Method Detail

getBottom

public double getBottom()

Returns the bottom of the valid double range.

setBottom

public void setBottom(double bottom)

Sets the bottom of the valid double range.

The default value is the minimum double value.

getTop

public double getTop()

Returns the top of the valid double range.

setTop

public void setTop(double top)

Sets the top of the valid double range.

The default value is the maximum double value.

setRange

public void setRange(double bottom,
                     double top)

Sets the range of valid doubles.

validate

public WValidator.Result validate(java.lang.String input)

Validates the given input.

The input is considered valid only when it is blank for a non-mandatory field, or represents a double within the valid range.

Overrides:

setInvalidNotANumberText

public void setInvalidNotANumberText(java.lang.CharSequence text)

Sets the message to display when the input is not a number.

The default value is "Must be a number."

getInvalidNotANumberText

public WString getInvalidNotANumberText()

Returns the message displayed when the input is not a number.

See Also:

setInvalidNotANumberText(CharSequence text)

setInvalidTooSmallText

public void setInvalidTooSmallText(java.lang.CharSequence text)

Sets the message to display when the number is too small.

Depending on whether getBottom() and getTop() are real bounds, the default message is "The number must be between {1} and {2}" or "The number must be larger than {1}".

getInvalidTooSmallText

public WString getInvalidTooSmallText()

Returns the message displayed when the number is too small.

See Also:

setInvalidTooSmallText(CharSequence text)

setInvalidTooLargeText

public void setInvalidTooLargeText(java.lang.CharSequence text)

Sets the message to display when the number is too large.

Depending on whether getBottom() and getTop() are real bounds, the default message is "The number must be between {1} and {2}" or "The number must be smaller than {2}".

getInvalidTooLargeText

public WString getInvalidTooLargeText()

Returns the message displayed when the number is too large.

See Also:

setInvalidTooLargeText(CharSequence text)

getJavaScriptValidate

public java.lang.String getJavaScriptValidate()

Description copied from class: WValidator

Creates a Javascript object that validates the input.

The JavaScript expression should evaluate to an object which contains a validate(text) function, which returns an object that contains the following two fields:

• fields: a boolean valid,
• a message that indicates the problem if not valid.

Returns an empty string if the validator does not provide a client-side validation implementationq.

Note: The signature and contract changed changed in JWt 3.1.9.

Overrides:
