getAncestor

public @Nullable MetaClass getAncestor()

Description copied from interface: MetaClass

Immediate ancestor of the object, or null if there is no one.

Specified by:

getAncestor in interface MetaClass

getAncestors

public List<MetaClass> getAncestors()

Description copied from interface: MetaClass

All ancestors of the metaclass, in order going up from the immediate ancestor.

Specified by:

getAncestors in interface MetaClass

getDescendants

public Collection<MetaClass> getDescendants()

Description copied from interface: MetaClass

All descendants of the metaclass, recursively. Order is undefined.

Specified by:

getDescendants in interface MetaClass

getSession

public Session getSession()

Specified by:

getSession in interface MetaClass

Returns:

containing MetaModel instance. Null signifies a temporary metaclass, not associated with an entity class.

getJavaClass

public <T> Class<T> getJavaClass()

Specified by:

getJavaClass in interface MetaClass

Returns:

corresponding Java class

findProperty

public MetaProperty findProperty(String name)

Description copied from interface: MetaClass

Get MetaProperty by its name.

Specified by:

findProperty in interface MetaClass

Returns:

MetaProperty instance, or null if no such property found

getProperty

public MetaProperty getProperty(String name)

Description copied from interface: MetaClass

Get MetaProperty by its name.

Specified by:

getProperty in interface MetaClass

Returns:

MetaProperty instance. Throws exception if not found.

getPropertyPath

public MetaPropertyPath getPropertyPath(String propertyPath)

Description copied from interface: MetaClass

Returns MetaPropertyPath object, representing path to the property from the current class Note that this method don't take into account extensions(e.g. Dynamic Attributes add-on) and it returns null in case of not static attributes(attributes from extension). For getting all attributes (including attributes from extensions) use MetadataTools.resolveMetaPropertyPath(MetaClass, String) or MetadataTools.resolveMetaPropertyPathOrNull(MetaClass, String) methods.

Specified by:

getPropertyPath in interface MetaClass

Parameters:

propertyPath - dot-separated string

Returns:

MetaPropertyPath instance, or null if the input parameter doesn't represent a valid path.

getOwnProperties

public Collection<MetaProperty> getOwnProperties()

Specified by:

getOwnProperties in interface MetaClass

Returns:

collection of meta properties directly owned by this metaclass.

getProperties

public Collection<MetaProperty> getProperties()

Specified by:

getProperties in interface MetaClass

Returns:

collection of meta properties owned by this metaclass and all its ancestors.

getStore

public Store getStore()

Specified by:

getStore in interface MetaClass

Returns:

store of this entity

setStore

public void setStore(Store store)

toString

public String toString()

Overrides:

toString in class Object

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable
