All Implemented Interfaces:
PropertyEditor

Custom java.beans.PropertyEditor for Properties objects.

Handles conversion from content String to Properties object. Also handles Map to Properties conversion, for populating a Properties object via XML "map" entries.

The required format is defined in the standard Properties documentation. Each property must be on a new line.

public void setAsText(String text) throws IllegalArgumentException { Properties props = new Properties(); if (text != null) { try { // Must use the ISO-8859-1 encoding because Properties.load(stream) expects it. props.load(new ByteArrayInputStream(text.getBytes("ISO-8859-1"))); } catch (IOException ex) { // Should never happen. throw new IllegalArgumentException( "Failed to parse [" + text + "] into Properties: " + ex.getMessage()); } } setValue(props); } Convert String into Properties , considering it as properties content.
