Member Function Documentation

static final boolean compareTo	(	Object	object,
		Object	attribute,
		String	key,
		NSDictionary	params
	)			`[static]`

Compares the specified attribute to a number provided in the params dictionary.

The required key-value pairs include:
"Operator" = The specified operator string. (i.e. "==", "!=", ">", ">=", "<", or "<=" )
"RightOperand" = The number to compare the attribute to. (i.e. 0, 20, etc.)

Parameters:

	object	The object whose attribute is being validated.
	attribute	The attribute being validated.
	key	The key used to access the attribute.
	params	The param dictionary which must contain the above mentioned key-value pairs.

Returns:: true if the comparision succeeds; otherwise, false

static final boolean isInRange	(	Object	object,
		Object	attribute,
		String	key,
		NSDictionary	params
	)			`[static]`

Checks to make sure the attribute falls within the range specified in the params dictionary.
The attribute is allowed to equal the 'Low' or 'High' value.

The required key-value pairs include:
"Low" = The lowest possible value for this attribute.
"High" = The highest possible value for this attribute.

Parameters:

	object	The object whose attribute is being validated.
	attribute	The attribute being validated.
	key	The key used to access the attribute.
	params	The param dictionary which must contain the above mentioned key-value pairs.

Returns:: true if the provided number false within the specified range; otherwise, false

static final boolean isNegativeNumber	(	Object	object,
		Object	attribute,
		String	key,
		NSDictionary	params
	)			`[static]`

Verifies that attribute is a negative number.

Parameters:

	object	The object whose attribute is being validated.
	attribute	The attribute being validated.
	key	The key used to access the attribute.
	params	The param dictionary which must contain the above mentioned key-value pairs.

Returns:: true if the provided number is a negative value; otherwise, false

static final boolean isPositiveNumber	(	Object	object,
		Object	attribute,
		String	key,
		NSDictionary	params
	)			`[static]`

Verifies that attribute is a positive number.

Parameters:

	object	The object whose attribute is being validated.
	attribute	The attribute being validated.
	key	The key used to access the attribute.
	params	The param dictionary which must contain the above mentioned key-value pairs.

Returns:: true if the provided number is positive value; otherwise, false
