## org.apache.poi.ss.formula.ptg
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.

Field Detail

### sid

    public static final byte sid

  Constant Field Values

### PLAIN_TOKEN_SIZE

    public static final int PLAIN_TOKEN_SIZE

  The size of the plain tArray token written within the standard formula tokens (not including the data which comes after all formula tokens)

  See Also:
    Constant Field Values

Constructor Detail

### ArrayPtg

    public ArrayPtg(java.lang.Object[][] values2d)

Parameters:
  `values2d` - array values arranged in rows

Method Detail

### getTokenArrayValues

    public java.lang.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 java.lang.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 java.lang.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`
