Example 85 with PropertyDescriptor

use of java.beans.PropertyDescriptor in project archi by archimatetool.

the class AbstractTool method applyProperty.

/**
 * This method is invoked from {@link #setProperties(Map)}. Sub-classes can
 * override to add support for more properties. This method should fail
 * silently in case of any error.
 * <p>
 * AbstractTool uses introspection to match any keys with properties. For
 * instance, the key "defaultCursor" would lead to the invocation of
 * {@link #setDefaultCursor(Cursor)} with the provided value.
 *
 * @param key
 *            the key; may be <code>null</code>
 * @param value
 *            the new value
 * @since 3.1
 * @see #setProperties(Map)
