Method Detail

getAnnotationMap

public Map<String,Annotation> getAnnotationMap()

Description copied from interface: Annotated

Returns a list of annotations.

The map may be empty, never null.

Specified by:

getAnnotationMap in interface Annotated

Returns:

Map from annotation name to annotations.

getNameUniqueWithinQuery

public String getNameUniqueWithinQuery()

Description copied from interface: NamedSet

Returns a name for this set that is unique within the query.

This is necessary when there are several 'AS' expressions, or an 'AS' expression overrides a named set defined using 'WITH MEMBER' clause or against a cube.

Specified by:

getNameUniqueWithinQuery in interface NamedSet

isDynamic

public boolean isDynamic()

Description copied from interface: NamedSet

Returns whether this named set is dynamic.

Evaluation rules:

• A dynamic set is evaluated each time it is used, and inherits the context in which it is evaluated.
• A static set is evaluated only on first use, in the base context of the cube.

Specified by:

isDynamic in interface NamedSet

Returns:

Whether this named set is dynamic

clone

public Object clone()

Overrides:

clone in class OlapElementBase

getLogger

protected org.apache.log4j.Logger getLogger()

Specified by:

getLogger in class OlapElementBase

getUniqueName

public String getUniqueName()

Specified by:

getUniqueName in interface OlapElement

getName

public String getName()

Specified by:

getName in interface OlapElement

getQualifiedName

public String getQualifiedName()

Description copied from interface: OlapElement

Returns the name of this element qualified by its class, for example "hierarchy 'Customers'".

Specified by:

getQualifiedName in interface OlapElement

getDescription

public String getDescription()

Specified by:

getDescription in interface OlapElement

getHierarchy

public Hierarchy getHierarchy()

Specified by:

getHierarchy in interface OlapElement

getDimension

public Dimension getDimension()

Description copied from interface: OlapElement

Returns the dimension of a this expression, or null if no dimension is defined. Applicable only to set expressions.

Example 1:

 [Sales].children
 

has dimension [Sales].

Example 2:

 order(except([Promotion Media].[Media Type].members,
              {[Promotion Media].[Media Type].[No Media]}),
       [Measures].[Unit Sales], DESC)
 

has dimension [Promotion Media].

Example 3:

 CrossJoin([Product].[Product Department].members,
           [Gender].members)
 

has no dimension (well, actually it is [Product] x [Gender], but we can't represent that, so we return null);

Specified by:

getDimension in interface OlapElement

lookupChild

public OlapElement lookupChild(SchemaReader schemaReader,
                               Id.Segment s,
                               MatchType matchType)

Description copied from interface: OlapElement

Looks up a child element, returning null if it does not exist.

Specified by:

lookupChild in interface OlapElement

setName

public void setName(String name)

Description copied from interface: NamedSet

Sets the name of this named set.

Specified by:

setName in interface NamedSet

setDescription

public void setDescription(String description)

setAnnotationMap

public void setAnnotationMap(Map<String,Annotation> annotationMap)

getExp

public Exp getExp()

Description copied from interface: NamedSet

Returns the expression used to derive this named set.

Specified by:

getExp in interface NamedSet

validate

public NamedSet validate(Validator validator)

Specified by:

validate in interface NamedSet

getType

public Type getType()

Description copied from interface: NamedSet

Returns the type of this named set.

Specified by:

getType in interface NamedSet
