Detailed Description

Base class for all resource types to be managed by the ResourceManager class.

Member Function Documentation

Clone()

virtual Resource* KatanaEngine::Resource::Clone ( )

inlineprotectedvirtual

Clones a resource.

Returns

Returns a pointer to a clone if the resource is cloneable. Otherwise a pointer to "this" is returned.

Reimplemented in KatanaEngine::Animation.

GetResourceID()

unsigned short KatanaEngine::Resource::GetResourceID ( ) const

inline

Gets the ID of the resource.

Returns

The id of the resource.

GetResourceManager()

ResourceManager* KatanaEngine::Resource::GetResourceManager ( )

inlineprotected

Gets a pointer to the ResourceManager that was used to load the resource.

Returns

Returns a pointer to the ResourceManager.

IsCloneable()

virtual bool KatanaEngine::Resource::IsCloneable ( ) const

protectedpure virtual

Used to determine if the resource is cloneable.

Returns

Returns true if the resource is clonable, false otherwise.

Remarks

Resources that are stateless should not be cloneable; i.e. Fonts, Textures, etc. Resources that do contain state should be cloned to prevent state duplication. For example, an Animation that is shared (not cloned) would share the current frame. This would mean that they would always be playing in sync.

Implemented in KatanaEngine::Font, KatanaEngine::Texture, and KatanaEngine::Animation.

Load()

virtual bool KatanaEngine::Resource::Load ( const std::string &  path, ResourceManager *  pManager  )

pure virtual

Load the desired resource into memory.

Parameters

path	The path to the desired resource.
pManager	A pointer to the ResourceManager that will manage the resource.

Returns

Returns true if the resource was loaded, false otherwise.

Implemented in KatanaEngine::Font, KatanaEngine::RenderTarget, KatanaEngine::Animation, and KatanaEngine::Texture.

ParseComments()

void KatanaEngine::Resource::ParseComments ( std::string &  line )

protected

Removes c-style, single-line comments from a line of text.

Parameters

line	The line to remove the comments from.

Split()

void KatanaEngine::Resource::Split ( const std::string &  line, const char  delimeter, std::vector< std::string > &  elements  )

protected

Splits a string into a vector of strings.

Parameters

line	The string that will be split.
delimeter	The character that will determine the split locations.
elements	The vector where the split string elements will be stored.

TrimLine()

void KatanaEngine::Resource::TrimLine ( std::string &  line )

protected

Removes white-space at the front and end of a line of text.

Parameters

line	The line to remove the white-space from.
