Constructor Detail

AbstractAxisLabel

public AbstractAxisLabel(MemberInterface member,
                         int minCoord,
                         int maxCoord)

Constructor.

Parameters:

member - The member associated with this label.

minCoord - The smallest axis coordinate spanned by the label. Must be greater than or equal to zero, and less than or equal to maxCoord.

maxCoord - The largest axis coordinate spanned by the label. Must be greater than or equal to zero, and greater than or equal to minCoord.

getMember(), getMinimumCoordinate(), getMaximumCoordinate()

Method Detail

getAxis

public final AxisInterface getAxis()

Returns the axis that this label is associated with. (Convenience method for getMember().getLevel().getDimension().getAxis().)

Specified by:

getAxis in interface AxisLabelInterface

Returns:

The label's axis.

See Also:

AxisInterface

getLabel

public String getLabel()
                throws TableException

Returns the label's label, i.e. its descriptive text.

Specified by:

getLabel in interface NodeInterface

Returns:

getMember().getLabel()

Throws:

TableException - Thrown if the query can not be satisfied (e.g. i/o-failure).

getMember

public final MemberInterface getMember()

Returns the member that this label is associated with.

Specified by:

getMember in interface AxisLabelInterface

Returns:

The label's member.

See Also:

MemberInterface

getMinimumCoordinate

public int getMinimumCoordinate()

Returns the smallest axis coordinate spanned by the label. If this is a leaf label, getMinimumCoordinate() will equal getMaximumCoordinate().

Specified by:

getMinimumCoordinate in interface AxisLabelInterface

Returns:

A zero-based integer that identifies a point along the axis.

See Also:

getMaximumCoordinate()

getMaximumCoordinate

public int getMaximumCoordinate()

Returns the largest axis coordinate spanned by the label. If this is a leaf label, getMinimumCoordinate() will equal getMaximumCoordinate().

Specified by:

getMaximumCoordinate in interface AxisLabelInterface

Returns:

A zero-based integer that identifies a point along the axis.

See Also:

getMinimumCoordinate()

getName

public String getName()
               throws TableException

Returns the label's name. The name is the label's unique identifier; whether the identifier is unique throughout the tree or just within the domain of the label's parent is implementation specific.

Specified by:

getName in interface NodeInterface

Returns:

getMember().getName()

Throws:

TableException - Thrown if the query can not be satisfied (e.g. i/o-failure).

getNodeChildren

public SimpleNodeInterface[] getNodeChildren(int index,
                                             int count)

Returns the child labels associated with a given range of indices. The default implementation simply calls getNodeChild count-times; subclass should override if it can do so more efficiently.

Specified by:

getNodeChildren in interface SimpleNodeInterface

Parameters:

index - A zero-based child index (0 to getNodeChildCount()-1).

count - The number of child labels to return.

Returns:

An array whose first element is the child label associated with index, whose second element is the child label associated with index+1, and so on such that array[array.length-1] is the child label associated with index+count-1.

Throws:

IndexOutOfBoundsException - Thrown if index is negative, or greater than or equal to getNodeChildCount().

getNodeType

public String getNodeType()

Returns the label's type. The type serves to categorize a node, i.e. identify it as belonging to a particular group.

Specified by:

getNodeType in interface NodeInterface

Returns:

"label".
