified by:
isPrimitive
in interfaceIType
-
getArrayComponent
public Object getArrayComponent(Object array, int iIndex) throws IllegalArgumentException, ArrayIndexOutOfBoundsException Description copied from interface:IType
Returns the value of the indexed component in the specified array object.- Specified by:
getArrayComponent
in interfaceIType
- Parameters:
array
- An array instance of this intrinsic type.iIndex
- The index of the component to get.- Returns:
- The value of the indexed component in the specified array.
- Throws:
IllegalArgumentException
- If the specified object is not an array.ArrayIndexOutOfBoundsException
- If the specified index argument is negative, or if it is greater than or equal to the length of the specified array
-
setArrayComponent
public void setArrayComponent(Object array, int iIndex, Object value) throws IllegalArgumentException, ArrayIndexOutOfBoundsException Description copied from interface:IType
Sets the value of the indexed component in the specified array object.- Specified by:
setArrayComponent
in interfaceIType
- Parameters:
array
- An array instance of this intrinsic type.iIndex
- The index of the component to set.value
- The new value of the indexed component.- Throws:
IllegalArgumentException
- If the specified object is not an array.ArrayIndexOutOfBoundsException
- If the specified index argument is negative, or if it is greater than or equal to the length of the specified array
-
getArrayLength
Description copied from interface:IType
Returns the length of the specified array object.- Specified by:
getArrayLength
in interfaceIType
- Parameters:
array
- An array instance of this intrinsic type.- Returns:
- The length of the array.
- Throws:
IllegalArgumentException
- If the object argument is not an array.
-
getComponentType
Description copied from interface:IType
If this is an array type, a type representing the component type of the array. Otherwise null.- Specified by:
getComponentType
in interfaceIType
-
isMutable
public boolean isMutable()Description copied from interface:IType
Are intances of this type mutable? Note sometimes it's difficult to determine. For instance, java classes don't contain any information about mutability. In which case we always assume mutable, even when the underlying type may in fact be immutable. E.g., even though java.lang.String is not mutable, its corresponding JavaIntrinsicType will say it is. -
readResolve
Description copied from interface:IType
IType requires this method be implemented to ensure IType instances can be centrally defined and cached.- Specified by:
readResolve
in interfaceIType
- Throws:
ObjectStreamException
-
