Class CollectionLikeType

java.lang.Object
  extended by org.codehaus.jackson.type.JavaType
      extended by org.codehaus.jackson.map.type.TypeBase
          extended by org.codehaus.jackson.map.type.CollectionLikeType
All Implemented Interfaces:
JsonSerializable, JsonSerializableWithType
Direct Known Subclasses:
CollectionType

public class CollectionLikeType
extends TypeBase

Type that represents things that act similar to Collection; but may or may not be instances of that interface. This specifically allows framework to check for configuration and annotation settings used for Map types, and pass these to custom handlers that may be more familiar with actual type.

Since:
1.8

                             Object valueHandler,
                             Object typeHandler)
Method Detail

_narrow

protected JavaType _narrow(Class<?> subclass)
Specified by:
_narrow in class JavaType

narrowContentsBy

public JavaType narrowContentsBy(Class<?> contentClass)
Specified by:
narrowContentsBy in class JavaType

widenContentsBy

public JavaType widenContentsBy(Class<?> contentClass)
Specified by:
widenContentsBy in class JavaType

construct

public static CollectionLikeType construct(Class<?> rawType,
                                           JavaType elemT)

withTypeHandler

public CollectionLikeType withTypeHandler(Object h)
Description copied from class: JavaType
"Copy method" that will construct a new instance that is identical to this instance, except that it will have specified type handler assigned.

Specified by:
withTypeHandler in class JavaType
Returns:
Newly created type instance

withContentTypeHandler

public CollectionLikeType withContentTypeHandler(Object h)
Description copied from class: JavaType
"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.

Specified by:
withContentTypeHandler in class JavaType
Returns:
Newly created type instance

withValueHandler

public CollectionLikeType withValueHandler(Object h)
Overrides:
withValueHandler in class JavaType

withContentValueHandler

public CollectionLikeType withContentValueHandler(Object h)
Overrides:
withContentValueHandler in class JavaType

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.

isCollectionLikeType

public boolean isCollectionLikeType()
Overrides:
isCollectionLikeType in class JavaType
Returns:
True if type is either true Collection type, or something similar (meaning it has at least one type parameter, which describes type of contents)

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)

containedTypeName

public String containedTypeName(int index)
Not sure if we should count on this, but type names for core interfaces use "E" for element type

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)

getErasedSignature

public StringBuilder getErasedSignature(StringBuilder sb)
Description copied from class: JavaType
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.

Specified by:
getErasedSignature in class TypeBase
Parameters:
sb - StringBuilder to append signature to
Returns:
StringBuilder that was passed in; returned to allow call chaining

getGenericSignature

public StringBuilder getGenericSignature(StringBuilder sb)
Specified by:
getGenericSignature in class TypeBase
Parameters:
sb - StringBuilder to append signature to
Returns:
StringBuilder that was passed in; returned to allow call chaining

buildCanonicalName

protected String buildCanonicalName()
Specified by:
buildCanonicalName in class TypeBase

isTrueCollectionType

public boolean isTrueCollectionType()
Method that can be used for checking whether this type is a "real" Collection type; meaning whether it represents a parameterized subtype of Collection or just something that acts like one.

Since:
1.8

equals

public boolean equals(Object o)
Specified by:
equals in class JavaType

toString

public String toString()
Specified by:
toString in class JavaType
