Constructor Details

FormulaRootElement

public FormulaRootElement(FormulaDocument document)

Method Details

getText

public String getText()

Specified by:

getText in class FormulaElement

getElementIndex

public int getElementIndex(int offset)

Gets the child element index closest to the given offset. The offset is specified relative to the beginning of the document. Returns -1 if the Element is a leaf, otherwise returns the index of the Element that best represents the given location. Returns 0 if the location is less than the start offset. Returns getElementCount() - 1 if the location is greater than or equal to the end offset.

Specified by:

getElementIndex in interface Element

Overrides:

getElementIndex in class FormulaElement

Parameters:

offset - the specified offset >= 0

Returns:

the element index >= 0

getElementCount

public int getElementCount()

Gets the number of child elements contained by this element. If this element is a leaf, a count of zero is returned.

Specified by:

getElementCount in interface Element

Overrides:

getElementCount in class FormulaElement

Returns:

the number of child elements >= 0

getElement

public Element getElement(int index)

Fetches the child element at the given index.

Specified by:

getElement in interface Element

Overrides:

getElement in class FormulaElement

Parameters:

index - the specified index >= 0

Returns:

the child element. If index is invalid, return null

isLeaf

public boolean isLeaf()

Is this element a leaf element? An element that may have children, even if it currently has no children, would return false.

Specified by:

isLeaf in interface Element

Overrides:

isLeaf in class FormulaElement

Returns:

true if a leaf element else false

getName

public String getName()

Fetches the name of the element. If the element is used to represent some type of structure, this would be the type name.

Returns:

the element name

setElements

public void setElements(FormulaElement[] elements)

setElement

public void setElement(int index,
 FormulaElement element)

insertElement

 FormulaElement element)

removeElement

revalidateStructure

public void revalidateStructure()

revalidateNodePositions

public void revalidateNodePositions()

print

public void print()

clear

public void clear()

replace

public void replace(FormulaElement oldElement,
 FormulaTextElement formulaTextElement,
 boolean hasDummyParams)

insert

public void insert(FormulaElement oldElement,
 FormulaTextElement formulaTextElement)
