Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

public java.lang.String getParentColumn()

setParentColumn

public void setParentColumn(java.lang.String newval)

getChildColumn

public java.lang.String getChildColumn()

setChildColumn

public void setChildColumn(java.lang.String newval)

getTable

setTable

public void setTable(MondrianModel.Table newval)

getChildren

public java.util.List<OLAPObject> getChildren()

Description copied from class: OLAPObject

Returns a read-only unified list of all children of this OLAPObject. If this object doesn't have any children, returns an empty list.

Specified by:

getChildren in class OLAPObject

allowsChildren

public boolean allowsChildren()

Description copied from class: OLAPObject

Returns true if this type of OLAPObject can ever return a non-empty list from OLAPObject.getChildren(), and false if getChildren() is always empty.

Specified by:

allowsChildren in class OLAPObject

addChild

public void addChild(OLAPObject child)

Description copied from class: OLAPObject

Adds the given child or sets the appropriate property on this OLAPObject, if this type of OLAPObject has the applicable addXXX() or setXXX() method for the given object's type.

This method in the abstract base class always throws the IllegalArgumentException because no children or properties are defined at this level.

This method isn't compile-time type safe, so it is recommended not to use it on "by-hand" usage of this API. This method is used during XML parsing, which can't be made compile-time type safe anyway.

Overrides:

addChild in class OLAPObject

Parameters:

child - The child to add.

addChild

public void addChild(int index,
                     OLAPObject child)

Description copied from class: OLAPObject

Adds the given child or sets the appropriate property on this OLAPObject, allowing the overall target index to be specified.

This method in the abstract base class always throws IllegalArgumentException because no children or properties are defined at this level.

This method isn't compile-time type safe, so it is recommended not to use it on "by-hand" usage of this API. This method is used for undo and redo, which can't be compile-time type safe anyway.

Overrides:

addChild in class OLAPObject

Parameters:

index - The overall index (same index as would be in OLAPObject.getChildren()) at which to add the child.

child - The child to add.

removeChild

public boolean removeChild(OLAPObject child)

Description copied from class: OLAPObject

Removes the given child on this OLAPObject if this type of OLAPObject has the applicable removeXXX() or setXXX(null) method for the given object's type.

This method in the abstract base class always throws the IllegalArgumentException because no children or properties are defined at this level.

Overrides:

removeChild in class OLAPObject

Parameters:

child - The child to remove.
