pl.decerto.hyperon.persistence.model.value.Property

pl.decerto.hyperon.persistence.model.value.RefProperty

All Implemented Interfaces:

Iterable<Property>, Handle

public class RefProperty
extends Property

This class represents reference (pointer) to real target Property. Created reference property acts as simple wrapper of target. All methods call on reference will actually invoke methods on target. Reference and target property are of the same type - TypeDef. What is also important, that reference property is equals to target property in the sense of equals and hashCode implementation.

Constructor Detail

RefProperty

public RefProperty(Property target)

Creates reference property, which points to target Property. New created RefProperty will be of the same type, as passed target.

Parameters:

target - property, to which created reference property points

Method Detail

getId

public long getId()

Specified by:

getId in class Property

Returns:

target's id

deepcopy

public Property deepcopy(boolean resetIds)

Creates new instance of RefProperty with same target instance.

Specified by:

deepcopy in class Property

Parameters:

resetIds - this flag doesn't apply here

Returns:

new reference property instance

Property.deepcopy()

print

public void print(StringBuilder sb,
                  int level,
                  String prefix,
                  String suffix)

Adds to sb formatted String, specific for RefProperty, which looks like:

  * [REF] cover1  (Cover#1003  @25658)
  - [REF] cover2  (Cover#1004  @95658)
 

Specified by:

print in class Property

Parameters:

sb - StringBuilder containing data to print

level - level used to indentation

prefix - value to used as prefix

suffix - value to used as suffix

set

public void set(Object value)

Sets new value of this property.
Here it means that this reference will be removed from property tree, and new value will be used instead.

Specified by:

set in interface Handle

Overrides:

set in class Property

Parameters:

value - new reference

isRef

public boolean isRef()

Is property a reference type.

Returns:

true

getRefTarget

public Property getRefTarget()

Overrides:

getRefTarget in class Property

Returns:

target property

getRefCount

public int getRefCount()

Number of nodes referencing target's property.

Specified by:

getRefCount in interface Handle

Overrides:

getRefCount in class Property

number of references

find

public Property find(long id)

Find child property in the target.

Parameters:

id - child id

Returns:

property within target

has

public boolean has(String path)

Checks if target property has element of given path.

Parameters:

path - of element to be checked

Returns:

true if target has element, or false otherwise

asEntity

public EntityProperty asEntity()

Description copied from class: Property

Specified by:

asEntity in interface Handle

Overrides:

asEntity in class Property

Returns:

target as EntityProperty

getElementType
