this(InputStream stream) ¶

Propagate ctor to superclass.

int opApply(scope int delegate(ref const(T)[] name, ref const(T)[] value) dg) [final] ¶

Load properties from the provided stream, via a foreach.

We use an iterator to sweep text lines, and extract lValue and rValue pairs from each one, The expected file format is as follows:

x = y
abc = 123
x.y.z = this is a single property

# this is a comment line

Note that the provided name and value are actually slices and should be copied if you intend to retain them (using name.dup and value.dup where appropriate.)

Load the input stream into an AA.

class MapOutput(T) : OutputFilter ¶

Provides write facilities on a properties stream. That is, a file or other medium which will contain lines of text with a name=value layout.

this(OutputStream stream, const(T)[] newline = NL) ¶

Append a comment to the provided stream.
