Detailed Description

Type conversion methods for CPTNumericData.

Method Documentation

convertData:dataType:toData:dataType:

- (void) convertData:		(nonnull NSData *)	sourceData
dataType:		(nonnull CPTNumericDataType *)	sourceDataType
toData:		(nonnull NSMutableData *)	destData
dataType:		(nonnull CPTNumericDataType *)	destDataType

Copies a data buffer and converts the data to a new data type without changing the byte order.

The data is assumed to be in host byte order and no byte order conversion is performed.

Parameters

sourceData	The source data buffer.
sourceDataType	The data type of the source.
destData	The destination data buffer.
destDataType	The new data type.

Extends class CPTNumericData.

dataByConvertingToDataType:

- (nonnull CPTNumericData *) dataByConvertingToDataType:

(CPTNumericDataType)

newDataType

Copies the current numeric data and converts the data to a new data type.

Parameters

newDataType

The new data type.

Returns

A copy of the current numeric data converted to the new data type.

Extends class CPTNumericData.

dataByConvertingToType:sampleBytes:byteOrder:

- (nonnull CPTNumericData *) dataByConvertingToType:		(CPTDataTypeFormat)	newDataType
sampleBytes:		(size_t)	newSampleBytes
byteOrder:		(CFByteOrder)	newByteOrder

Copies the current numeric data and converts the data to a new data type.

Parameters

newDataType	The new data type format.
newSampleBytes	The number of bytes used to store each sample.
newByteOrder	The new byte order.

Returns

A copy of the current numeric data converted to the new data type.

Extends class CPTNumericData.

swapByteOrderForData:sampleSize:

- (void) swapByteOrderForData:		(nonnull NSMutableData *)	sourceData
sampleSize:		(size_t)	sampleSize

Swaps the byte order for each sample stored in a data buffer.

Parameters

sourceData	The data buffer.
sampleSize	The number of bytes in each sample stored in sourceData.

Extends class CPTNumericData.
