Bug 186926 Enhance methods name in IFont, a simple APi class in model
Two issues in IFont interface: 1. Bold is misspelled in setIsBold() method. 2. Setter method name for Boolean arguments is not good. I prefer setBold to setIsBold. There are four boolean-setter methods needing modification like that.
chart/org.eclipse.birt.chart.reportitem/src/org/eclipse/birt/chart/script/api/data/IDateTimeDataElement.java
void setValue( long value );
	/**
	 * Unsets the value of the '{@link org.eclipse.birt.chart.model.data.DateTimeDataElement#getValue <em>Value</em>}'
	 * attribute. <!-- begin-user-doc --> <!-- end-user-doc -->
	 * 
	 * @see #isSetValue()
	 * @see #getValue()
	 * @see #setValue(long)
	 */
	void unsetValue( );
	/**
	 * Returns whether the value of the '
	 * {@link org.eclipse.birt.chart.model.data.DateTimeDataElement#getValue <em>Value</em>}'
	 * attribute is set. <!-- begin-user-doc --> <!-- end-user-doc -->
	 * 
	 * @return whether the value of the '<em>Value</em>' attribute is set.
	 * @see #unsetValue()
	 * @see #getValue()

	boolean isSetValue( );
	/**
	 * A convenient method provided to return the datetime value as a Calendar
	 * 
	 * 
	 * @return calendar date
	 */
	Calendar getValueAsCalendar( );
