Method Details

setRenderingIndex

default void setRenderingIndex(int index)

Set the rendering index of this part. Rendering index is the position of this part on the chart when it is being rendered. It is up to the part to keep this value if required.

Parameters:

index - Rendering index.

getRenderingIndex

default int getRenderingIndex()

Return the rendering index of this part. The default implementation returns -1.

Returns:

Rendering index.

getId

long getId()

Each part should have a unique Id. (It can be a final variable and can be set by calling ID.newID().

Returns:

Unique Id.

setSerial

void setSerial(int serial)

Set a serial number (Serial number used internal purposes only). The implementation of this method must be in such a way that the serial number set here must be returned by the getSerial() method.

Parameters:

serial - Serial number to set.

getSerial

int getSerial()

Get the current serial number (Serial number used internal purposes only). The serial number set by the setSerial(int) method should be returned by this method.

Returns:

Current serial number.

encode

static void encode(StringBuilder sb,
 String name,
 Object value)

Helper method: Encode a (name, value) pair.

Parameters:

sb - Encoded JSON string to be appended to this.

name - Name to be encoded.

value - Value to be encoded.

addComma

static void addComma(StringBuilder sb)

Helper method: Add a comma if required.

Parameters:

sb - Add a comma to this.

encodeFunction

static void encodeFunction(StringBuilder sb,
 String name,
 String body,
 String... params)

Helper method: Encode a generic function

Parameters:

sb - Encoded JSON string to be appended to this.

name - Name to be encoded (if null, name-part will not be encoded)

body - Body of the function.

params - Parameters of the function.

encodeFunction

static String encodeFunction(String body,
 String... params)

Helper method: Encode a generic function as a string.

Parameters:

body - Body of the function.

params - Parameters.

Returns:

Encoded value.

removeComma

static void removeComma(StringBuilder sb)

Helper method: Replace trailing commas with spaces.

Parameters:

sb - Replace trailing commas in this.

validate

void validate()
       throws ChartException

This method is invoked by SOChart to check if the component or part is valid or not.

Throws:

ChartException - Raises exception if the component or part is not valid.

className

default String className()

Helper method to return the class name of the component/part in a more human-friendly way.

Returns:

Name of the class that can be used for showing a message to the end users.

getName

Get the name of this part.

Returns:

Name

setName

default void setName(String name)
