NAME

ProgressMonitor::Stringify::Fields::AbstractDynamicField - A reusable/abstract dynamic field implementation for stringify progress.

DESCRIPTION

Inherits from ProgressMonitor::Stringify::Fields::AbstractField. See that for more information; this class signals participation in the dynamic width negotiation protocol as utilized by ProgressMonitor::Stringify::AbstractMonitor and subclasses.

Inherit from this class if you wish to dynamically adjust your field width to grab as much as possible.

METHODS

grabExtraWidth( $extraWidth )

Called with extra width available. Consume all or part of this by updating the inherited width attribute and return the width not used.

This method may be called multiple times in order to fairly distribute extra width across several dynamic fields

isDynamic

Returns true as long as the current width is less than maxWidth.

widthChange

Notification that the width has changed, thus giving the field a chance to recompute some of its attributes as needed.

PROTECTED METHODS

_new( $hashRef, $package )

The constructor, needs to be called by subclasses.

Configuration data:

minWidth (default => 0)

The minimum width this field should use.

maxWidth

The maximum width this field should use.

_set_width( $newWidth )

Calls SUPER and then widthChange.
