MeasureValue

public MeasureValue()

Initializes the value.

Method Detail

init

protected void init()

addValue

public void addValue(java.lang.Object addValue)
              throws JRException

Accumulates a value.

Parameters:

addValue - the value

Throws:

JRException

addValue

public void addValue(MeasureDefinition.MeasureValue measureValue)
              throws JRException

Accumulates another measure value.

This is used for total calculations, when two accumulated values are combined into a total.

Parameters:

measureValue - the measure value

Throws:

JRException

getValue

public java.lang.Object getValue()

Description copied from interface: JRCalculable

Returns the value of the calculable object.

Specified by:

getValue in interface JRCalculable

Returns:

the value

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

setHelper

public MeasureDefinition.MeasureValue setHelper(MeasureDefinition.MeasureValue helperVariable,
                                                byte type)

Sets a helper variable.

Parameters:

helperVariable - the helper variable

type - the helper type

Returns:

the previous helper variable for the type

isInitialized

public boolean isInitialized()

Description copied from interface: JRCalculable

Returns true if and only if the calculable object was only initialized and not incremented.

Specified by:

isInitialized in interface JRCalculable

Returns:

true if and only if the calculable object was only initialized and not incremented

getIncrementedValue

public java.lang.Object getIncrementedValue()

Description copied from interface: JRCalculable

Returns the incremented value of the calculable object.

Specified by:

getIncrementedValue in interface JRCalculable

Returns:

the incremented value

getHelperVariable

public JRCalculable getHelperVariable(byte helperType)

Description copied from interface: JRCalculable

Returns a helper variable.

Specified by:

getHelperVariable in interface JRCalculable

Parameters:

helperType - the desired helper variable type

Returns:

the helper variable

setInitialized

public void setInitialized(boolean isInitialized)

Description copied from interface: JRCalculable

Sets the initialized flag for this calculable object.

Specified by:

setInitialized in interface JRCalculable

Parameters:

isInitialized - the initialized flag
