Class BeanPropertyDefinition

  • java.lang.Object
    • com.fasterxml.jackson.databind.introspect.BeanPropertyDefinition
  • All Implemented Interfaces:
    Named
    Direct Known Subclasses:
    POJOPropertyBuilder, SimpleBeanPropertyDefinition

    public abstract class BeanPropertyDefinition
extends Object
implements Named
    Simple value classes that contain definitions of properties, used during introspection of properties to use for serialization and deserialization purposes. These instances are created before actual BeanProperty instances are created, i.e. they are used earlier in the process flow, and are typically use to construct actual BeanProperty instances.

    • Constructor Detail

      • BeanPropertyDefinition

        public BeanPropertyDefinition()

    • Method Detail

      • withName

        public abstract BeanPropertyDefinition withName(PropertyName newName)
        Method that can be used to create a definition with same settings as this one, but with different (external) name; that is, one for which getName() would return newName.
        Since:
        2.3

      • withSimpleName

        public abstract BeanPropertyDefinition withSimpleName(String newSimpleName)
        Alternate "mutant factory" that will only change simple name, but leave other optional parts (like namespace) as is.
        Since:
        2.3

      • getName

        public abstract String getName()
        Accessor for name used for external representation (in JSON).
        Specified by:
        getName in interface Named

      • hasName

        public boolean hasName(PropertyName name)
        Since:
        2.6

      • getInternalName

        public abstract String getInternalName()
        Accessor that can be used to determine implicit name from underlying element(s) before possible renaming. This is the "internal" name derived from accessor ("x" from "getX"), and is not based on annotations or naming strategy.

      • getWrapperName

        public abstract PropertyName getWrapperName()
        Accessor for finding wrapper name to use for property (if any).
        Since:
        2.2

      • getMetadata

        public abstract PropertyMetadata getMetadata()
        Method for accessing additional metadata. NOTE: will never return null, so de-referencing return value is safe.
        Since:
        2.3

      • isExplicitlyIncluded

        public abstract boolean isExplicitlyIncluded()
        Accessor that can be called to check whether property was included due to an explicit marker (usually annotation), or just by naming convention.
        Returns:
        True if property was explicitly included (usually by having one of components being annotated); false if inclusion was purely due to naming or visibility definitions (that is, implicit)

      • isExplicitlyNamed

        public boolean isExplicitlyNamed()
        Accessor that can be called to check whether property name was due to an explicit marker (usually annotation), or just by naming convention or use of "use-default-name" marker (annotation).

        Note that entries that return true from this method will always return true for isExplicitlyIncluded(), but not necessarily vice versa.

        Since:
        2.4

      • couldDeserialize

        public boolean couldDeserialize()

      • couldSerialize

        public boolean couldSerialize()

      • hasGetter

        public abstract boolean hasGetter()

      • hasSetter

        public abstract boolean hasSetter()

      • hasField

        public abstract boolean hasField()

      • hasConstructorParameter

        public abstract boolean hasConstructorParameter()

      • getConstructorParameters

        public Iterator<AnnotatedParameter> getConstructorParameters()
        Additional method that may be called instead of getConstructorParameter() to get access to all constructor parameters, not just the highest priority one.
        Since:
        2.5

      • getAccessor

        public abstract AnnotatedMember getAccessor()
        Method used to find accessor (getter, field to access) to use for accessing value of the property. Null if no such member exists.

      • getMutator

        public abstract AnnotatedMember getMutator()
        Method used to find mutator (constructor parameter, setter, field) to use for changing value of the property. Null if no such member exists.

      • getNonConstructorMutator

        public abstract AnnotatedMember getNonConstructorMutator()
        Since:
        2.3

      • getPrimaryMember

        public abstract AnnotatedMember getPrimaryMember()
        Method used to find the property member (getter, setter, field) that has the highest precedence in current context (getter method when serializing, if available, and so forth), if any.

        Note: abstract since 2.5

        Since:
        2.1

      • findViews

        public Class<?>[] findViews()
        Method used to find View-inclusion definitions for the property.

      • isTypeId

        public boolean isTypeId()
        Method used to check whether this logical property has a marker to indicate it should be used as the type id for polymorphic type handling.

      • findObjectIdInfo

        public ObjectIdInfo findObjectIdInfo()
        Method used to check whether this logical property indicates that value POJOs should be written using additional Object Identifier (or, when multiple references exist, all but first AS Object Identifier).

      • isRequired

        public boolean isRequired()
        Method used to check if this property is expected to have a value; and if none found, should either be considered invalid (and most likely fail deserialization), or handled by other means (by providing default value)

      • findInclusion

        public JsonInclude.Value findInclusion()
        Method used to check if this property has specific inclusion override associated with it or not.
        Since:
        2.5
