public final class ArrayType
Array types represent Java arrays, both primitive and object valued.
Further, Object-valued arrays can have element type of any other
legal JavaType
.
Field Summary | |
---|---|
protected JavaType |
_componentType
Type of elements in the array. |
protected Object |
_emptyArray
We will also keep track of shareable instance of empty array, since it usually needs to be constructed any way; and because it is essentially immutable and thus can be shared. |

Method Summary | |

protected JavaType |
_narrow(Class<?> subclass)
Handling of narrowing conversions for arrays is trickier: for now, it is not even allowed. |
protected String |

construct(JavaType componentType,
Object valueHandler,
Object typeHandler)

JavaType |
containedType(int index)
|
int |
containedTypeCount()
|
String |
containedTypeName(int index)
Not sure what symbolic name is used internally, if any; let's follow naming of Collection types here. |

JavaType |
getContentType()
|
StringBuilder |
getErasedSignature(StringBuilder sb)
Method for accessing signature without generic type information, in form compatible with all versions of JVM, and specifically used for type descriptions when generating byte code. |
StringBuilder |
getGenericSignature(StringBuilder sb)
|
boolean |
hasGenericTypes()
|
boolean |
isAbstract()
For some odd reason, modifiers for array classes would claim they are abstract types. |
boolean |
isArrayType()
|
boolean |
isConcrete()
For some odd reason, modifiers for array classes would claim they are abstract types. |
boolean |
isContainerType()
|
JavaType |
narrowContentsBy(Class<?> contentClass)
For array types, both main type and content type can be modified; but ultimately they are interchangeable. |

widenContentsBy(Class<?> contentClass)
|
ArrayType |
withContentTypeHandler(Object h)
"Copy method" that will construct a new instance that is identical to this instance, except that its content type will have specified type handler assigned. |
ArrayType |
withContentValueHandler(Object h)
"Copy method" that will construct a new instance that is identical to this instance, except that it will have specified content value handler assigned. |
ArrayType |
withTypeHandler(Object h)
"Copy method" that will construct a new instance that is identical to this instance, except that it will have specified type handler assigned. |
ArrayType |
withValueHandler(Object h)
"Copy method" that will construct a new instance that is identical to this instance, except that it will have specified value handler assigned. |
