Constructor Detail

JRBaseDataRange

public JRBaseDataRange(JRDataRange dataRange)

Constructs a copy of an existing range.

Parameters:

dataRange - the range to copy

JRBaseDataRange

public JRBaseDataRange(JRDataRange dataRange,
                       ChartsBaseObjectFactory factory)

Parameters:

dataRange - the range to copy

factory - the factory to register the expressions with

Method Detail

getLowExpression

public JRExpression getLowExpression()

Description copied from interface: JRDataRange

Returns the expression that generates the lower bound of the range.

Specified by:

getLowExpression in interface JRDataRange

Returns:

the expression that generates the lower bound of the range

getHighExpression

public JRExpression getHighExpression()

Description copied from interface: JRDataRange

Returns the expression that generates the upper bound of the range.

Specified by:

getHighExpression in interface JRDataRange

Returns:

the expression that generates the upper bound of the range

collectExpressions

public void collectExpressions(JRExpressionCollector collector)

Registers all of the expressions with the collector. If the expressions have been registered with one of the report's factory they will be included when the report is compiled.

Parameters:

collector - the expression collector to use

clone
