Constructor Detail

BeanPropertyAssoc

public BeanPropertyAssoc(BeanDescriptorMap owner,
                 BeanDescriptor<?> descriptor,
                 DeployBeanPropertyAssoc<T> deploy)

Construct the property.

Method Detail

initialise

public void initialise()

Initialise post construction.

Overrides:

initialise in class BeanProperty

createElPropertyValue

protected ElPropertyValue createElPropertyValue(String propName,
                                    String remainder,
                                    ElPropertyChainBuilder chain,
                                    boolean propertyDeploy)

Create a ElPropertyValue for a *ToOne or *ToMany.

addJoin

public boolean addJoin(boolean forceOuterJoin,
              String prefix,
              DbSqlContext ctx)

Add table join with table alias based on prefix.

addJoin

public boolean addJoin(boolean forceOuterJoin,
              String a1,
              String a2,
              DbSqlContext ctx)

Add table join with explicit table alias.

addInnerJoin

public void addInnerJoin(String a1,
                String a2,
                DbSqlContext ctx)

Add table join with explicit table alias.

isScalar

public boolean isScalar()

Return false.

Overrides:

isScalar in class BeanProperty

getMappedBy

public String getMappedBy()

Return the mappedBy property. This will be null on the owning side.

getTargetIdProperty

public String getTargetIdProperty()

Return the Id property of the target entity type.

This will return null for multiple Id properties.

getTargetDescriptor

public BeanDescriptor<T> getTargetDescriptor()

Return the BeanDescriptor of the target.

isSaveRecurseSkippable

public boolean isSaveRecurseSkippable(Object bean)

isSaveRecurseSkippable

public boolean isSaveRecurseSkippable()

Return true if save can be skipped for unmodified bean(s) of this property.

That is, if a bean of this property is unmodified we don't need to saveRecurse because none of its associated beans have cascade save set to true.

isDeleteRecurseSkippable

public boolean isDeleteRecurseSkippable()

Similar to isSaveRecurseSkippable but in terms of delete.

hasId

public boolean hasId(Object bean)

Return true if the unique id properties are all not null for this bean.

getTargetType

public Class<?> getTargetType()

Return the type of the target.

This is the class of the associated bean, or beans contained in a list, set or map.

getExtraWhere

public String getExtraWhere()

Return an extra clause to add to the query for loading or joining to this bean type.

isOuterJoin

public boolean isOuterJoin()

Return if this association should use an Outer join.

isUpdateable

public boolean isUpdateable()

Return true if this association is updateable.

isInsertable

public boolean isInsertable()

Return true if this association is insertable.

getTableJoin

public TableJoin getTableJoin()

return the join to use for the bean.

getBeanTable

public BeanTable getBeanTable()

Return the BeanTable for this association.

This has the table name which is used to determine the relationship for this association.

getCascadeInfo

public BeanCascadeInfo getCascadeInfo()

Get the persist info.

createImportedId

protected ImportedId createImportedId(BeanPropertyAssoc<?> owner,
                          BeanDescriptor<?> target,
                          TableJoin join)

Build the list of imported property. Matches BeanProperty from the target descriptor back to local database columns in the TableJoin.
