public NumberFieldType()

Method Detail

getMetaData

public ElementMetaData getMetaData()

Specified by:

getMetaData in interface ElementType

getDesignValue

public Object getDesignValue(ExpressionRuntime runtime,
                             Element element)

Specified by:

getDesignValue in interface ElementType

getRawValue

public Object getRawValue(ExpressionRuntime runtime,
                          Element element)

Returns the unformated raw value. Whether that raw value is useable for the export is beyond the scope of this API definition, but providing access to Number or Date objects is a good idea.

Specified by:

getRawValue in interface RawDataSource

Parameters:

runtime - the expression runtime that is used to evaluate formulas and expressions when computing the value of this filter.

element -

Returns:

the raw data.

getFormatString

public FormatSpecification getFormatString(ExpressionRuntime runtime,
                                           Element element,
                                           FormatSpecification formatSpecification)

Returns information about the formatstring that was used to transform a raw-value into a formatted text. Not all elements will make use of a format-string. These elements will return FormatSpecification.TYPE_UNDEFINED in that case.

Specified by:

getFormatString in interface RawDataSource

Parameters:

runtime - the Expression runtime used to possibly compute the raw-value.

element - the element to which this datasource is added.

formatSpecification - the format specification (can be null). @return a filled format specififcation. If the formatSpecification parameter was not null, this given instance is reused.

configureDesignTimeDefaults

public void configureDesignTimeDefaults(Element element,
                                        Locale locale)

Specified by:

configureDesignTimeDefaults in interface ElementType

getValue

public Object getValue(ExpressionRuntime runtime,
                       Element element)

Returns the current value for the data source.

Specified by:

getValue in interface DataSource

Parameters:

runtime - the expression runtime that is used to evaluate formulas and expressions when computing the value of this filter.

element - the element from which to read attribute.

Returns:

the value.

clone

public Object clone()
             throws CloneNotSupportedException

Clones this DataSource.

Specified by:

clone in interface DataSource

Overrides:

clone in class Object

Returns:

the clone.

Throws:

CloneNotSupportedException - this should never happen.
