Class ArrayPtg

java.lang.Object

org.apache.poi.ss.formula.ptg.Ptg

org.apache.poi.ss.formula.ptg.ArrayPtg

public final class ArrayPtg
extends Ptg

ArrayPtg - handles arrays The ArrayPtg is a little weird, the size of the Ptg when parsing initially only includes the Ptg sid and the reserved bytes. The next Ptg in the expression then follows. It is only after the "size" of all the Ptgs is met, that the ArrayPtg data is actually held after this. So Ptg.createParsedExpression keeps track of the number of ArrayPtg elements and need to parse the data upto the FORMULA record size.

Constructor Detail

ArrayPtg

public ArrayPtg(Object[][] values2d)

Parameters:

values2d - array values arranged in rows

Method Detail

getTokenArrayValues

public Object[][] getTokenArrayValues()

Returns:

2-d array (inner index is rowIx, outer index is colIx)

isBaseToken

public boolean isBaseToken()

Specified by:

isBaseToken in class Ptg

Returns:

false if this token is classified as 'reference', 'value', or 'array'

toString

public String toString()

Description copied from class: Ptg

Overridden toString method to ensure object hash is not printed. This helps get rid of gratuitous diffs when comparing two dumps Subclasses may output more relevant information by overriding this method

Overrides:

toString in class Ptg

write

public void write(LittleEndianOutput out)

Specified by:

write in class Ptg

writeTokenValueBytes

public int writeTokenValueBytes(LittleEndianOutput out)

getRowCount

public int getRowCount()

getColumnCount

public int getColumnCount()

getSize

public int getSize()

This size includes the size of the array Ptg plus the Array Ptg Token value size

Specified by:

getSize in class Ptg

Returns:

the encoded length of this Ptg, including the initial Ptg type identifier byte.

toFormulaString

public String toFormulaString()

Description copied from class: Ptg

return a string representation of this token alone

Specified by:

toFormulaString in class Ptg

getDefaultOperandClass

public byte getDefaultOperandClass()

Specified by:

getDefaultOperandClass in class Ptg
