Method Detail

getSheetName

public java.lang.String getSheetName()

Get the sheets name which this named range is referenced to

Specified by:

getSheetName in interface Name

Returns:

sheet name, which this named range referred to

getNameName

public java.lang.String getNameName()

Description copied from interface: Name

Gets the name of the named range

Specified by:

getNameName in interface Name

Returns:

text name of this defined name

setNameName

public void setNameName(java.lang.String nameName)

Sets the name of the named range

The following is a list of syntax rules that you need to be aware of when you create and edit names.

• Valid characters The first character of a name must be a letter, an underscore character (_), or a backslash (\). Remaining characters in the name can be letters, numbers, periods, and underscore characters.
• Cell references disallowed Names cannot be the same as a cell reference, such as Z$100 or R1C1.
• Spaces are not valid Spaces are not allowed as part of a name. Use the underscore character (_) and period (.) as word separators, such as, Sales_Tax or First.Quarter.
• Name length A name can contain up to 255 characters.
• Case sensitivity Names can contain uppercase and lowercase letters.

A name must always be unique within its scope. POI prevents you from defining a name that is not unique within its scope. However you can use the same name in different scopes. Example:

 //by default names are workbook-global
 HSSFName name;
 name = workbook.createName();
 name.setNameName("sales_08");

 name = workbook.createName();
 name.setNameName("sales_08"); //will throw an exception: "The workbook already contains this name (case-insensitive)"

 //create sheet-level name
 name = workbook.createName();
 name.setSheetIndex(0); //the scope of the name is the first sheet
 name.setNameName("sales_08");  //ok

 name = workbook.createName();
 name.setSheetIndex(0);
 name.setNameName("sales_08");  //will throw an exception: "The sheet already contains this name (case-insensitive)"

 

Specified by:

Parameters:

nameName - named range name to set

Throws:

java.lang.IllegalArgumentException - if the name is invalid or the name already exists (case-insensitive)
