class SortedProperties
extends Properties

Specialization of Properties that sorts properties alphanumerically based on their keys.

This can be useful when storing the Properties instance in a properties file, since it allows such files to be generated in a repeatable manner with consistent ordering of properties.

Comments in generated properties files can also be optionally omitted.

SortedProperties

SortedProperties(boolean omitComments)

Construct a new SortedProperties instance that honors the supplied omitComments flag.

参数:

omitComments - true if comments should be omitted when storing properties in a file

SortedProperties

SortedProperties(Properties properties,
 boolean omitComments)

Construct a new SortedProperties instance with properties populated from the supplied Properties object and honoring the supplied omitComments flag.

Default properties from the supplied Properties object will not be copied.

参数:

properties - the Properties object from which to copy the initial properties

omitComments - true if comments should be omitted when storing properties in a file

           throws IOException

覆盖:

store 在类中 Properties

抛出:

IOException

storeToXML

public void storeToXML(OutputStream out,
 String comments)
                throws IOException

覆盖:

storeToXML 在类中 Properties

 String comments,
 String encoding)
                throws IOException

覆盖:

storeToXML 在类中 Properties

抛出:

IOException

keys

public Enumeration<Object> keys()

Return a sorted enumeration of the keys in this Properties object.

覆盖:

keys 在类中 Properties

另请参阅:

• keySet()

keySet

public Set<Object> keySet()

Return a sorted set of the keys in this Properties object.

The keys will be converted to strings if necessary using String.valueOf(Object) and sorted alphanumerically according to the natural order of strings.

指定者:

keySet 在接口中 Map<Object,Object>

覆盖:

keySet 在类中 Properties

entrySet

public Set<Map.Entry<Object,Object>> entrySet()

Return a sorted set of the entries in this Properties object.

The entries will be sorted based on their keys, and the keys will be converted to strings if necessary using String.valueOf(Object) and compared alphanumerically according to the natural order of strings.

指定者:

entrySet 在接口中 Map<Object,Object>

覆盖:

entrySet 在类中 Properties
