A library containing most of the core functionality and data types used in Grafana.
Classes
| Class | Description |
|---|---|
| AppendedVectors | This may be more trouble than it is worth. This trades some computation time for RAM – rather than allocate a new array the size of all previous arrays, this just points the correct index to their original array values |
| AppPlugin | |
| ArrayVector | |
| AsNumberVector | This will force all values to be numbers |
| BinaryOperationVector | |
| CircularDataFrame | This dataframe can have values constantly added, and will never exceed the given capacity |
| CircularVector | Circular vector uses a single buffer to capture a stream of values overwriting the oldest value on add.This supports adding to the ‘head’ or ‘tail’ and will grow the buffer to match a configured capacity. |
| ConstantVector | |
| CSVReader | |
| DataFrameView | (BETA) This abstraction will present the contents of a DataFrame as if it were a well typed javascript object Vector. |
| DataSourceApi | The main data source abstraction interface, represents an instance of a data sourceAlthough this is a class, datasource implementations do not yet need to extend it. As such, we can not yet add functions with default implementations. |
| DataSourcePlugin | |
| FieldCache | |
| FieldConfigEditorBuilder | Fluent API for declarative creation of field config option editors |
| FieldConfigOptionsRegistry | |
| FormattedVector | |
| GrafanaPlugin | |
| IndexVector | IndexVector is a simple vector implementation that returns the index value for each element in the vector. It is functionally equivolant a vector backed by an array with values: [0,1,2,…,length-1] |
| LanguageProvider | |
| MutableDataFrame | |
| PanelOptionsEditorBuilder | Fluent API for declarative creation of panel options |
| PanelPlugin | |
| Registry | |
| SortedVector | Values are returned in the order defined by the input parameter |
| SystemDateFormatsState |

| dateTimeParse | Helper function to parse a number, text or Date to a DateTime value. If a timeZone is supplied the incoming value is parsed with that timeZone as a base. The only exception to this is if the passed value is in a UTC-based format. Then it will use UTC as the base. If no format is specified the current system format will be assumed.It can also parse the Grafana quick date and time format, e.g. now-6h will be parsed as Date.now() - 6 hours and returned as a valid DateTime value.If no options are supplied, then default values are used.
