final class ArrayType extends ReferenceType
Represents an array type.
Comparing ArrayTypes
To facilitate comparisons of (array) types, each array type is represented
at any given time, by exactly one instance of ArrayType.
General Information
From the JVM specification
An array type consists of a component type with a single dimension (whose length is not given by the type). The component type of an array type may itself be an array type. If, starting from any array type, one considers its component type, and then (if that is also an array type) the component type of that type, and so on, eventually one must reach a component type that is not an array type; this is called the element type of the array type. The element type of an array type is necessarily either a primitive type, or a class type, or an interface type.

- def compare(that: Type): Int
Compares this type with the given type.
Compares this type with the given type.
Comparison of types is implemented by comparing the associated ids. I.e., the result of the comparison of two types is not stable across multiple runs of OPAL.

The number of dimensions of this array.
The number of dimensions of this array. E.g. "Object[]" has one dimension and "Object[][]" has two dimensions.
- def drop(dimensions: Int): FieldType
Returns the component type of this array type after dropping the given number of dimensions.
Returns the component type of this array type after dropping the given number of dimensions. E.g., if dimensions is

The number of dimensions to drop. This values has to be equal or smaller than the number of dimensions of this array.
- def elementType: FieldType

This is generally only useful in very special cases and – to be meaningful at all – it is necessary that the class path used for running the static analysis also contains the classes that are analyzed. This is (often) only the case for the JDK.
However, one example where this is useful is the creation of a real object of a specific type and to use that object when a method is called on that object. This avoids the reimplementation of the respective logic as part of the analysis. For example, if you want to get the
Stringthat is created by a specificStringBufferit is possible to implement the API of StringBuffer as part of your analysis or (probably more efficient) to just create an instance of aStringBufferobject and to redirect every call to the real object. In this case only some general logic is required to redirect calls and to convert the values between the representation used by the analysis and the representation required by the called method. - def toString(): String
