Description
| Class Summary | |
| ArrayBase | Base class for type-specific growable array classes with any type of values (including primitive types). |
| ByteArray | Growable byte array with type specific access methods. |
| CharArray | Growable char array with type specific access methods. |
| DoubleArray | Growable double array with type specific access methods. |
| IntArray | Growable int array with type specific access methods. |
| ObjectArray | Growable Object array with type specific access methods. |
| StringArray | Growable String array with type specific access methods. |
Type-specific growable array collection classes. The classes in this
package are basically equivalent to type-specific versions of the
standard java.util.Vector or newer
java.util.ArrayList class. They support a few added
methods (including direct conversion to a typed array with
toArray()) and some minor interface differences. The standard
public access methods in these classes are as follows:
| Method Signature | From |
int add(type) | implementation class |
void add(int, type) | implementation class |
void clear() | ArrayBase |
Object clone() | implementation class |
void ensureCapacity(int) | GrowableBase |
type get(int) | implementation class |
void remove(int) | ArrayBase |
void remove(int, int) | ArrayBase |
void set(int, type) | implementation class |
void setSize(int) | ArrayBase |
int size() | ArrayBase |
type[] toArray() | implementation class |
type[] toArray(int, int) | implementation class |
The ObjectArray class also provides a pair of toArray
methods which allow the base element type of the array to be specified as
something other than Object.
As with ArrayList, the access methods are
unsynchronized for best performance. The user program must implement
appropriate locking if multiple threads need to access an
instance of these classes while that instance may be modified.
Collections of a primitive type and of a specific object type
are both supported. All variations derive directly from the
ArrayBase base class. To define a growable array of a
new type, generally you can use one of the existing classes as a base
and do a text substitution of the type names.
For instance, to define a growable array of instances of
Thread just copy StringArray.java
to a new file named ThreadArray.java, then do a global
text substitution of "Thread" for "String" in the new file.
Primitive types are only slightly more complicated. byte and
char versions are included, and short can be done
using one of these as a base and just substituting the type name. The other primitive
types, which are not promoted to int in
expressions, can use the implementation for double as a base.
