Detailed Description

Dynamic (run-time) read-only access to a serialized raw struct.

Constructor & Destructor Documentation

DynamicStruct()

wpi::DynamicStruct::DynamicStruct ( const StructDescriptor *  desc, std::span< const uint8_t >  data  )

inline

Constructs a new dynamic struct.

Note: the passed data is a span; no copy is made, so it's necessary for the lifetime of the referenced data to be longer than this object.

Parameters

desc	struct descriptor
data	serialized data

Member Function Documentation

FindField()

const StructFieldDescriptor * wpi::DynamicStruct::FindField ( std::string_view  name ) const

inline

Gets a struct field descriptor by name.

Parameters

name	field name

Returns

field descriptor, or nullptr if no field with that name exists

GetBoolField()

bool wpi::DynamicStruct::GetBoolField ( const StructFieldDescriptor *  field, size_t  arrIndex = 0  ) const

inline

Gets the value of a boolean field.

Parameters

field	field descriptor
arrIndex	array index (must be less than field array size)

Returns

field value

GetData()

std::span< const uint8_t > wpi::DynamicStruct::GetData ( ) const

inline

Gets the serialized data.

Returns

data

GetDescriptor()

const StructDescriptor * wpi::DynamicStruct::GetDescriptor ( ) const

inline

Gets the struct descriptor.

Returns

struct descriptor

GetDoubleField()

double wpi::DynamicStruct::GetDoubleField ( const StructFieldDescriptor *  field, size_t  arrIndex = 0  ) const

inline

Gets the value of a double field.

Parameters

field	field descriptor
arrIndex	array index (must be less than field array size)

Returns

field value

GetFloatField()

float wpi::DynamicStruct::GetFloatField ( const StructFieldDescriptor *  field, size_t  arrIndex = 0  ) const

inline

Gets the value of a float field.

Parameters

field	field descriptor
arrIndex	array index (must be less than field array size)

Returns

field value

GetIntField()

int64_t wpi::DynamicStruct::GetIntField ( const StructFieldDescriptor *  field, size_t  arrIndex = 0  ) const

inline

Gets the value of a signed integer field.

Parameters

field	field descriptor
arrIndex	array index (must be less than field array size)

Returns

field value

GetStringField()

std::string_view wpi::DynamicStruct::GetStringField ( const StructFieldDescriptor *  field ) const

inline

Gets the value of a char or char array field.

Parameters

field

field descriptor

Returns

field value

GetStructField()

DynamicStruct wpi::DynamicStruct::GetStructField ( const StructFieldDescriptor *  field, size_t  arrIndex = 0  ) const

inline

Gets the value of a struct field.

Parameters

field	field descriptor
arrIndex	array index (must be less than field array size)

Returns

field value

GetUintField()

uint64_t wpi::DynamicStruct::GetUintField ( const StructFieldDescriptor *  field, size_t  arrIndex = 0  ) const

inline

Gets the value of an unsigned integer field.

Parameters

field	field descriptor
arrIndex	array index (must be less than field array size)

Returns

field value
