NAME

Brannigan::Validations - Built-in validation methods for Brannigan.

VERSION

version 0.8

DESCRIPTION

This module contains all built-in validation methods provided natively by the Brannigan input validation/parsing system.

METHODS

All these methods receive the value of a parameter, and other values that explicilty define the requirements. They return a true value if the parameter's value passed the test, or a false value otherwise.

required( $value, $boolean )

If $boolean has a true value, this method will check that a required parameter was indeed provided; otherwise (i.e. if $boolean is not true) this method will simply return a true value to indicate success.

You should note that if a parameter is required, and a non-true value is received (i.e. 0 or the empty string ""), this method considers the requirement as fulfilled (i.e. it will return true). If you need to make sure your parameters receive true values, take a look at the is_true() validation method.

Please note that if a parameter is not required and indeed isn't provided with the input parameters, any other validation methods defined on the parameter will not be checked.

forbidden( $value, $boolean )

If $boolean has a true value, this method will check that a forbidden parameter was indeed NOT provided; otherwise (i.e. if $boolean has a false value), this method will do nothing and simply return true.

is_true( $value, $boolean )

If $boolean has a true value, this method will check that $value has a true value (so, $value cannot be 0 or the empty string); otherwise (i.e. if $boolean has a false value), this method does nothing and simply returns true.

length_between( $value, $min_length, $max_length )

Makes sure the value's length (stringwise) is inside the range of $min_length-$max_length, or, if the value is an array reference, makes sure it has between $min_length and $max_length items.

min_length( $value, $min_length )

Makes sure the value's length (stringwise) is at least $min_length, or, if the value is an array reference, makes sure it has at least $min_length items.

max_length( $value, $max_length )

Makes sure the value's length (stringwise) is no more than $max_length, or, if the value is an array reference, makes sure it has no more than $max_length items.

exact_length( $value, $length )

Makes sure the value's length (stringwise) is exactly $length, or, if the value is an array reference, makes sure it has exactly $exact_length items.

integer( $value, $boolean )

If boolean is true, makes sure the value is an integer.

value_between( $value, $min_value, $max_value )

Makes sure the value is between $min_value and $max_value.

min_value( $value, $min_value )

Makes sure the value is at least $min_value.

max_value( $value, $max )

Makes sure the value is no more than $max_value.

array( $value, $boolean )

If $boolean is true, makes sure the value is actually an array reference.

hash( $value, $boolean )

If $boolean is true, makes sure the value is actually a hash reference.

one_of( $value, @values )

Makes sure a parameter's value is one of the provided acceptable values.
