Detailed Description

Job class for caching textures.

Handles loading and caching of textures.

Member Function Documentation

◆ CacheTexture()

bool CTextureCacheJob::CacheTexture ( std::unique_ptr< CTexture > * texture = nullptr )

retrieve a hash for the given image Combines the size, ctime and mtime of the image file into a "unique" hash

Parameters

url	location of the image

Returns: a hash string for this image

◆ DoWork()

bool CTextureCacheJob::DoWork ( )

overridevirtual

Main workhorse function of CJob instances.

All CJob subclasses must implement this function, performing all processing. Once this function is complete, the OnJobComplete() callback is called, and the job is then destroyed.

See also: CJobManager, IJobCallback::OnJobComplete()

Implements CJob.

◆ GetType()

const char * CTextureCacheJob::GetType ( ) const

inlineoverridevirtual

Function that returns the type of job.

CJob subclasses may optionally implement this function to specify the type of job. This is useful for the CJobManager::AddLIFOJob() routine, which preempts similar jobs with the new job.

Returns: a unique character string describing the job.

Reimplemented from CJob.

◆ operator==()

bool CTextureCacheJob::operator== ( const CJob * job ) const

overridevirtual

Reimplemented from CJob.

◆ ResizeTexture()

bool CTextureCacheJob::ResizeTexture	(	const std::string &	url,
		uint8_t *&	result,
		size_t &	result_size )
