Constructor Detail

InheritInfo

public InheritInfo(InheritInfo r,
                   InheritInfo parent,
                   DeployInheritInfo deploy)

Method Detail

visitChildren

public void visitChildren(InheritInfoVisitor visitor)

Visit all the children in the inheritance tree.

appendCheckConstraintValues

public void appendCheckConstraintValues(String propertyName,
                                        Set<String> checkConstraintValues)

Append check constraint values for the entire inheritance hierarchy.

setDescriptor

public void setDescriptor(BeanDescriptor<?> descriptor)

Set the descriptor for this node.

desc

public BeanDescriptor<?> desc()

Return the associated BeanDescriptor for this node.

localProperties

public BeanProperty[] localProperties()

Return the local properties for this node in the hierarchy.

getChildren

public List<InheritInfo> getChildren()

Return the children.

hasChildren

public boolean hasChildren()

Return true if this node has children.

When an inheritance node has no children then we don't need the discriminator column as the type is effectively known.

addChildrenProperties

public void addChildrenProperties(SqlTreeProperties selectProps)

Add the local properties for each sub class below this one.

readType

public InheritInfo readType(DbReadContext ctx)
                     throws SQLException

Return the associated InheritInfo for this DB row read.

Throws:

SQLException

readType

public InheritInfo readType(Class<?> beanType)

Return the associated InheritInfo for this bean type.

createEntityBean

public EntityBean createEntityBean()

Create an EntityBean for this type.

getIdBinder

public IdBinder getIdBinder()

Return the IdBinder for this type.

getType

public Class<?> getType()

return the type.

getRoot

public InheritInfo getRoot()

Return the root node of the tree.

The root has a map of discriminator values to types.

getParent

public InheritInfo getParent()

Return the parent node.

isRoot

public boolean isRoot()

Return true if this is the root node.

isConcrete

public boolean isConcrete()

Return true if this is considered a concrete type in the inheritance hierarchy.

getType

public InheritInfo getType(String discValue)

For a discriminator get the inheritance information for this tree.

addChild

public void addChild(InheritInfo childInfo)

Add a child node.

getWhere

public String getWhere()

Return the derived where for the discriminator.

getDiscriminatorColumn

public String getDiscriminatorColumn()

Return the column name of the discriminator.

getDiscriminatorType

public int getDiscriminatorType()

Return the sql type of the discriminator value.

getColumnLength

public int getColumnLength()

Return the length of the discriminator column.

getColumnDefn

public String getColumnDefn()

Return the explicit column definition.

getDiscriminatorValue

public Object getDiscriminatorValue()

toString

public String toString()

Overrides:

toString in class Object
