Field Summary
final public static byte PERCENTAGE_TYPE_GRAND_TOTAL
     Percentage type indicating that the value will be calculated as percentage of the grand total value.
final public static byte PERCENTAGE_TYPE_NONE
     Percentage type indicating that the value will not be calculated as a percentage.

Method Summary
public byte getCalculation()
     Returns the calculation type which will be performed on the measure values.
public Class getIncrementerFactoryClass()
     Returns the incrementer factory class.
public String getIncrementerFactoryClassName()
     Returns the incrementer factory class name.
public String getName()
     Returns the name of the measure.
public Class getPercentageCalculatorClass()
     Returns the percentage calcualtor class.
public String getPercentageCalculatorClassName()
     Returns the percentage calculator class name.
public byte getPercentageOfType()
     Returns the percentage calculation type performed on this measure.
public Class getValueClass()
     Returns the value class of this measure.
public String getValueClassName()
     Returns the name of the value class for this measure.
public JRExpression getValueExpression()
     Returns the measure expression.
public JRVariable getVariable()
     Returns the variable associated with this measure.
The variable can be used inside the crosstab data cells as the measure value.

Field Detail
PERCENTAGE_TYPE_GRAND_TOTAL
final public static byte PERCENTAGE_TYPE_GRAND_TOTAL(Code)
Percentage type indicating that the value will be calculated as percentage of the grand total value.

PERCENTAGE_TYPE_NONE
final public static byte PERCENTAGE_TYPE_NONE(Code)
Percentage type indicating that the value will not be calculated as a percentage.

Method Detail
getCalculation
public byte getCalculation()(Code)
Returns the calculation type which will be performed on the measure values.
The incrementer factory associated with this measure will create an incrementer which will sum the measure values.
The possible calculation type are the same as the ones used for variables (see JRVariable.getCalculation JRVariable.getCalculation() with the exception of JRVariable.CALCULATION_SYSTEM JRVariable.CALCULATION_SYSTEM . the calculation type which will be performed on the measure values

See Also:   net.sf.jasperreports.engine.fill.JRExtendedIncrementerFactory
See Also:   net.sf.jasperreports.engine.fill.JRExtendedIncrementer

getIncrementerFactoryClass
public Class getIncrementerFactoryClass()(Code)
Returns the incrementer factory class. the incrementer factory class
See Also:   JRCrosstabMeasure.getIncrementerFactoryClassName()

getIncrementerFactoryClassName
public String getIncrementerFactoryClassName()(Code)
Returns the incrementer factory class name.
Crosstab measures require extended incrementers, therefore the incrementer class should implement net.sf.jasperreports.engine.fill.JRExtendedIncrementerFactory JRExtendedIncrementerFactory . the incrementer factory class name

getName
public String getName()(Code)
Returns the name of the measure. the name of the measure
See Also:   JRCrosstabMeasure.getVariable()

getPercentageCalculatorClass
public Class getPercentageCalculatorClass()(Code)
Returns the percentage calcualtor class. the percentage calcualtor class

getPercentageCalculatorClassName
public String getPercentageCalculatorClassName()(Code)
Returns the percentage calculator class name. the percentage calculator class name

getPercentageOfType
public byte getPercentageOfType()(Code)
Returns the percentage calculation type performed on this measure.
Currently, only percentage out of grand total is supported.
The possible values are:

JRCrosstabMeasure.PERCENTAGE_TYPE_NONE PERCENTAGE_TYPE_NONE

JRCrosstabMeasure.PERCENTAGE_TYPE_GRAND_TOTAL PERCENTAGE_TYPE_GRAND_TOTAL

If percentage calculation is required, the value class should be one of the built-in supported percentage types or the percentage calculator class should be specified. the percentage calculation type

See Also:   JRCrosstabMeasure.getPercentageCalculatorClassName()

getValueClass
public Class getValueClass()(Code)
Returns the value class of this measure. the value class of this measure

getValueClassName
public String getValueClassName()(Code)
Returns the name of the value class for this measure. the name of the value class for this measure

getValueExpression
public JRExpression getValueExpression()(Code)
Returns the measure expression. the measure expression

getVariable
public JRVariable getVariable()(Code)
Returns the variable associated with this measure.
The variable can be used inside the crosstab data cells as the measure value. The variable has the same name and value class as the measure. the variable associated with this measure
