A \fIproperty\fP \fIlist\fP (or \fIplist\fP for short) is a list of zero or more properties. A property consists of a \fIkey\fP and a \fIvalue\fP, where key is a symbol and value is anything that can be cast to \fC(void *)\fP. .PP If the key of a property is a \fImanaging\fP \fIkey\fP, its \fIvalue\fP is a \fImanaged\fP \fIobject\fP. A property list itself is a managed objects. .PP If each key of a plist is one of \fBMsymbol\fP, \fBMtext\fP, \fBMinteger\fP, and \fBMplist\fP, the plist is called as \fIwell\-formed\fP and represented by the following notation in the documentation. .PP .PP .nf PLIST ::= '(' ELEMENT * ')' ELEMENT ::= INTEGER | SYMBOL | M\-TEXT | PLIST M\-TEXT ::= '"' text data ... '"' .fi .PP .PP For instance, if a plist has four elements; integer \-20, symbol of name 'sym', M\-text of contents 'abc', and plist of integer 10 and symbol of name 'another\-symbol', it is represented as this: .PP (\-20 sym 'abc' (10 another\-symbol)) .SH "Typedef Documentation" .PP .SS "typedef struct \fBMPlist\fP \fBMPlist\fP" .PP Type of property list objects. The type \fBMPlist\fP is for a \fIproperty\fP \fIlist\fP object. Its internal structure is concealed from application programs. .SH "Variable Documentation" .PP .SS "\fBMSymbol\fP \fBMinteger\fP" .PP Symbol whose name is 'integer'. The symbol \fCMinteger\fP has the name \fC'integer'\fP. The value of a property whose key is \fCMinteger\fP must be an integer. .SS "\fBMSymbol\fP \fBMplist\fP" .PP Symbol whose name is 'plist'. The symbol \fCMplist\fP has the name \fC'plist'\fP. It is a managing key. A value of a property whose key is \fCMplist\fP must be a plist. .SS "\fBMSymbol\fP \fBMtext\fP" .PP Symbol whose name is 'mtext'. The symbol \fCMtext\fP has the name \fC'mtext'\fP. It is a managing key. A value of a property whose key is \fCMtext\fP must be an M\-text. .SH "Author" .PP Generated automatically by Doxygen for The m17n Library from the source code. .SH COPYRIGHT Copyright (C) 2001 Information\-technology Promotion Agency (IPA) .br Copyright (C) 2001\-2011 National Institute of Advanced Industrial Science and Technology (AIST) .br Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License .
