Detailed Description

Data source for data that is not memory mapped (has no natural address).

This data source can only manage a single block of data, which has no associated address. It acts as its own Segment.

Member Function Documentation

uint32_t UnmappedDataSource::getBaseAddress ( )

virtual

Returns the address associated with the segment.

The unmapped datasource as segment's base address is a function of the data target. If the target is not NULL, then the segment's base address is simply the target's beginAddress. Otherwise, if no target has been set, then the base address returned is 0.

Reimplemented from blfwk::DataSource::Segment.

void UnmappedDataSource::setData	(	const uint8_t *	data,
		unsigned	length
	)

Sets the source's data.

Makes a copy of data that is freed when the data source is destroyed. The caller does not have to maintain data after this call returns.
