Cache Class

Summary: Contains cache settings.

Module: aspose.imaging

Full Name: aspose.imaging.Cache

Properties

Name	Type	Access	Description
allocated_disk_bytes_count [static]	long	r	Gets the allocated disk bytes count.
allocated_memory_bytes_count [static]	long	r	Gets the allocated in-memory bytes count.
cache_folder [static]	string	r/w	Gets or sets the cache folder.
cache_type [static]	CacheType	r/w	Gets or sets the cache scheme used.
exact_reallocate_only [static]	bool	r/w	Gets or sets a value indicating whether reallocation should be exact or not. If reallocation is non exact the performance should be higher.
max_disk_space_for_cache [static]	int	r/w	Gets or sets the maximum available disk space for cache. The value specified is megabytes count.
max_memory_for_cache [static]	int	r/w	Gets or sets the maximum available memory for cache in memory. The value specified is megabytes count.
