Class Props

java.lang.Object
  jodd.props.Props

All Implemented Interfaces:

java.lang.Cloneable

public class Props
extends java.lang.Object
implements java.lang.Cloneable

Super properties: fast, configurable, supports (ini) sections, profiles.

Basic parsing rules:

By default, props files are UTF8 encoded.

Leading and trailing spaces will be trimmed from section names and property names.

Leading and/or trailing spaces may be trimmed from property values.

You can use either equal sign (=) or colon (:) to assign property values

Comments begin with either a semicolon (;), or a sharp sign (#) and extend to the end of line. It doesn't have to be the first character.

A backslash (\) escapes the next character (e.g., \# is a literal #, \\ is a literal \).

If the last character of a line is backslash (\), the value is continued on the next line with new line character included.

\\uXXXX is encoded as character

\t, \r and \f are encoded as characters

Sections rules:

Section names are enclosed between [ and ].

Properties following a section header belong to that section. Section name is added as a prefix to section properties.

Section ends with empty section definition [] or with new section start

Profiles rules:

Profile names are enclosed between < and > in property key.

Each property key may contain zero, one or more profile definitions.

Macro rules:

Profile values may contain references to other properties using ${ and }

Inner references are supported

References are resolved first in the profile context and then in the base props context.

load

public void load(java.lang.String data)

Loads props from the string.

load

public void load(java.io.File file)
          throws java.io.IOException

Loads props from the file. Assumes UTF8 encoding unless the file ends with '.properties', than it uses ISO 8859-1.

Throws:
