Constructor Detail

DoubleValidator

public DoubleValidator()

Method Detail

getMaximum

public double getMaximum()

Return the configured maximum value for this validator.

setMaximum

public void setMaximum(double maximum)

Set the configured maximum value for this validator.

Parameters:

maximum - The new maximum value

getMinimum

public double getMinimum()

Return the configured minimum value for this validator.

setMinimum

public void setMinimum(double minimum)

Set the configured minimum value for this validator.

Parameters:

minimum - The new minimum value

validate

public void validate(javax.faces.context.FacesContext context,
                     javax.faces.component.UIComponent component,
                     Object value)
              throws javax.faces.validator.ValidatorException

Perform the correctness checks implemented by this Validator against the specified UIComponent. If any violations are found, a ValidatorException will be thrown containing the FacesMessage describing the failure.

IMPLEMENTATION NOTE: Unlike earlier implementations of Shale Validator integration, validators that subclass this class do not support the option to skip server side validation.

Specified by:

validate in interface javax.faces.validator.Validator

Specified by:

validate in class AbstractValidator

Parameters:

context - FacesContext for the current request

component - UIComponent we are checking for correctness

value - The value to validate

Throws:

javax.faces.validator.ValidatorException - if validation fails

restoreState

public void restoreState(javax.faces.context.FacesContext context,
                         Object state)

Specified by:

restoreState in interface javax.faces.component.StateHolder

Overrides:

restoreState in class AbstractValidator

saveState

public Object saveState(javax.faces.context.FacesContext context)

Specified by:

saveState in interface javax.faces.component.StateHolder

Overrides:

saveState in class AbstractValidator
