NAME

ProgressMonitor::Stringify::AbstractMonitor - A reusable/abstract monitor implementation that deals in stringified feedback.

DESCRIPTION

This is an abstract base class for monitors that will render their result as a string through the use of 'fields' (see the Fields packages).

PROTECTED METHODS

_new( $hashRef, $package )

Configuration data:

maxWidth (default => 79)

The monitor should have this maxWidth. The actual width used may be less. This depends on the fields it uses; specifically, if dynamic fields are used, they will be given width until all is used or until the dynamic fields themselves have reached their maxWidth if any.

Throws X::ProgressMonitor::InsufficientWidth if the maxWidth is to small to handle the minimum requirements for all the fields.

fields (default => [])

An array ref with field instances.

messageStrategy (default => newline)

An identifiers that describes how messages should be inserted into the rendition:

none

Not surprisingly, this suppresses message presentation.

overlay

This will cause the message to overlay one or more of the other fields, so as to keep things on one line. This setting will work in conjunction with messageTimeout, messageOverlayStartField and messageOverlayEndField.

newline

This will cause the message and a newline to be inserted in front of the regular rendition, causing the running rendition to be 'pushed' forward.

overlay_newline

This will combine the effects of 'overlay' and 'newline'.

messageFiller (default => ' ')

If the message is too short for the allotted space, it will be filled with this character. Can be set to the empty string or undef to skip filling, causing a 'partial overlay', i.e. just as much as the string is, which obviously can give a confusing mixed message with the underlying field.

messageTimeout (default => 3 seconds)

This is only relevant for the 'overlay' strategy. If the code doesn't explicitly set the message to undef/blank, the timeout will automatically remove it. Set to -1 for infinite.

messageOverlayStartField, messageOverlayEndField (defaults => all fields)

Together these define the starting and ending field number that the message should overlay. This defaults to 'all fields'.

_toString

Contains the logic to assemble the fields into a current string.
