org.elkoserver.json.JSONLiteralArray

public class JSONLiteralArray
extends Object

A literal JSON string, representing an array, undergoing incremental construction. Users of this class should call the constructor to begin creation of the literal, incrementally add to it using the various addElement() methods, then finally complete it by calling the finish() method. After the literal is completed, it may be used as another literal's parameter value.

value - The (Encodable) element value.

addElement

public void addElement(double value)

Add a floating point element to an incomplete array.

Parameters:

value - The (double) element value.

addElement

public void addElement(boolean value)

Add a boolean element to an incomplete array.

Parameters:

value - The (boolean) element value.

addElement

public void addElement(int value)

Add an integer element to an incomplete array.

Parameters:

value - The (int) element value.

addElement

public void addElement(long value)

Add a long element to an incomplete array.

Parameters:

value - The (long) element value.

addElement

public void addElement(JSONObject value)

Add a JSON object element to an incomplete array.

Parameters:

value - The (JSONObject) element value.

addElement

public void addElement(Referenceable value)

Add a reference element to an incomplete array.

Parameters:

value - The (Referenceable) element value.

addElement

public void addElement(String value)

Add a string element to an incomplete array.

Parameters:

value - The (String) element value.

finish

public void finish()

Finish construction of the literal.

Throws:

Error - if you try to finish a literal that is already complete.

sendableString

public String sendableString()

Obtain a string representation of this literal suitable for output to a connection.

Returns:

a sendable string representation of this literal.

Throws:

Error - if the literal is not finished.

size

public int size()

Obtain the array's element count.

Returns:

the number of elements in this array (so far).

toString
