## Class TRangeValidator

Description

TRangeValidator class

TRangeValidator tests whether an input value is within a specified range.

TRangeValidator uses three key properties to perform its validation. The MinValue and MaxValue properties specify the minimum and maximum values of the valid range. The DataType property is used to specify the data type of the value and the minimum and maximum range values. These values are converted to this data type before the validation operation is performed. The following value types are supported:

- Integer A 32-bit signed integer data type.
- Float A double-precision floating point number data type.
- Date A date data type. The date format can be specified by setting DateFormat property, which must be recognizable by TSimpleDateFormatter. If the property is not set, the GNU date syntax is assumed.
- String A string data type.

Methods
evaluateIsValid (line 121)

This method overrides the parent's implementation.

The validation succeeds if the input data is within the range. The validation always succeeds if the input data is empty.

- return: whether the validation succeeds
- access: protected

boolean evaluateIsValid ()

Redefinition of:

TBaseValidator::evaluateIsValid()
  This is the major method for validation.

getClientScriptOptions (line 236)

Returns an array of javascript validator options.

- return: javascript validator options.
- access: protected

array getClientScriptOptions ()

Redefinition of:

TBaseValidator::getClientScriptOptions()
  Returns an array of javascript validator options.

getDataType (line 83)

- return: the data type that the values being compared are converted to before the comparison is made. Defaults to String.
- access: public

string getDataType ()
getDateFormat (line 110)

- return: the date validation date format if any
- access: public

string getDateFormat ()
getMaxValue (line 65)

- return: the maximum value of the validation range.
- access: public

string getMaxValue ()
getMinValue (line 48)

- return: the minimum value of the validation range.
- access: public

string getMinValue ()
isValidDate (line 184)

Determine if the date is within the specified range.

Uses pradoParseDate and strtotime to get the date from string.

- return: true if within range.
- access: protected

boolean isValidDate (string $value)

- string $value: date as string to validate

isValidFloat (line 164)

Determine if the value is within the specified float range.

- return: true if within range.
- access: protected

boolean isValidFloat (string $value)

- string $value: value to validate

isValidInteger (line 145)

Determine if the value is within the integer range.

- return: true if within integer range.
- access: protected

boolean isValidInteger (string $value)

- string $value: value to validate true

isValidString (line 219)

Compare the string with a minimum and a maxiumum value.

Uses strcmp for comparision.

- return: true if the string is within range.
- access: protected

boolean isValidString (string $value)

- string $value: value to compare with.

setDataType (line 93)

Sets the data type (Integer, Float, Date, String) that the values being compared are converted to before the comparison is made.

- access: public

void setDataType (string $value)

- string $value: the data type

setDateFormat (line 102)

Sets the date format for a date validation

- access: public

void setDateFormat (string $value)

- string $value: the date format value

setMaxValue (line 74)

Sets the maximum value of the validation range.

- access: public

void setMaxValue (string $value)

- string $value: the maximum value

setMinValue (line 57)

Sets the minimum value of the validation range.

- access: public

void setMinValue (string $value)

- string $value: the minimum value
