Method Detail

validateConstructorArguments

protected void validateConstructorArguments(SpreadsheetWorksheet worksheet,
                                            int index)

This method ensures 1) given worksheet is not null 2) index is less than value returned by SpreadsheetWorksheet#getColumnStartingIndex() - otherwise an IllegalArgumentException is thrown.

Parameters:

worksheet -

index -

getWorksheet

public SpreadsheetWorksheet getWorksheet()

Returns:

the worksheet this column belongs to

getIndex

public int getIndex()

Returns:

the index of the column

getName

public String getName()

Returns:

the name of the column

getAlias

public String getAlias()

Returns:

the alias of the column

getDataType

public SpreadsheetDataType getDataType()

Returns:

the data type of the column

isMany

public boolean isMany()

Returns:

the multiplicity of the column i.e. whether it may contain multiple delimiter-separated values

isNotMany

public boolean isNotMany()

Returns:

true if this column may not store multiple values in a single cell

getDelimiter

public String getDelimiter()

Returns:

the delimiter used for separating the individual cell values. This is useful if a column may contain multiple values

setName

public void setName(String name)

Parameters:

name - the name of the column

setAlias

public void setAlias(String alias)

Parameters:

alias - the alias of the column

setDataType

public void setDataType(SpreadsheetDataType dataType)

Parameters:

dataType - the data type of the column

setMany

public void setMany(boolean many)

Parameters:

many - the multiplicity of the column

setDelimiter

public void setDelimiter(String delimiter)

Parameters:

delimiter - the delimiter used for separating the values stored in individual cells of the column

isIdentifiableBy

public boolean isIdentifiableBy(String identifier)

Column can be identified either by its name, alias or prefixed column index

Parameters:

identifier -

Returns:

true if column can be identified by the identifier, false otherwise

getPrefixedIndex

public String getPrefixedIndex()

This method returns the index of this column prefixed by SpreadsheetConstants.PREFIX_COLUMN.

Returns:

prefixed index

isValidIndex

public boolean isValidIndex(String identifier)

This method checks if the index embedded within the provided prefixed column index is equal to the index of this column i.e. it will always return true if identifier is equal to the output of getPrefixedIndex().

Parameters:

identifier -

Returns:

true if index of the column equals the embedded index

getIdentifier

public String getIdentifier()

Returns:

an identifier of the column. If name is set then it is returned, otherwise if alias is set then it is returned. If neither is set then prefixed column index is returned

toString

public String toString()

Overrides:

toString in class Object
