Class ArrayType

          org.codehaus.jackson.map.type.ArrayType

public final class ArrayType
extends TypeBase

Array types represent Java arrays, both primitive and object valued. Further, Object-valued arrays can have element type of any other legal JavaType.

Method Summary

protected JavaType	_narrow(Class<?> subclass) Handling of narrowing conversions for arrays is trickier: for now, it is not even allowed.
protected String	buildCanonicalName()
static ArrayType	construct(JavaType componentType)
JavaType	containedType(int index) Method for accessing definitions of contained ("child") types.
int	containedTypeCount() Method for checking how many contained types this type has.
String	containedTypeName(int index) Not sure what symbolic name is used internally, if any; let's follow naming of Collection types here.
boolean	equals(Object o)
JavaType	getContentType() Method for accessing content type of this type, if type has such a thing: simple types do not, structured types do (like arrays, Collections and Maps)
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.
String	toString()

Method Detail

construct

public static ArrayType construct(JavaType componentType)

buildCanonicalName

protected String buildCanonicalName()

Specified by:

buildCanonicalName in class TypeBase

_narrow

protected JavaType _narrow(Class<?> subclass)

Handling of narrowing conversions for arrays is trickier: for now, it is not even allowed.

Specified by:

_narrow in class JavaType

narrowContentsBy

public JavaType narrowContentsBy(Class<?> contentClass)

For array types, both main type and content type can be modified; but ultimately they are interchangeable.

Specified by:

narrowContentsBy in class JavaType

isArrayType

public boolean isArrayType()

Overrides:

isArrayType in class JavaType

isAbstract

public boolean isAbstract()

For some odd reason, modifiers for array classes would claim they are abstract types. Not so, at least for our purposes.

Overrides:

isAbstract in class JavaType

isConcrete

public boolean isConcrete()

For some odd reason, modifiers for array classes would claim they are abstract types. Not so, at least for our purposes.

Overrides:

isConcrete in class JavaType

containedTypeName

public String containedTypeName(int index)

Not sure what symbolic name is used internally, if any; let's follow naming of Collection types here. Should not really matter since array types have no super types.

Overrides:

containedTypeName in class JavaType

Parameters:

index - Index of contained type to return

Returns:

Contained type at index, or null if no such type exists (no exception thrown)

isContainerType

public boolean isContainerType()

Specified by:

isContainerType in class JavaType

Returns:

True if type represented is a container type; this includes array, Map and Collection types.

getContentType

public JavaType getContentType()

Description copied from class: JavaType

Method for accessing content type of this type, if type has such a thing: simple types do not, structured types do (like arrays, Collections and Maps)

Overrides:

getContentType in class JavaType

containedTypeCount

public int containedTypeCount()

Description copied from class: JavaType

Method for checking how many contained types this type has. Contained types are usually generic types, so that generic Maps have 2 contained types.

Overrides:

containedTypeCount in class JavaType

containedType

public JavaType containedType(int index)

Description copied from class: JavaType

Method for accessing definitions of contained ("child") types.

Overrides:

containedType in class JavaType

Parameters:

index - Index of contained type to return

Returns:

Contained type at index, or null if no such type exists (no exception thrown)

toString

public String toString()

Specified by:

toString in class JavaType

equals

public boolean equals(Object o)

Specified by:

equals in class JavaType
