Method Detail

getHeight

public int getHeight()

Specified by:

getHeight in interface JRBand

setHeight

public void setHeight(int height)

getSplitType

public SplitTypeEnum getSplitType()

Description copied from interface: JRBand

Specifies the band split behavior.

Specified by:

getSplitType in interface JRBand

setSplitType

public void setSplitType(SplitTypeEnum splitType)

Specified by:

setSplitType in interface JRBand

getPrintWhenExpression

public JRExpression getPrintWhenExpression()

Description copied from interface: JRBand

Returns the boolean expression that specifies if the band will be displayed.

Specified by:

getPrintWhenExpression in interface JRBand

setPrintWhenExpression

public void setPrintWhenExpression(JRExpression expression)

getOrigin

public JROrigin getOrigin()

Returns the band origin, i.e. its location/role within the report (e.g. detail/title/group header/etc). The location is automatically set when the band is inserted into the report (via one of the setTitle / setPageHeader methods).

Returns:

the list of returned values.

addReturnValue

public void addReturnValue(ExpressionReturnValue returnValue)

Adds a return value to the band.

Parameters:

returnValue - the return value to be added.

getReturnValuesList

public List<ExpressionReturnValue> getReturnValuesList()

Returns the list of values to increment report variables with.

Returns:

list of ReturnValue objects

removeReturnValue

public boolean removeReturnValue(ExpressionReturnValue returnValue)

Removes a return value from the band.

Parameters:

returnValue - the return value to be removed

Returns:

true if the return value was found and removed

clone

public Object clone()

Specified by:

clone in interface JRCloneable

Overrides:

clone in class JRDesignElementGroup

hasProperties

public boolean hasProperties()

Description copied from interface: JRPropertiesHolder

Checks whether the object has any properties.

Specified by:

hasProperties in interface JRPropertiesHolder

Returns:

whether the object has any properties

getPropertiesMap

public JRPropertiesMap getPropertiesMap()

Description copied from interface: JRPropertiesHolder

this object's properties map

getParentProperties

public JRPropertiesHolder getParentProperties()

Description copied from interface: JRPropertiesHolder

Returns the parent properties holder, whose properties are used as defaults for this object.

Specified by:

getParentProperties in interface JRPropertiesHolder

Returns:

the parent properties holder, or null if no parent
