Fields

end_char_idx (Optional[int])
metadata_seperator (str)
metadata_template (str)
start_char_idx (Optional[int])
text (str)
text_template (str)

field end_char_idx: Optional[int] = None#: End char index of the node.

field metadata_seperator: str = '\n'#: Separator between metadata fields when converting to string.

field metadata_template: str = '{key}: {value}'#: Template for how metadata is formatted, with {key} and {value} placeholders.

field start_char_idx: Optional[int] = None#: Start char index of the node.

field text: str = ''#: Text content of the node.

field text_template: str = '{metadata_str}\n\n{content}'#: Template for how text is formatted, with {content} and {metadata_str} placeholders.

classmethod class_name() → str#

Get the class name, used as a unique ID in serialization.

This provides a key that makes serialization robust against actual class name changes.

get_content(metadata_mode: MetadataMode = MetadataMode.NONE) → str#: Get object content.

get_metadata_str(mode: MetadataMode = MetadataMode.ALL) → str#: Metadata info string.

get_node_info() → Dict[str, Any]#: Get node info.

get_text() → str#

classmethod get_type() → str#: Get Object type.

set_content(value: str) → None#: Set the content of the node.

property hash: str#: Get hash of node.

property node_info: Dict[str, Any]#

Get node info.
