protected  float[] suggestions
          Current value set for the suggested response values.
 
Constructor Summary
PropertiesQuestion.FloatConstraints()
           
PropertiesQuestion.FloatConstraints(float[] suggestions)
          Construct with suggestions for the user.
PropertiesQuestion.FloatConstraints(float min, float max)
           
PropertiesQuestion.FloatConstraints(float min, float max, float[] suggestions)
          Construct with both min, max and suggested values.
 
Method Summary
 float getLowerBound()
          Get the lower bound which specifies the minimum possible value to be considered a valid response from the user.
 float getResolution()
          Get the resolution for responses to this question.
 float[] getSuggestions()
          Get the suggested values.
 float getUpperBound()
          Get the upper bound which specifies the maximum possible value to be considered a valid response from the user.
 boolean isCustomValuesAllowed()
          Are custom user values allowed?
 java.lang.String isValid(float v)
          Is the given value valid for this field?
 java.lang.String isValid(java.lang.String v)
          Is the given value valid for this field? The basic check for validity is to see if the given string can be parsed as an floating point value in the current locale.
 void setBounds(float min, float max)
          Set the max/min possible value that should be considered valid.
 void setCustomValuesAllowed(boolean state)
          Are user specified values allowed? If not, there must be suggestions present.
 void setResolution(float resolution)
          Set the resolution for responses to this question.
 void setSuggestions(float[] sugs)
          Supply some possible values that the user may want to select from.

Method Detail

setBounds

public void setBounds(float min,
                      float max)
Set the max/min possible value that should be considered valid. The range in inclusive. The defaults are the MIN and MAX values for the float datatype.

Parameters:
min - Minimum valid response value.
max - Maximum valid response value.

getLowerBound

public float getLowerBound()
Get the lower bound which specifies the minimum possible value to be considered a valid response from the user.

Returns:
Minimum boundary (inclusive).

getUpperBound

public float getUpperBound()
Get the upper bound which specifies the maximum possible value to be considered a valid response from the user.

Returns:
Maximum boundary (inclusive).

getSuggestions

public float[] getSuggestions()
Get the suggested values. Not a copy, do not alter the array.

Returns:
Suggested response values currently set for this question. Null if none have been set.
See Also:
setSuggestions(float[])

setCustomValuesAllowed

public void setCustomValuesAllowed(boolean state)
Are user specified values allowed? If not, there must be suggestions present.

Throws:
java.lang.IllegalStateException - If no suggestions have been provided.
See Also:
setSuggestions(float[])

isCustomValuesAllowed

public boolean isCustomValuesAllowed()
Are custom user values allowed?

See Also:
setCustomValuesAllowed(boolean), setSuggestions(float[])

setSuggestions

public void setSuggestions(float[] sugs)
Supply some possible values that the user may want to select from.

Parameters:
sugs - Suggested values to present the user for this question. Should be an array of length greater than zero.
See Also:
getSuggestions()

setResolution

public void setResolution(float resolution)
Set the resolution for responses to this question. Responses may be rounded to the nearest multiple of the resolution.

Parameters:
resolution - the resolution for responses to this question
See Also:
getResolution(), PropertiesQuestion.setValue(java.lang.String)

getResolution

public float getResolution()
Get the resolution for responses to this question. Responses may be rounded to the nearest multiple of the resolution.

Returns:
the resolution for responses to this question
See Also:
setResolution(float), PropertiesQuestion.setValue(java.lang.String)

isValid

public java.lang.String isValid(java.lang.String v)
Is the given value valid for this field? The basic check for validity is to see if the given string can be parsed as an floating point value in the current locale.

Overrides:
isValid in class PropertiesQuestion.ValueConstraints
Parameters:
v - The value to check.
Returns:
Null if the valid is valid, a localized reason string otherwise.
See Also:
PropertiesQuestion.getInvalidKeys()

isValid

public java.lang.String isValid(float v)
Is the given value valid for this field?

Returns:
Null if the valid is valid, a localized reason string otherwise.
