NAME

Data::TreeValidator::Branch - A branch of tree validation

DESCRIPTION

Represents a branch in the tree, ie something that has child nodes. Almost all your validation specifications will have at least one tree (unless it really only takes a single piece of input).

METHODS

children

Returns a list of all child nodes of this branch

child_names

Returns the names of all child nodes for this branch

add_child($name => $value)

Adds a child to the branch, with the name $name and value $value

child($name)

Returns the child with name $name, or undef

process($input)

Takes the input in $input and validates it against this branch. The general process here is to enumerate over each child of this branch, and fetch the corresponding data from $input and process that.

Returns a Data::TreeValidator:::Result::Branch, which can be inspected to determine if the branch validated, and for clean data.
