Imports
java.lang.reflect.Array, tools.jackson.databind.JavaType
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

Modifier and TypeField and Description
protected final JavaType
_componentType

Type of elements in the array.

protected final 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.

public boolean
equals(Object o)

Implements abstract tools.jackson.databind.JavaType.equals.

Indicates whether some other object is "equal to" this one.

public JavaType
getContentType()

Overrides tools.jackson.databind.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)

public Object
getContentTypeHandler()

Overrides tools.jackson.databind.JavaType.getContentTypeHandler.

Internal accessor that should not be used by any code outside of jackson-databind: only used internally by databind.

public Object
getContentValueHandler()

Overrides tools.jackson.databind.JavaType.getContentValueHandler.

Internal accessor that should not be used by any code outside of jackson-databind: only used internally by databind.

public Object[]
getEmptyArray()

public StringBuilder
getErasedSignature(StringBuilder sb)

Implements abstract tools.jackson.databind.type.TypeBase.getErasedSignature.

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.

public StringBuilder
getGenericSignature(StringBuilder sb)

Implements abstract tools.jackson.databind.type.TypeBase.getGenericSignature.

public boolean
hasGenericTypes()

Overrides tools.jackson.databind.JavaType.hasGenericTypes.

Method that can be used to find out if the type directly declares generic parameters (for its direct super-class and/or super-interfaces).

public boolean
hasHandlers()

Overrides tools.jackson.databind.JavaType.hasHandlers.

Helper method that checks whether this type, or its (optional) key or content type has getValueHandler or getTypeHandler(); that is, are there any non-standard handlers associated with this type object.

public boolean
isAbstract()

Overrides tools.jackson.databind.JavaType.isAbstract.

For some odd reason, modifiers for array classes would claim they are abstract types.

public boolean
isArrayType()

Overrides tools.jackson.databind.JavaType.isArrayType.

public boolean
isConcrete()

Overrides tools.jackson.databind.JavaType.isConcrete.

For some odd reason, modifiers for array classes would claim they are abstract types.

public JavaType
refine(Class<?> contentClass, TypeBindings bindings, JavaType superClass, JavaType[] superInterfaces)

Implements abstract tools.jackson.databind.JavaType.refine.

Mutant factory method that will try to create and return a sub-type instance for known parameterized types; for other types will return `null` to indicate that no just refinement makes necessary sense, without trying to detect special status through implemented interfaces.

public String
toString()

Implements abstract tools.jackson.databind.JavaType.toString.

Returns a string representation of the object.

public JavaType
withContentType(JavaType contentType)

Implements abstract tools.jackson.databind.JavaType.withContentType.

Mutant factory method that may be called on structured types that have a so-called content type (element of arrays, value type of Maps, referenced type of referential types), and will construct a new instance that is identical to this instance, except that it has specified content type, instead of current one.

public ArrayType
withContentTypeHandler(Object h)

Implements abstract tools.jackson.databind.JavaType.withContentTypeHandler.

Internal method that should not be used by any code outside of jackson-databind: only used internally by databind.

withStaticTyping()

Implements abstract tools.jackson.databind.JavaType.withStaticTyping.

Method that can be called to get a type instance that indicates that values of the type should be handled using "static typing" for purposes of serialization (as opposed to "dynamic" aka runtime typing): meaning that no runtime information is needed for determining serializers to use.

public ArrayType
withTypeHandler(Object h)

Implements abstract tools.jackson.databind.JavaType.withTypeHandler.

Internal method that should not be used by any code outside of jackson-databind: only used internally by databind.

public boolean equals(Object o)

Implements abstract tools.jackson.databind.JavaType.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Mutant factory method that may be called on structured types that have a so-called content type (element of arrays, value type of Maps, referenced type of referential types), and will construct a new instance that is identical to this instance, except that it has specified content type, instead of current one. If content type is already set to given type, this is returned. If type does not have a content type (which is the case with SimpleType), IllegalArgumentException will be thrown.

Method that can be called to get a type instance that indicates that values of the type should be handled using "static typing" for purposes of serialization (as opposed to "dynamic" aka runtime typing): meaning that no runtime information is needed for determining serializers to use.
