Method Summary

Modifier and Type	Method and Description
long	getMaxBlobsBytesInMemory() Defines the maximum total size (in bytes) that all BLOBs may occupy in memory.
int	getPresentationLockingBehavior() This property defines if an instance of the Presentation class can be an owner of the source - file or stream during the instance lifetime.
java.lang.String	getTempFilesRootPath() The root path where temporary files will be created.
boolean	isTemporaryFilesAllowed() This property defines if temporary files can be created while working with BLOBs, what greatly decreases the memory consumption but requires permissions to create files.
void	setMaxBlobsBytesInMemory(long value) Defines the maximum total size (in bytes) that all BLOBs may occupy in memory.
void	setPresentationLockingBehavior(int value) This property defines if an instance of the Presentation class can be an owner of the source - file or stream during the instance lifetime.
void	setTempFilesRootPath(java.lang.String value) The root path where temporary files will be created.

Method Detail

getPresentationLockingBehavior

public final int getPresentationLockingBehavior()

This property defines if an instance of the Presentation class can be an owner of the source - file or stream during the instance lifetime. If the instance is an owner, it locks the source. This helps to improve memory consumption and performance while working with BLOBs, but the source (stream or file) can't be changed during Presentation's instance lifetime.

Specified by:

getPresentationLockingBehavior in interface IBlobManagementOptions

setPresentationLockingBehavior

public final void setPresentationLockingBehavior(int value)

This property defines if an instance of the Presentation class can be an owner of the source - file or stream during the instance lifetime. If the instance is an owner, it locks the source. This helps to improve memory consumption and performance while working with BLOBs, but the source (stream or file) can't be changed during Presentation's instance lifetime.

Specified by:

setPresentationLockingBehavior in interface IBlobManagementOptions

isTemporaryFilesAllowed

public final boolean isTemporaryFilesAllowed()

This property defines if temporary files can be created while working with BLOBs, what greatly decreases the memory consumption but requires permissions to create files.

All files will be deleted after work with the presentation will be finished.

Specified by:

isTemporaryFilesAllowed in interface IBlobManagementOptions

setTemporaryFilesAllowed

public final void setTemporaryFilesAllowed(boolean value)

This property defines if temporary files can be created while working with BLOBs, what greatly decreases the memory consumption but requires permissions to create files.

All files will be deleted after work with the presentation will be finished.

Specified by:

setTemporaryFilesAllowed in interface IBlobManagementOptions

getTempFilesRootPath

public final java.lang.String getTempFilesRootPath()

The root path where temporary files will be created. System temorary directory will be used by default. Hosting process should have permissions to create files and folders there.

Specified by:

getTempFilesRootPath in interface IBlobManagementOptions

setTempFilesRootPath

public final void setTempFilesRootPath(java.lang.String value)

The root path where temporary files will be created. System temorary directory will be used by default. Hosting process should have permissions to create files and folders there.

Specified by:

setTempFilesRootPath in interface IBlobManagementOptions

getMaxBlobsBytesInMemory

public final long getMaxBlobsBytesInMemory()

Defines the maximum total size (in bytes) that all BLOBs may occupy in memory. By default, all BLOBs are loaded into memory; only once this limit is reached are alternative mechanisms (such as temporary files) employed. Keeping BLOBs in memory maximizes performance but can lead to high memory usage. Use this property to tailor behavior to your environment or requirements.

This property is ignored if isTemporaryFilesAllowed()/setTemporaryFilesAllowed(boolean) is set to false, since memory is then the only storage location available and limiting in-memory BLOB usage has no effect.

The default value is 629,145,600 bytes (600 MB).

You may set this property to zero, but a small minimum amount of memory will still be reserved.

setMaxBlobsBytesInMemory

public final void setMaxBlobsBytesInMemory(long value)

Defines the maximum total size (in bytes) that all BLOBs may occupy in memory.
