PieSectionEntity

public PieSectionEntity(java.awt.Shape area,
                        PieDataset dataset,
                        int pieIndex,

                        java.lang.String urlText)

Creates a new pie section entity.

Parameters:

area - the area.

dataset - the pie dataset.

pieIndex - the pie index (zero-based).

sectionIndex - the section index (zero-based).

sectionKey - the section key.

toolTipText - the tool tip text.

urlText - the URL text for HTML image maps.

Method Detail

getDataset

public PieDataset getDataset()

Returns the dataset this entity refers to.

Returns:

The dataset.

See Also:

setDataset(PieDataset)

setDataset

public void setDataset(PieDataset dataset)

Sets the dataset this entity refers to.

Parameters:

dataset - the dataset.

See Also:

getDataset()

getPieIndex

public int getPieIndex()

Returns the pie index. For a regular pie chart, the section index is 0. For a pie chart containing multiple pie plots, the pie index is the row or column index from which the pie data is extracted.

Returns:

The pie index.

See Also:

setPieIndex(int)

setPieIndex

public void setPieIndex(int index)

Sets the pie index.

Parameters:

index - the new index value.

See Also:

getPieIndex()

getSectionIndex

public int getSectionIndex()

Returns the section index.

Returns:

The section index.

See Also:

setSectionIndex(int)

setSectionIndex

public void setSectionIndex(int index)

Sets the section index.

Parameters:

index - the section index.

See Also:

getSectionIndex()

getSectionKey

public java.lang.Comparable getSectionKey()

Returns the section key.

Returns:

The section key.

See Also:

setSectionKey(Comparable)

setSectionKey

public void setSectionKey(java.lang.Comparable key)

Sets the section key.

Parameters:

key - the section key.

See Also:

getSectionKey()

equals

Tests this entity for equality with an arbitrary object.

Overrides:

equals in class ChartEntity

Parameters:

obj - the object (null permitted).

Overrides:

canEqual in class ChartEntity

Parameters:

other - Object

Returns:

true ONLY if the parameter is THIS class type

hashCode

public int hashCode()

Description copied from class: ChartEntity

Returns a hash code for this instance.

Overrides:
