public DecimalFormat getDecimalFormat()
Returns the number formatter.- Returns:
- The number formatter.
-
setDecimalFormat
public void setDecimalFormat(DecimalFormat decimalFormat)
Sets the number formatter.- Parameters:
decimalFormat
- the number formatter.
-
getFormat
public String getFormat()

- The format string.
-
setFormat
public void setFormat(String format)
Sets the format string.- Parameters:
format
- the format string.
-
getField
public String getField()
Returns the field name.- Returns:
- The field name.
-
setField
public void setField(String field)
Sets the field name.- Parameters:
field
- the field name.
-
getFormula
public String getFormula()
Returns the formula used to compute the value of the data source.- Returns:
- the formula.
-
setFormula
public void setFormula(String formula)
Defines the formula used to compute the value of this data source.- Parameters:
formula
- the formula for the data source.
-
getNullValue
public String getNullValue()
Returns the string that represents anull
value.- Returns:
- A string.
-
setNullValue
public void setNullValue(String nullValue)
Sets the string that represents anull
value.- Parameters:
nullValue
- the string that represents anull
value.
-
getValue
public Object getValue(ExpressionRuntime runtime, ReportElement element)
Returns the current value for the data source.- Specified by:
getValue
in interfaceDataSource
- Parameters:
runtime
- the expression runtime that is used to evaluate formulas and expressions when computing the value of this filter.element
-- Returns:
- the value.
-
clone
public NumberFieldTemplate clone() throws CloneNotSupportedException
Clones the template.- Specified by:
clone
in interfaceDataSource
- Overrides:
clone
in classAbstractTemplate
- Returns:
- the clone.
- Throws:
CloneNotSupportedException
- this should never happen.
-
getDataRowDataSource
protected DataRowDataSource getDataRowDataSource()
Returns the datarow data source used in this template.- Returns:
- the datarow data source.
-
getRawValue
public Object getRawValue(ExpressionRuntime runtime, ReportElement element)
Description copied from interface:RawDataSource
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 toNumber
orDate
objects is a good idea.- Specified by:
getRawValue
in interfaceRawDataSource
- Parameters:
runtime
- the expression runtime that is used to evaluate formulas and expressions when computing the value of this filter.- Returns:
- the raw data.
-
getFormatString
public FormatSpecification getFormatString(ExpressionRuntime runtime, ReportElement element, FormatSpecification formatSpecification)
Description copied from interface:RawDataSource
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.classic.core.filter.FormatSpecification#TYPE_UNDEFINED
in that case.- Specified by:
getFormatString
in interfaceRawDataSource
- 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 theformatSpecification
parameter was not null, this given instance is reused.
