Number tree is a kind of common data structure in PDF. A number tree is similar to a number tree, except that keys in a number tree are integers instead of strings and are sorted in ascending numerical order. Number tree has following characteristics:
Class PDFNumberTree is used to be associated with an existing number tree with specified type or create one. It offers functions to get key-value pairs in the number tree, and set/add/remove any key-value pair. Currently, class PDFNumberTree can be associated with following number tree defined in PDF document:
def FoxitPDFSDKPython3.PDFNumberTree.PDFNumberTree | ( | other | ) |
Constructor, with another PDF number tree object.
[in] | other | Another PDF number tree object. |
def FoxitPDFSDKPython3.PDFNumberTree.GetObj | ( | number | ) |
Get the value (as PDF object) of a specified key integer.
[in] | number | An integer as the key. |
def FoxitPDFSDKPython3.PDFNumberTree.GetType | ( | ) |
Get the type of current number tree.
def FoxitPDFSDKPython3.PDFNumberTree.HasNumber | ( | number | ) |
Check if the specified key integer exists in current number tree.
[in] | number | An integer that represents the key to be checked. |
def FoxitPDFSDKPython3.PDFNumberTree.IsEmpty | ( | ) |
Check whether current object is empty or not.
When the current object is empty, that means current object is useless.
def FoxitPDFSDKPython3.PDFNumberTree.RemoveAllObjs | ( | ) |
Remove all key integers from current number tree, along with theirs value (as PDF object).
def FoxitPDFSDKPython3.PDFNumberTree.RemoveObj | ( | number | ) |
Remove a key integer from current number tree, along with its value (as PDF object).
If the input key integer does not exist in current number tree, this function will return true directly.
[in] | number | An integer as the key to be removed. |
def FoxitPDFSDKPython3.PDFNumberTree.SetObj | ( | number, | |
pdf_object | |||
) |
Set the value (as PDF object) of a specified key integer. If the key integer does not exist, it will be added to current number tree with the value.
[in] | number | An integer as the key. |
[in] | pdf_object | A PDF object to be set as the key's value. It should not be null. The type of this PDF object should match current number tree; otherwise, the input PDF object is invalid. Please refer to comment of class PDFNumberTree for more details. User should not release this PDF object after this function succeeds. |
