      • getCount

        public int getCount()
        
        Gets number of items in the collection.

        Example:

        Enumerates through all built-in and custom properties in a document using indexed access.
        String fileName = getMyDir() + "Properties.doc";
        Document doc = new Document(fileName);
        
        System.out.println(MessageFormat.format("1. Document name: {0}", fileName));
        
        System.out.println("2. Built-in Properties");
        for (int i = 0; i < doc.getBuiltInDocumentProperties().getCount(); i++)
        {
            DocumentProperty docProperty = doc.getBuiltInDocumentProperties().get(i);
            System.out.println(MessageFormat.format("{0}({1}) : {2}", docProperty.getName(), docProperty.getType(), docProperty.getValue()));
        }
        
        System.out.println("3. Custom Properties");
        for (int i = 0; i < doc.getCustomDocumentProperties().getCount(); i++)
        {
            DocumentProperty docProperty = doc.getCustomDocumentProperties().get(i);
            System.out.println(MessageFormat.format("{0}({1}) : {2}", docProperty.getName(), docProperty.getType(), docProperty.getValue()));
        }
      • get

        public DocumentProperty get(int index)
        
        Returns a DocumentProperty object by index.

        Note: In Java this method is slow because iterates over all nodes.

        Parameters:
        index - Zero-based index of the DocumentProperty to retrieve.

        Example:

        Enumerates through all built-in and custom properties in a document using indexed access.
        String fileName = getMyDir() + "Properties.doc";
        Document doc = new Document(fileName);
        
        System.out.println(MessageFormat.format("1. Document name: {0}", fileName));
        
        System.out.println("2. Built-in Properties");
        for (int i = 0; i < doc.getBuiltInDocumentProperties().getCount(); i++)
        {
            DocumentProperty docProperty = doc.getBuiltInDocumentProperties().get(i);
            System.out.println(MessageFormat.format("{0}({1}) : {2}", docProperty.getName(), docProperty.getType(), docProperty.getValue()));
        }
        
        System.out.println("3. Custom Properties");
        for (int i = 0; i < doc.getCustomDocumentProperties().getCount(); i++)
        {
            DocumentProperty docProperty = doc.getCustomDocumentProperties().get(i);
            System.out.println(MessageFormat.format("{0}({1}) : {2}", docProperty.getName(), docProperty.getType(), docProperty.getValue()));
        }
      • get

        public DocumentProperty get(java.lang.String name)
        
        Returns a DocumentProperty object by the name of the property.

        Returns null if a property with the specified name is not found.

        Parameters:
        name - The case-insensitive name of the property to retrieve.

        Example:

        Retrieves a custom document property by name.
        Document doc = new Document(getMyDir() + "Properties.doc");
        
        DocumentProperty docProperty = doc.getCustomDocumentProperties().get("Authorized Date");
        
        if (docProperty != null)
        {
            System.out.println(docProperty.toDateTime());
        } else
        {
            System.out.println("The document is not authorized. Authorizing...");
            doc.getCustomDocumentProperties().add("AuthorizedDate", new Date());
        }
