ItemHideFunction
public class ItemHideFunction extends AbstractFunction implements PageEventListener(Code)
	The ItemHideFunction hides equal values in a group. Only the first changed value is printed. This function uses the property `element` to define the name of the element in the ItemBand that should be made visible or invisible by this function. The property `field` defines the field in the datasource or the expression which should be used to determine the visibility. author: Thomas Morgner

Constructor Summary
public	ItemHideFunction() Constructs an unnamed function.
public	ItemHideFunction(String name) Constructs a named function.

Method Summary
public String	getElement() Returns the name of the element in the item band that should be set visible/invisible.
public String	getField() Returns the field used by the function.
public Expression	getInstance() Return a completly separated copy of this function.
public Object	getValue() Returns the function value, in this case the visibility of the defined element.
public boolean	isIgnoreGroupBreaks() Returns whether a group start resets the visiblity of the element.
public boolean	isIgnorePageBreaks() Returns whether a page start resets the visiblity of the element.
public void	itemsAdvanced(ReportEvent event) Receives notification that a row of data is being processed.
public void	itemsStarted(ReportEvent event) Resets the state of the function when a new ItemGroup has started.
public void	pageFinished(ReportEvent event) Receives notification that a page is completed.
public void	pageStarted(ReportEvent event) Receives notification that a new page is being started.
public void	reportInitialized(ReportEvent event) Receives notification that the report has started.
public void	setElement(String name) Sets the name of the element in the item band that should be set visible/invisible.
public void	setField(String field) Sets the field name for the function.
public void	setIgnoreGroupBreaks(boolean ignoreGroupBreaks) Defines whether a group start resets the visiblity of the element.
public void	setIgnorePageBreaks(boolean ignorePageBreaks) Returns whether a page start resets the visiblity of the element.

Constructor Detail

ItemHideFunction
public ItemHideFunction()(Code)
	Constructs an unnamed function. Make sure to set the function name before it is used, or function initialisation will fail.

ItemHideFunction
public ItemHideFunction(String name)(Code)
	Constructs a named function. The field must be defined before using the function. Parameters: name - The function name.

Method Detail

getElement
public String getElement()(Code)
	Returns the name of the element in the item band that should be set visible/invisible. The element name.

getField
public String getField()(Code)
	Returns the field used by the function. The field name corresponds to a column name in the report's data-row. The field name.

getInstance
public Expression getInstance()(Code)
	Return a completly separated copy of this function. The copy does no longer share any changeable objects with the original function. a copy of this function.

getValue
public Object getValue()(Code)
	Returns the function value, in this case the visibility of the defined element. The function value.

isIgnoreGroupBreaks
public boolean isIgnoreGroupBreaks()(Code)
	Returns whether a group start resets the visiblity of the element. false, if group breaks reset the visiblity, true otherwise.

isIgnorePageBreaks
public boolean isIgnorePageBreaks()(Code)
	Returns whether a page start resets the visiblity of the element. false, if page breaks reset the visiblity, true otherwise.

itemsAdvanced
public void itemsAdvanced(ReportEvent event)(Code)
	Receives notification that a row of data is being processed. Reads the data from the field defined for this function and hides the field if the value is equal to the last value and the this is not the first row of the item group. Parameters: event - Information about the event.

itemsStarted
public void itemsStarted(ReportEvent event)(Code)
	Resets the state of the function when a new ItemGroup has started. Parameters: event - the report event.

pageFinished
public void pageFinished(ReportEvent event)(Code)
	Receives notification that a page is completed. Parameters: event - The event.

pageStarted
public void pageStarted(ReportEvent event)(Code)
	Receives notification that a new page is being started. Parameters: event - The event.

reportInitialized
public void reportInitialized(ReportEvent event)(Code)
	Receives notification that the report has started. Parameters: event - the event.

setElement
public void setElement(String name)(Code)
	Sets the name of the element in the item band that should be set visible/invisible. Parameters: name - the element name (must not be null).

setField
public void setField(String field)(Code)
	Sets the field name for the function. The field name corresponds to a column name in the report's data-row. Parameters: field - the field name.

setIgnoreGroupBreaks
public void setIgnoreGroupBreaks(boolean ignoreGroupBreaks)(Code)
	Defines whether a group start resets the visiblity of the element. Parameters: ignoreGroupBreaks - false, if group breaks reset the visiblity, true otherwise.

setIgnorePageBreaks
public void setIgnorePageBreaks(boolean ignorePageBreaks)(Code)
	Returns whether a page start resets the visiblity of the element. Parameters: ignorePageBreaks - false, if page breaks reset the visiblity, true otherwise.
