class wpilib.SmartDashboard¶

Bases: pybind11_builtins.pybind11_object

static clearFlags(key: str, flags: int) → None¶

Clears flags on the specified key in this table. The key can not be null.

Parameters

key – the key name
flags – the flags to clear (bitmask)

static clearPersistent(key: str) → None¶

Stop making a key’s value persistent through program restarts. The key cannot be null.

Parameters: key – the key name

static containsKey(key: str) → bool¶

Determines whether the given key is in this table.

Parameters: key – the key to search for
Returns: true if the table as a value assigned to the given key

static delete(key: str) → None¶

Deletes the specified key in this table.

Parameters: key – the key name

static getBoolean(keyName: str, defaultValue: object) → object¶

Returns the value at the specified key.

If the key is not found, returns the default value.

Parameters

keyName – the key
defaultValue – the default value to set if key doesn’t exist

Returns

the value

static getBooleanArray(key: str, defaultValue: object) → object¶

Returns the boolean array the key maps to.

If the key does not exist or is of different type, it will return the default value.

Parameters

key – The key to look up.
defaultValue – The value to be returned if no value is found.

Returns

the value associated with the given key or the given default value if there is no value associated with the key

@note This makes a copy of the array. If the overhead of this is a concern, use GetValue() instead.

@note The returned array is std::vector<int> instead of std::vector<bool> because std::vector<bool> is special-cased in C++. 0 is false, any non-zero value is true.

static getData(keyName: str) → wpiutil._wpiutil.Sendable¶

Returns the value at the specified key.

Parameters: keyName – the key
Returns: the value

static getEntry(key: str) → _pyntcore._ntcore.NetworkTableEntry¶

This is useful if an entry is used often, or is read and then modified.

Parameters: key – the key
Returns: the entry for the key

static getFlags(key: str) → int¶

Returns the flags for the specified key.

Parameters: key – the key name
Returns: the flags, or 0 if the key is not defined

static getKeys(types: int = 0) → List[str]¶

Parameters: types – bitmask of types; 0 is treated as a “don’t care”.
Returns: keys currently in the table

static getNumber(keyName: str, defaultValue: object) → object¶

Returns the value at the specified key.

If the key is not found, returns the default value.

Parameters

keyName – the key
defaultValue – the default value to set if the key doesn’t exist

Returns

the value

static getNumberArray(key: str, defaultValue: object) → object¶

Returns the number array the key maps to.

If the key does not exist or is of different type, it will return the default value.

Parameters

key – The key to look up.
defaultValue – The value to be returned if no value is found.

Returns

the value associated with the given key or the given default value if there is no value associated with the key

@note This makes a copy of the array. If the overhead of this is a concern, use GetValue() instead.

static getRaw(key: str, defaultValue: object) → object¶

Returns the raw value (byte array) the key maps to.

If the key does not exist or is of different type, it will return the default value.

Parameters

key – The key to look up.
defaultValue – The value to be returned if no value is found.

Returns

the value associated with the given key or the given default value if there is no value associated with the key

@note This makes a copy of the raw contents. If the overhead of this is a concern, use GetValue() instead.

static getString(keyName: str, defaultValue: object) → object¶

Returns the value at the specified key.

If the key is not found, returns the default value.

Parameters

keyName – the key
defaultValue – the default value to set if the key doesn’t exist

defaultValue – The value to be returned if no value is found.

Returns

the value associated with the given key or the given default value if there is no value associated with the key

@note This makes a copy of the array. If the overhead of this is a concern, use GetValue() instead.

static getValue(keyName: str) → _pyntcore._ntcore.Value¶

Retrieves the complex value (such as an array) in this table into the complex data object.

Parameters: keyName – the key

static init() → None¶

static isPersistent(key: str) → bool¶

Returns whether the value is persistent through program restarts. The key cannot be null.

Parameters: key – the key name

static postListenerTask(task: Callable[[], None]) → None¶

Posts a task from a listener to the ListenerExecutor, so that it can be run synchronously from the main loop on the next call to updateValues().

Parameters: task – The task to run synchronously from the main thread.

static putBoolean(keyName: str, value: bool) → bool¶

Maps the specified key to the specified value in this table.

The value can be retrieved by calling the get method with a key that is equal to the original key.

Parameters

keyName – the key
value – the value

Returns

False if the table key already exists with a different type

static putBooleanArray(key: str, value: List[int]) → bool¶

Put a boolean array in the table.

Parameters

key – the key to be assigned to
value – the value that will be assigned

Returns

False if the table key already exists with a different type

@note The array must be of int’s rather than of bool’s because std::vector<bool> is special-cased in C++. 0 is false, any non-zero value is true.

static putData(*args, **kwargs)¶

Overloaded function.

putData(key: str, data: wpiutil._wpiutil.Sendable) -> None

Maps the specified key to the specified value in this table.

The value can be retrieved by calling the get method with a key that is equal to the original key.
