Java CPListElement.getClasspathEntry方法代码示例

/**
 * Shows the UI for configuring a javadoc location attribute of the classpath entry. <code>null</code> is returned
 * if the user cancels the dialog. The dialog does not apply any changes.
 *
 * @param shell The parent shell for the dialog.
 * @param initialEntry The entry to edit. The kind of the classpath entry must be either
 * <code>IClasspathEntry.CPE_LIBRARY</code> or <code>IClasspathEntry.CPE_VARIABLE</code>.
 * @return Returns the resulting classpath entry containing a potentially modified javadoc location attribute
 * The resulting entry can be used to replace the original entry on the classpath.
 * Note that the dialog does not make any changes on the passed entry nor on the classpath that
 * contains it.
 *
 * @since 3.1
